Arbitrum On-Chain API
Live Arbitrum One on-chain data as an API, built on the open Blockscout explorer. Arbitrum is the largest Ethereum Layer-2 by total value locked (chain id 42161); gas and balances are denominated in ETH and fees are a fraction of mainnet. Pull network stats (total blocks and transactions, ETH price, live gas), a gas oracle with slow, average and fast prices in gwei, the most recent blocks and full block detail by height or hash. Look up any address for its ETH balance and contract status, any transaction by hash for its value, fee, status, sender and receiver, and any ERC-20 token by contract for its name, symbol, decimals, holders and USD rate. A universal search resolves addresses, tokens, blocks and transactions in one call. Real on-chain data, no key needed upstream. Ideal for Arbitrum wallets, block explorers, gas trackers, DeFi dashboards and on-chain analytics.

Ethereum L2 Transaktionskosten-API
Was es einen Benutzer tatsächlich kostet, auf jedem Ethereum Layer-2 Rollup zu transagieren, live und schlüssellos, unterstützt durch den öffentlichen growthepie-Datensatz. Die Basisschicht von Ethereum ist teuer, daher hat sich die meiste Aktivität auf Rollups verlagert – Arbitrum, Base, OP Mainnet, zkSync Era, Linea, Scroll, Starknet, Mantle, Mode, Metis, Celo, Taiko, Unichain – aber die Kosten einer Transaktion variieren stark zwischen ihnen, und das ist die Zahl, die ein Benutzer, der eine Chain auswählt, oder ein Entwickler, der entscheidet, wo er bereitstellt, tatsächlich wissen möchte. Dies beantwortet „Welches L2 ist gerade am günstigsten zu nutzen“, in einfachen Dollar. Der chains-Endpunkt ist die Rangliste: jeder verfolgte Rollup vom günstigsten an geordnet, jeweils mit seinen medianen Transaktionskosten (USD und ETH), Kosten für einen nativen Transfer, Kosten für einen Token-Swap, durchschnittlichen Kosten und Durchsatz (Transaktionen pro Sekunde und Mgas/s); Ethereum L1 ist als Basislinie enthalten, sodass Sie die L2-Ersparnis sehen können. Der chain-Endpunkt gibt die vollständigen aktuellen Kosten- und Leistungsdetails eines Rollups sowie eine kurze aktuelle Historie seiner medianen Kosten zurück. Der cheapest-Endpunkt kommt zur Sache – der günstigste Rollup gerade jetzt für einen einfachen Transfer und für einen Token-Swap, und wie viel günstiger das im Vergleich zu Ethereum L1 ist. Da die vorgelagerte Stelle USD auf vier Dezimalstellen rundet (so dass extrem günstige Rollups $0,00 anzeigen würden), werden die Dollarbeträge präzise aus den genauen ETH-Kosten jeder Chain und dem ETH-Preis, der aus derselben Nutzlast abgeleitet wird, zurückgewonnen – keine zweite Datenquelle. Dies ist der L2-Benutzertransaktionskosten-Schnitt – unterschieden vom L2-Wirtschaftsaktivitäts-Feed (aktive Adressen, Transaktionsanzahl, Rollup-Umsatz und -Gewinn: was die Chains verdienen, nicht was sie Sie kosten), vom Multi-Chain-Gas-Orakel (Gas-Stufen in gwei) und vom Blob-Datenverfügbarkeits-Gebührenmarkt (die L1-Kosten, die Rollups zahlen, um Daten zu posten). Kosten in USD und ETH, Durchsatz in TPS und Mgas/s, kein Key, nichts gespeichert.

GMX API
Live oracle prices from GMX, the leading decentralised perpetual-swap exchange on Arbitrum and Avalanche. Unlike order-book DEXs, GMX executes trades against its GLP/GM liquidity pools at prices set by a keeper-signed oracle that quotes a MIN and a MAX price per token — the execution band traders open and close positions against. The prices endpoint returns every supported token's min/max/mid oracle price and the execution spread; the price endpoint returns a single token by symbol; the tokens endpoint returns the supported-token registry (contract address, decimals, synthetic flag); the spread endpoint ranks tokens by their oracle execution spread (the on-chain cost band of trading that token on GMX). Every endpoint accepts a chain parameter (arbitrum default, or avalanche). Read live from GMX's public oracle, nothing stored. This is GMX's own pool-DEX oracle min/max-price and execution-spread layer — distinct from centralised-exchange tickers, aggregate price feeds and order-book DEX feeds such as dYdX and Hyperliquid.

Mantle Network API
Live on-chain data for Mantle (chain-id 5000), a modular EVM Layer 2 with the MNT native 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 MNT balance (in wei and whole MNT) 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, Layer-2 and Cosmos-chain APIs on the marketplace: this surfaces the Mantle network specifically.

Fraxtal Network API
Live on-chain data for Fraxtal (chain-id 252), an Optimistic-rollup EVM Layer 2 from Frax Finance that uses frxETH (Frax Ether) as its 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 frxETH balance (in wei and whole frxETH) 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 the Frax Finance protocol pools/yields feed and from other Layer-1, Layer-2 and Cosmos-chain APIs on the marketplace: this surfaces the Fraxtal chain itself.
