Sonic Network API

Live on-chain data for Sonic (chain-id 146), a high-performance EVM-compatible Layer 1 (the network formerly known as Fantom) with the S gas token. Read the chain status — chain id, latest block number, current gas price, node client version and sync state — fetch any block by number (or the latest) with its hash, parent hash, timestamp, transaction count, gas used and limit, base fee and proposer, read the current gas price and max priority fee in both wei and gwei, and look up any account address for its S balance (in wei and whole S) and transaction nonce. Addresses use the standard 0x EVM hex form. A short protective cache keeps responses fast while staying within a few seconds of the chain. Distinct from other Layer-1, Cosmos and Move-chain APIs on the marketplace: this surfaces the Sonic EVM network specifically.

Blockchair Multi-Chain Stats API

Live on-chain network statistics, mempool conditions and market data across the major UTXO blockchains and Ethereum, sourced from Blockchair. For any supported chain read the full network state — best block height, total and 24-hour block and transaction counts, mining difficulty, hashrate, coin circulation, on-chain transfer volume and chain size — or zoom into the mempool to see pending transactions, mempool size, transactions-per-second, the suggested fee per byte (or median gas price on Ethereum) and average and median transaction fees in native units and USD, or pull market data with the coin price in USD and BTC, 24-hour change, market capitalisation and dominance. Ten chains are covered: Bitcoin, Bitcoin Cash, Litecoin, Dogecoin, Dash, Zcash, Bitcoin SV, eCash, Groestlcoin and Ethereum. Distinct from single-chain mempool and gas feeds: this is one consistent multi-chain stats surface.

DIA Decentralized Price Oracle API

Live decentralized price-oracle data from DIA, with no key. DIA aggregates trade data across many CEXes and DEXes into transparent on-chain price feeds. Get a symbol quotation (current price, yesterday's price, 24h change and volume); an asset quotation by blockchain and contract address — the same multi-chain oracle feed smart contracts consume; the catalogue of quoted assets with their chain, address and volume; and the list of supported symbols. Distinct from CEX tickers and CoinGecko-style aggregators: these are oracle reference prices across 949 symbols and 5,500+ assets.

DexPaprika On-Chain DEX API

Live on-chain decentralized-exchange market data across 35+ blockchains, with no key. List every supported network with its 24h DEX volume, transaction count and pool count; read the DEXes active on any chain; pull the top liquidity pools ranked by volume; get full token detail with multi-window price stats; search across every chain for tokens, pools and DEXes; and read global coverage totals. The on-chain / DEX / liquidity-pool layer for DeFi dashboards, token analytics, trading and research — distinct from centralized-exchange ticker readers. Live from DexPaprika (by the CoinPaprika team); short cache only.

Tezos Bigmaps API

Lesen Sie Tezos' On-Chain-Key-Value-Speicher (Bigmaps) live vom öffentlichen TzKT-Indexer — kein API-Key erforderlich. Eine Bigmap ist Tezos' lazy-deserialisierte On-Chain-Map: die Datenstruktur, die Smart Contracts für die großen Dinge verwenden — Token-Ledger (wer besitzt was), NFT-Besitz, Berechtigungen und Metadaten. Der Tezos-Contract-Explorer listet Contracts und deren Schnittstelle auf, kann aber nicht die Bigmaps selbst durchsuchen, das typisierte Key/Value-Schema einer Bigmap lesen oder durch ihre Live-Key-Value-Einträge blättern. Dies öffnet das. Durchsuchen und bewerten Sie die Bigmaps nach Größe mit ihrem Pointer, besitzendem Contract, Pfad (z.B. "ledger"), Tags und Gesamt-/aktiven Key-Anzahlen; lesen Sie die Details einer Bigmap und ihr typisiertes Key/Value-Schema (welche Form die Key- und Value-Zeilen haben, z.B. ein Address-to-Nat-Token-Ledger); und blättern Sie durch die Live-Key-Value-Einträge einer Bigmap — die tatsächlichen On-Chain-Daten, wie die Address-to-Balance-Zeilen eines Token-Ledgers oder die Besitzer-Zeilen einer NFT-Sammlung. Die Speicher-/Datenebene für Tezos-Explorer, Indexer, Token-Dashboards und Analysen. Unterscheidet sich vom Tezos-On-Chain-Reader (Account-Status), dem Smart-Contract-Explorer, dem FA-Token-Register und dem .tez-Namensleser. Live vom Indexer; nur kurzer Cache.

Tezos Governance API

Tezos' berühmte selbständernde On-Chain-Governance, live vom öffentlichen TzKT-Indexer – kein API-Key, nichts gecached. Tezos aktualisiert sich selbst durch eine On-Chain-Abstimmung: Bakers schlagen Protokolländerungen vor und durchlaufen dann einen Fünf-Perioden-Zyklus – Vorschlag, Erkundung, Abkühlung, Förderung und Annahme – jede mit eigenem Quorum und Supermajoritätsschwellen. Während der On-Chain-Reader Konten abdeckt und der Bakers-Reader Staking abdeckt, zeigt dieser die Governance-Ebene, die sie übersehen. Lesen Sie die aktuelle Abstimmungsperiode vollständig: ihre Art, Status, Perioden- und Epochenindex, die Ja/Nein/Enthaltung-Stimmauszählung mit jeder Seite Stimmkraft und Anteil, die Quorum- und Supermajoritätsschwellen der Stimmzettel und die Anzahl der teilnehmenden Bakers. Listen Sie jeden jemals on-chain gemachten Protokolländerungsvorschlag mit seinem Initiator, Upvotes, Stimmkraft, Status und Tezos Agora-Diskussionslink (die menschlichen Aliase wie "Athens A" inbegriffen). Und durchsuchen Sie die Historie der Abstimmungsperioden, neueste zuerst. Die Protokoll-Governance-Ebene für Tezos-Wallets, Governance-Dashboards, Bakers und Analysen. Live von api.tzkt.io.

Chainlink Price Feeds API

Die On-Chain-Preise, auf denen DeFi tatsächlich läuft, live und ohne API-Key direkt aus Chainlinks Price-Feed-Verträgen auf Ethereum ausgelesen. Chainlink ist das dominierende Oracle: Ein dezentrales Netzwerk schreibt jeden Preis on-chain und aktualisiert ihn bei einem Heartbeat oder wenn er einen Abweichungsschwellenwert überschreitet. Tausende von Lending-, Perpetual- und Stablecoin-Protokollen lesen genau diese Zahl, um Sicherheiten zu bewerten und Liquidationen auszulösen. Wichtig ist nicht nur der Preis, sondern ob der Feed aktuell ist – ein veralteter Chainlink-Feed ist der Grund, warum DeFi-Protokolle brechen – und genau diese On-Chain-Aktualität wird hier offengelegt. Der Feeds-Endpunkt listet jeden verfolgten Chainlink-Feed (Krypto, Stablecoins und FX) mit seiner aktuellen On-Chain-Antwort, wie viele Sekunden seit der letzten Aktualisierung vergangen sind und ob er aktuell ist. Der Feed-Endpunkt gibt die vollständigen Details eines Paares nach Namen zurück, einschließlich der Runden-ID, des Aktualisierungszeitstempels und der Feed-Vertragsadresse. Der Health-Endpunkt ist die Oracle-Überwachungsansicht: Wie viele Feeds sind aktuell versus veraltet, der älteste Feed und das durchschnittliche Aktualisierungsalter – das On-Chain-Zuverlässigkeitsbild, das eine einfache Preis-API nicht liefern kann. Jeder Preis wird aus dem latestRoundData des Feeds gelesen und mit den eigenen On-Chain-Dezimalstellen des Feeds skaliert (USD-Feeds verwenden 8); die Aktualisierungszeit ist das updatedAt des Vertrags. Dies ist der Chainlink-On-Chain-Oracle-Schnitt – unterschieden von den Off-Chain-Oracle-Preis-APIs (die einen Preis, aber nicht die Runde und Aktualität des On-Chain-Feeds liefern) und den Börsenpreis-Feeds. Preise sind in der Quote-Einheit des Feeds (hier USD); Zeiten sind UTC. Kein API-Key, nichts wird über einen kurzen Cache hinaus gespeichert.

Stablecoin Chain Distribution API

Where dollar stablecoin liquidity actually lives, read live and keyless from each blockchain. USDC and USDT are issued natively on many chains, and the split between them is one of the most-watched signals in the layer-2 wars: Ethereum mainnet still holds the bulk, but Base, Arbitrum and the other rollups have been pulling stablecoin supply across as activity migrates. This API reads the native USDC and USDT supply directly from the token contract on each chain — Ethereum, Base, Arbitrum, Optimism, Polygon and Avalanche — not a single chain and not an aggregator, so you see the real on-chain distribution. The stablecoin endpoint takes a symbol (USDC or USDT) and returns its supply on every tracked chain, ranked, each with its share of that stablecoin and the Ethereum-versus-rollup split. The chains endpoint ranks the chains by their total native stablecoin liquidity (USDC and USDT together) — which chain hosts the most dollars. The summary endpoint is the top-down view: total USDC, total USDT, the combined total, the USDT-to-USDC ratio, and Ethereum's dominance versus the share that has moved to the rollups. Because USDC and USDT are dollar-pegged and read at the token's own on-chain decimals (read live from each contract, never assumed), the supply equals the dollars of stablecoin on that chain; only natively-issued supply is counted (bridged and peg tokens are excluded). This is the stablecoin chain-distribution cut — distinct from the single-chain token feeds, the generic stablecoin-supply aggregators and the price feeds: it is specifically the cross-chain liquidity map. Amounts are in US dollars. No key, nothing stored beyond a short cache.

Bitcoin Valuation Models API

Die Bitcoin-Zyklus-Timing-Bewertungsmodelle, die Ihnen sagen, ob BTC historisch günstig oder teuer ist, live und schlüssellos aus Preis (Yahoo Finance Tageschlusskurse) und On-Chain-Daten (dem öffentlichen blockchain.com Charts-Feed) berechnet. Dies sind keine rohen Zeitreihen und kein Preisfeed – es sind die abgeleiteten Indikatoren, die On-Chain-Analysten und Zyklushändler beobachten, um zu beurteilen, wo Bitcoin zwischen tiefem Wert und Euphorie steht. Der mayer-Endpunkt gibt das Mayer Multiple zurück – Preis geteilt durch seinen 200-Tage-Durchschnitt – der einfachste und beständigste Über-/Unterbewertungsindikator (Käufe unter ~1 und Verkäufe über ~2,4 haben historisch gesehen Zyklen gut getimt). Der puell-Endpunkt gibt das Puell Multiple zurück – tägliche Miner-Einnahmen geteilt durch ihren 365-Tage-Durchschnitt – ein Miner-seitiger Indikator, der Kapitulationsböden (unter ~0,5) und Spitzen (über ~4) markiert. Der nvt-Endpunkt gibt das NVT-Verhältnis zurück – Marktkapitalisierung geteilt durch den 90-Tage-Durchschnitt des On-Chain-Transaktionswerts – Bitcoins Antwort auf ein Kurs-Gewinn-Verhältnis, wobei ein hoher Wert bedeutet, dass der Preis im Verhältnis zum tatsächlich on-chain abgewickelten Wert hoch ist. Der s2f-Endpunkt gibt das Stock-to-Flow-Knappheitsverhältnis zurück – zirkulierendes Angebot geteilt durch die realisierte jährliche Emission (der Fluss, gemessen empirisch aus dem tatsächlich in den letzten 365 Tagen geminten Angebot); das daraus abgeleitete S2F-Preismodell ist enthalten, aber klar als umstritten und historisch überoptimistisch gekennzeichnet (die Antwort berichtet auch, wie weit das Modell über dem tatsächlichen Preis liegt). Der summary-Endpunkt stellt alle vier nebeneinander mit einer aggregierten Zyklusbewertung dar. Dies ist der Bewertungsmodell-/Zyklusindikator-Schnitt – unterschieden von den rohen Bitcoin-On-Chain-Zeitreihen-Feeds (die Hashrate, Miner-Einnahmen und Transaktionszahlen melden, aber nicht die abgeleiteten Verhältnisse), dem Netzwerksicherheits-Feed (Schwierigkeit, Hashrate, Halving), dem Block-Explorer-Feed und dem Krypto-Makro-Korrelations-Feed. Verhältnisse sind einheitenlos; Modell- und tatsächliche Preise sind in USD. Kein Key, nichts wird über einen kurzen Cache hinaus gespeichert.

Bitcoin Hashrate & Difficulty API

Bitcoins Netzwerk-Sicherheits- und Mining-Ökonomie-Schicht, live und schlüssellos, betrieben von mempool.space — Hashrate, Mining-Schwierigkeit, der Countdown zur Schwierigkeitsanpassung, der Halving-Countdown und die Block-Belohnungs-Ökonomie pro Fenster. Dies sind die Zahlen, die beschreiben, wie schwer Bitcoin zu minen ist und wie sicher die Chain ist, kein Preis und kein Block-Explorer. Der Difficulty-Endpunkt ist das Flaggschiff: die aktuelle Mining-Schwierigkeit plus der Live-Countdown zur Anpassung — wie weit wir im aktuellen 2016-Block-Epoche sind, die prognostizierte Größe der nächsten Anpassung (Bitcoin passt sich alle zwei Wochen an, damit Blöcke ~10 Minuten auseinander bleiben), die verbleibenden Blöcke bis zur Anpassung, das geschätzte Anpassungsdatum und die realisierte durchschnittliche Blockzeit. Der Hashrate-Endpunkt gibt die aktuelle Netzwerk-Hashrate in EH/s sowie eine historische Hashrate- und Difficulty-Zeitreihe über ein ausgewähltes Fenster (1m bis alle) zurück. Der Halving-Endpunkt ist der Countdown bis zur nächsten Block-Subventions-Halbierung — die aktuelle Blockhöhe, die aktuelle Subvention in BTC, der nächste Halving-Block und wie viele Blöcke und Tage verbleiben. Der Rewards-Endpunkt gibt die Block-Belohnungs-Ökonomie über ein aktuelles Fenster zurück: die gesamte Miner-Belohnung, den Gebührenanteil und die Durchschnittswerte pro Block, alle in BTC. Dies ist der Bitcoin Difficulty / Hashrate / Halving Cut — unterschieden vom Bitcoin Block-Explorer-Feed (Mempool, Gebühren, Blöcke, Adressen, Transaktionen), dem Mining-Pool-Verteilungs-Feed (wer findet die Blöcke und wie zentralisiert) und dem Multi-Coin-Mining-Profitability-Feed. Hashrate in EH/s, Difficulty roh und in Billionen, Belohnungen in BTC, Zeiten in UTC. Kein Key, nichts gespeichert.

Solana Validators & Staking API

Wer sichert Solana und wie dezentral ist es, direkt von einem öffentlichen Solana RPC-Knoten gelesen. Solana ist Proof-of-Stake: Validatoren stimmen mit dem ihnen delegierten SOL ab, und die Verteilung dieses Einsatzes bestimmt sowohl Belohnungen als auch Sicherheit. Der Validatoren-Endpunkt listet Validatoren nach aktiviertem Einsatz auf, mit deren Einsatz in SOL, ihrem Anteil am Gesamteinsatz, ihrer Provision und ob sie säumig sind (aktuell nicht abstimmend). Der Staking-Endpunkt gibt die Staking-Ökonomie zurück – den gesamten aktiven Einsatz, das zirkulierende und gesamte SOL-Angebot, den Prozentsatz des Angebots, der eingesetzt ist, die aktuelle Inflationsrate aufgeschlüsselt in ihre Gesamt-, Validatoren- und Foundation-Komponenten sowie die aktuelle Epoche mit ihrem Fortschritt. Der Zentralisierungs-Endpunkt berechnet die Einsatz-Zentralisierungsmetriken – den Nakamoto-Koeffizienten (die wenigsten Validatoren, die zusammen mehr als ein Drittel des Einsatzes kontrollieren, die Menge, die die Chain unter byzantinisch-fehlertoleranten Konsens stoppen könnte), den Anteil der Top-10 und Top-20 am Einsatz und den Herfindahl-Konzentrationsindex. Dies ist der Solana-Validator-, Staking- und Dezentralisierungs-Datenschnitt, unterschieden von der Solana-On-Chain-Account/Transaction-API und den anderen Staking- und Exchange-APIs im Katalog. Live von einem öffentlichen RPC, kein Key auf der Upstream-Seite, nichts gespeichert.

Bitcoin Mining Pool Distribution API

Who actually mines Bitcoin's blocks, served from the public blockchain.com pools feed. The distribution endpoint ranks the mining pools by the blocks they found over a window (24 hours to 10 days), with each pool's share of blocks and its estimated share of the network hash rate (in EH/s). The centralization endpoint turns that into mining-decentralisation metrics — the top pool's share, the top-3 and top-5 share, the Nakamoto coefficient (the fewest pools that together control more than half of the attributed blocks, a headline measure of how centralised mining is), the Herfindahl concentration index, and the share of blocks not attributed to a known pool. The pool endpoint looks up a single pool's blocks, share, rank and estimated hash rate. This is the mining-pool and hash-rate-distribution / centralisation data-cut — distinct from the mempool-snapshot, the aggregate on-chain-metrics and the price-feed APIs in the catalogue. Estimated per-pool hash rate = block share times network hash rate. Live, no key on the upstream, nothing stored.

Bitcoin Historical Metrics API

Die langfristige On-Chain-Ökonomie von Bitcoin als Zeitreihe, bereitgestellt aus dem öffentlichen blockchain.com-Charts-Feed. Während Snapshot-APIs den aktuellen Kettenzustand melden, liefert diese API die Historie: wie sich Hashrate, Mining-Schwierigkeit, Miner-Einnahmen, tägliche Transaktionsanzahl, Transaktionsgebühren, Marktpreis, Marktkapitalisierung, zirkulierendes Angebot, Mempool-Größe, durchschnittliche Blockgröße, geschätztes On-Chain-Transaktionsvolumen, tägliche eindeutige Adressen, UTXO-Anzahl und mediane Bestätigungszeit über Monate und Jahre entwickelt haben. Der Metrik-Endpunkt gibt die vollständige tägliche Zeitreihe einer Metrik über ein ausgewähltes Fenster (30 Tage bis alle Zeiten) mit zusammenfassenden Statistiken zurück – erster, letzter, Änderung, prozentuale Änderung, Minimum, Maximum und Durchschnitt. Der neueste-Endpunkt gibt den aktuellen Wert einer Metrik mit ihrer Änderung gegenüber dem vorherigen Wert und gegenüber 30 Tagen zurück. Der Metriken-Endpunkt listet jede verfügbare Metrik mit ihrer Einheit und Kategorie auf. Dies ist die historische und Chart-Ansicht der Bitcoin-Netzwerkökonomie – abweichend von den Live-Mempool-Snapshot-, Multi-Chain-Netzwerkstatistik- und Preis-Feed-APIs im Katalog. Live, kein API-Key auf der Upstream-Seite, nichts gespeichert.

growthepie L2 Economics API

Live economic-activity metrics for Ethereum Layer-2 rollups — Arbitrum, Base, Optimism, zkSync, Linea, Scroll, Polygon and more — powered by the public growthepie.xyz feed, no key, nothing stored. This is the L2 fundamentals cut: not a single chain's block or gas data, but how much each rollup is actually used and what it earns. The chains endpoint lists the tracked rollups. The chain endpoint returns one rollup's latest metrics: daily active addresses, transaction count, fees paid, on-chain profit (the fees it keeps after paying Ethereum to post its data), median transaction cost, stablecoin supply, total value locked, market cap and fully-diluted valuation. The metric endpoint ranks every rollup by a single metric, so you can see at a glance which L2 leads on users, fees or profit and how the scaling race is shifting. Track the real adoption and economics of the rollup ecosystem as live JSON. This is the L2 activity / economics cut — distinct from the per-chain on-chain (block and gas) APIs and the TVL-only APIs in the catalogue.

Options DEX API

Live on-chain crypto options trading volume — the decentralized options market where protocols like Derive, Aevo, Premia, Ithaca and Rysk let users trade calls and puts on-chain, powered by the public DeFiLlama options feed, no key, nothing stored. This is distinct from a centralized options exchange order book: it measures the volume actually flowing through on-chain options venues. The overview endpoint returns the whole on-chain options market's volume over the last 24 hours, 7 days and 30 days plus every protocol ranked by what it trades, measured as notional (contract face value, the default) or premium (what option buyers actually paid). The protocol endpoint returns a single protocol's notional and premium volume side by side across 24h / 7d / 30d / all-time. The chain endpoint returns the options volume and top venues for one blockchain. See which on-chain options venue leads and how DeFi options flow shifts. This is the on-chain options-volume cut of DeFi — distinct from the centralized options-chain, spot-DEX, swap-aggregator, fees and perpetual APIs in the catalogue.

Ethereum Supply & Burn API

Live Ethereum monetary-policy data — the total ETH supply, how much of it is being created versus destroyed, and the EIP-1559 fee burn that can make ether deflationary (the "ultrasound money" thesis), powered by the public ultrasound.money feed, no key, nothing stored. The supply endpoint returns the current circulating ETH supply and its net change over the last 5 minutes, hour, day, week and month — a negative change means more ETH was burned than issued, i.e. net deflation. The burn endpoint returns the ETH destroyed by the base-fee burn over each window in both ETH and USD, the live burn rate in ETH per minute and the current deflationary streak. The basefee endpoint returns the current base fee per gas, the blob base fee and the ETH price. The leaderboard endpoint ranks the apps and contracts burning the most ETH right now. Track ETH issuance, the burn and whether ether is deflating as live JSON. This is the ETH supply / issuance / burn cut — distinct from the gas-fee, on-chain and price APIs in the catalogue.

DEX Aggregators API

Live trading volume routed through DeFi DEX aggregators — Jupiter, 1inch, CowSwap, Paraswap, OKX Swap, KyberSwap and more — powered by the public DeFiLlama aggregators feed, no key, nothing stored. Aggregators don't hold liquidity themselves: they split each trade across many underlying decentralized exchanges to get the best price, so their volume is the single best measure of where real swap flow actually routes. The overview endpoint returns total aggregator volume over the last 24 hours, 7 days and 30 days plus every aggregator ranked by what it routes, with its category and the chains it covers. The aggregator endpoint returns a single aggregator's volume across 24h / 7d / 30d / all-time. The chain endpoint returns aggregator volume and the top routers for one blockchain (Solana, Ethereum, Base). See which router dominates each chain and how swap flow shifts. This is the swap-routing / aggregator-volume cut of DeFi — distinct from the spot-DEX-volume, fees-and-revenue, TVL and exchange-ticker APIs in the catalogue.

Crypto Hacks API

Eine Live-Datenbank von Kryptowährungs- und DeFi-Hacks, Exploits und Diebstählen – jeder größere On-Chain-Diebstahl, der aufgezeichnet wurde, betrieben durch den öffentlichen DeFiLlama-Hacks-Datensatz, kein API-Key, nichts gespeichert. Jeder Vorfall enthält das Opfer, den gestohlenen Betrag in US-Dollar, das Datum, die Angriffstechnik (Flash-Loan-Oracle-Manipulation, Reentrancy, Kompromittierung privater Schlüssel, Access-Control-Exploit und mehr), eine übergeordnete Klassifizierung, die beteiligte(n) Chain(s), den Zieltyp (DeFi-Protokoll, zentralisierte Börse, Bridge, Wallet, Token) und wie viel, falls vorhanden, später zurückgegeben wurde. Der Hacks-Endpunkt gibt die Vorfallsliste neueste zuerst zurück, filterbar nach Chain, Technik, Zieltyp, Klassifizierung, Jahr und Mindestverlust. Der Biggest-Endpunkt ordnet die größten Exploits aller Zeiten nach gestohlenen Dollar – von den milliardenschweren Bridge- und Börsenverstößen abwärts. Der Stats-Endpunkt aggregiert den gesamten Datensatz: insgesamt gestohlen, Anzahl der Vorfälle, zurückgegebene Gelder und Aufschlüsselungen nach Angriffstechnik, Chain, Zieltyp und Jahr. Dies ist der Krypto-Sicherheits- und Exploit-Verlaufsschnitt – Risiko- und Post-Mortem-Daten, die sich von den Preis-, Markt-, TVL-, Gebühren- und On-Chain-APIs im Katalog unterscheiden.

DeFi Fees & Revenue API

Live-Daten zu den Gebühren, die Nutzer an DeFi-Protokolle zahlen, und den Einnahmen, die diese Protokolle tatsächlich behalten – die Ansicht „Welche Protokolle verdienen Geld“, eine andere Ebene als der Total Value Locked. TVL ist das, was eingezahlt wird; Gebühren sind das, was Nutzer für die Nutzung eines Protokolls zahlen; Einnahmen sind der Anteil, den das Protokoll oder seine Token-Inhaber behalten. Angetrieben durch den öffentlichen DeFiLlama-Gebühren-Feed, kein Key, nichts wird gespeichert. Der Übersichts-Endpunkt gibt die gesamten DeFi-Gebühren (oder -Einnahmen) der letzten 24 Stunden, 7 Tage und 30 Tage zurück, sowie jedes Protokoll, sortiert nach seinen Einnahmen, mit seiner Kategorie und Chains. Der Protokoll-Endpunkt gibt die Gebühren- und Einnahmenzahlen eines einzelnen Protokolls nebeneinander für 24h / 7d / 30d / Gesamtzeitraum zurück (z. B. Aave, Uniswap, Lido). Der Chain-Endpunkt gibt die Gebühren- oder Einnahmensumme und die umsatzstärksten Protokolle für eine Blockchain zurück (Ethereum, Solana, Base). Wechseln Sie jede Liste zwischen Bruttogebühren und einbehaltenen Einnahmen mit einem einzigen Metrik-Parameter. Dies ist der Gebühren-und-Einnahmen-Bereich von DeFi – abgegrenzt von den TVL-, DEX-Volumen-, Exchange-Ticker- und Coin-Markets-APIs im Katalog.

Hive Engine API

Live-Daten von der Hive-Engine Smart-Contract Sidechain – einem Layer-2 Token-Register und dezentralen Exchange, der auf der Hive-Blockchain aufbaut. Rufen Sie den On-Chain-Registrierungseintrag eines beliebigen Hive-Engine-Tokens ab (Emittent, Genauigkeit, maximales / aktuelles / zirkulierendes Angebot, Staking-Status und gesamtes Staked), lesen Sie seine Live-DEX-Marktdaten (letzter Preis in HIVE, höchstes Gebot, niedrigstes Angebot, 24h-Volumen und die tägliche Preisänderung), ziehen Sie die Richlist seiner größten Halter mit ihrem Liquid-Balance, Staked-Betrag und Delegationen, und streamen Sie die aktuellsten Fills auf seinem HIVE-Markt (Käufer, Verkäufer, Menge, Preis und Zeit). Symbole sind Hive-Engine-Tokens wie LEO, BEE, SWAP.HIVE oder SPS; Preise und Marktvolumen werden in HIVE, der Basis-Chain-Münze, angegeben. Dies ist die Token-Sidechain / On-Chain-DEX-Ansicht – pro Token Angebot, Halter und ein interner Orderbuch-Markt – abweichend von den Single-Venue-Exchange-Tickern, den Cross-Exchange-Coin-Märkten und den Basis-Chain-On-Chain-APIs im Katalog. Live und direkt von einem öffentlichen Hive-Engine-RPC-Knoten gelesen – nichts wird gespeichert.

Monero Network API

Live network and blockchain data from Monero (XMR), the leading privacy cryptocurrency — no key, nothing stored. The network endpoint returns the live chain state: block height, difficulty, an estimated network hashrate, the mempool size, peer connections, hard-fork version and median block size. The block endpoint returns a block by height — its hash, size, timestamp and transaction count. The mempool endpoint returns the current unconfirmed-transaction pool with a sample of pending transactions and their fees. Data comes live from a public Monero blockchain-explorer node. Monero is privacy-preserving, so individual balances and amounts are unobservable — this is network/aggregate data, distinct from the exchange-ticker, market and transparent-chain APIs in the catalogue. Built for Monero dashboards, network monitors, mining tooling and explorers.

api.oanor.com/monero-api

TON Blockchain API

Live on-chain data from The Open Network (TON / Toncoin), the layer-1 blockchain integrated with Telegram — no key, nothing cached, nothing stored. The network endpoint returns the latest masterchain block (the chain tip). The account endpoint returns any TON address's balance (in TON and nanoTON), account state and last-transaction reference. The transactions endpoint returns an address's most recent transactions with counterparties, value, fee and time. Addresses accept raw (0:.. / -1:..) or user-friendly (EQ.. / UQ..) form. This is live blockchain and network data straight from the public TON node API — distinct from the exchange-ticker, price and market APIs in the catalogue. Built for TON wallets, explorers, dashboards and on-chain analytics.

Chain Stats API

Live blockchain network statistics across 18 chains, from the public Blockchair feed. Get one network's full stats — price, market cap and dominance, block height, 24h transactions, circulating supply, difficulty, hashrate, mempool size and average fee; compare the major chains side by side, ranked by market cap; and read a chain's mempool congestion (pending transactions, size and fees). A multi-chain network-stats layer — distinct from single-coin price feeds and Bitcoin-only on-chain APIs: it answers how each blockchain is performing right now and how they compare. Live, with a 10-minute upstream cache.

Ravencoin On-Chain API

Live on-chain data from the Ravencoin (RVN) blockchain — a UTXO chain purpose-built for issuing and transferring digital assets and tokens, secured by the ASIC-resistant KAW-POW proof-of-work — via the public Trezor Blockbook explorer, clean JSON and no cache. Read the chain state (best block height, difficulty, sync status and node version); fetch a block by height or hash; look up an address's RVN balance, total received and sent and transaction count; or resolve a transaction's block, value, fee and confirmations. Read live from Ravencoin, nothing stored. This is Ravencoin's own KAW-POW asset-chain UTXO ledger — distinct from the Bitcoin, Dash, Decred, Nervos and other on-chain APIs and from price feeds: the RVN network built for tokenisation.

api.oanor.com/ravencoin-api

Dash On-Chain API

Live-On-Chain-Daten aus der Dash (DASH)-Blockchain – einer auf Zahlungen ausgerichteten Kryptowährung – über den öffentlichen Dash Insight Explorer, sauberes JSON und ohne Cache. Dash verwendet X11 Proof-of-Work plus eine zweite Ebene von besicherten Masternodes, die InstantSend (nahezu sofortige gesperrte Zahlungen) und ChainLocks ermöglichen, sowie eine On-Chain-Treasury, die Vorschläge finanziert. Lesen Sie den Chain-Status (Blockhöhe, Schwierigkeit, Peer-Verbindungen, Protokollversion und Relay-Gebühr); rufen Sie einen Block nach Höhe oder Hash ab; suchen Sie den DASH-Saldo, den Gesamtbetrag der empfangenen und gesendeten Transaktionen sowie die Anzahl der Transaktionen einer Adresse; oder lösen Sie den Block, den Wert, die Gebühr, die Anzahl der Ein-/Ausgaben und den InstantSend-Sperrstatus einer Transaktion auf. Lesen Sie live von Dash, nichts wird gespeichert. Dies ist DASHs eigenes X11-, Masternode-Tier- und InstantSend-Ledger – unterschieden von den Bitcoin-, Decred-, Ergo-, Nervos- und anderen On-Chain-APIs sowie von Preis-Feeds.

Conflux On-Chain API

Live on-chain data from the Conflux (CFX) network — a high-throughput Layer-1 that orders blocks with the Tree-Graph DAG consensus (not a single chain) and runs two spaces: the native Core space (cfx: addresses) and an EVM-compatible eSpace. Served live from a public Conflux Core-space JSON-RPC node as clean JSON. Conflux is distinctive for its storage-collateral model and a built-in proof-of-stake interest rate. Read the chain state (chain id, current epoch, block number, latest-finalized epoch, pending-tx count and the PoS interest rate); the supply (circulating, issued, staked and storage-collateral CFX); a block (the pivot block of an epoch) by epoch number or hash; or a Core-space address's CFX balance and staked balance. Read live from Conflux, nothing cached. This is Conflux's own Tree-Graph, storage-collateral and PoS layer — distinct from the Bitcoin, Decred, Ergo, Nervos and other on-chain APIs and from price feeds.

api.oanor.com/conflux-api

Nervos CKB On-Chain API

Live on-chain data from the Nervos Common Knowledge Base (CKB) via the official Nervos explorer — clean JSON, no cache. Nervos CKB is a proof-of-work Layer-1 built on the Cell model — a generalised UTXO where every cell can hold state and code — secured by the Eaglesong hash and governed in epochs, with a native state-rent / deposit system (NervosDAO) that pays interest for locking CKB. Read the chain state (tip block, current epoch, block time, difficulty and hashrate); browse the most recent blocks with miner and reward; fetch a single block by number or hash; look up an address's CKB balance, its NervosDAO deposit and compensation, live-cell count and UDT token accounts; or resolve a transaction's block, fee and type. Read live from Nervos, nothing stored. This is Nervos CKB's own Cell-model, NervosDAO and PoW layer — distinct from the Bitcoin, Decred, Ergo and other on-chain APIs and from price feeds.

Ergo On-Chain & Native Token API

Live on-chain data from the Ergo (ERG) blockchain via the public Ergo Platform explorer — clean JSON, no cache. Ergo is a proof-of-work cryptocurrency built on the extended-UTXO (eUTXO) model with first-class native tokens, Sigma-protocol smart contracts and storage rent — a distinctly different design from account-based chains. Read the network head (best block height, mining difficulty, miner reward); browse the most recent blocks with their miner, size, difficulty and reward; fetch a single block by header id; look up any address's confirmed ERG balance and every native token it holds; or resolve a native token's id, name, decimals, emission amount and description. Read live from Ergo, nothing stored. This is Ergo's own extended-UTXO chain, native-token and Autolykos-PoW layer — distinct from the Bitcoin, Decred, EOS, Internet Computer and other on-chain APIs and from price feeds.

Decred On-Chain & Staking API

Live on-chain data from the Decred (DCR) blockchain via the public dcrdata explorer — clean JSON, no cache. Decred is a hybrid proof-of-work / proof-of-stake cryptocurrency with on-chain governance: blocks are mined by PoW but validated by PoS tickets bought from a ticket pool, so stakeholders directly control the chain. Read the network head (best block, PoW difficulty, stake difficulty, live ticket pool); the staking layer (ticket-pool size and value, the current and next ticket price and next-price estimates); the coin supply (mined vs the 21M ultimate cap and percent issued); any block by height or hash; and any address's received, sent and unspent DCR. Read live from Decred, nothing stored. This is Decred's own hybrid PoW/PoS, ticket-staking and on-chain-governance layer — distinct from the Bitcoin, EOS, Internet Computer and other on-chain APIs and from price feeds.

The token endpoint returns an ERC-20 token's metadata (name, symbol, decimals, total supply, holders) by contract address, and search runs a universal lookup across addresses, tokens, blocks and transactions. Gas, balances, values and fees are denominated in EWT, the native coin. Real on-chain data straight from the explorer, refreshed every call — no key. 9 endpoints. For multi-chain coverage combine with the other oanor chain APIs (Ethereum, Base, Arbitrum and more).

Syscoin Chain API

Live on-chain data for Syscoin NEVM — an EVM Layer 1 merge-mined with Bitcoin — via its public Blockscout explorer (no wallet, no key). The stats endpoint returns chain-wide totals (blocks, transactions, addresses, average block time, gas used); gas gives the current gas-price oracle (slow/average/fast). Blocks lists the latest blocks, and a single block resolves by height or by hash with its transaction count, gas, miner and timestamp. The address endpoint returns any account's SYS balance, nonce, contract flag and token holdings; transaction resolves a tx by hash with its from/to, value in SYS, fee, status and block. The token endpoint returns an ERC-20 token's metadata (name, symbol, decimals, total supply, holders) by contract address, and search runs a universal lookup across addresses, tokens, blocks and transactions. Gas, balances, values and fees are denominated in SYS, the native coin. Real on-chain data straight from the explorer, refreshed every call — no key. 9 endpoints.

Etherlink Chain API

Live on-chain data for Etherlink — a Tezos-secured EVM Layer 2 — via its public Blockscout explorer (no wallet, no key). The stats endpoint returns chain-wide totals (blocks, transactions, addresses, average block time, gas used); gas gives the current gas-price oracle (slow/average/fast). Blocks lists the latest blocks, and a single block resolves by height or by hash with its transaction count, gas, miner and timestamp. The address endpoint returns any account's XTZ balance, nonce, contract flag and token holdings; transaction resolves a tx by hash with its from/to, value in XTZ, fee, status and block. The token endpoint returns an ERC-20 token's metadata (name, symbol, decimals, total supply, holders) by contract address, and search runs a universal lookup across addresses, tokens, blocks and transactions. Gas, balances, values and fees are denominated in XTZ, the native coin. Real on-chain data straight from the explorer, refreshed every call — no key. 9 endpoints.
