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.

The Bitcoin hashprice — the single number every Bitcoin miner watches: how many US dollars a unit of hashing power earns in a day. It is the mining industry's revenue benchmark (the "Hashprice Index"), and it falls every time the difficulty rises, the block subsidy halves, fees dry up or the price drops. This computes it live and keyless from on-chain data and the BTC price: the daily Bitcoin the whole network mines (block subsidy plus transaction fees), the network hashrate, and the dollar price of Bitcoin. The hashprice endpoint returns the current hashprice in dollars per PH/s per day and per TH/s per day, with the inputs behind it — the network hashrate, the daily Bitcoin mined, the share of that which is fees, and the BTC price. The breakeven endpoint turns it into a profitability check: give it your electricity cost (USD per kWh) and your rig's efficiency (J/TH) and it returns the daily revenue, power cost and profit per TH/s, the margin, and the breakeven hashprice at which you would mine at a loss. The asic endpoint runs the same maths over today's popular ASIC miners (Antminer S21, S19 XP, Whatsminer M60 and more) at your electricity cost — daily revenue, power cost and profit for each machine, ranked. This is the hashprice / mining-profitability cut — distinct from the network-security feed (difficulty, hashrate, halving), the multi-coin mining-economics feed (which ranks coins by a relative profitability index, not the dollar hashprice) and the mining-pool-distribution feed. Hashprice is in USD per PH/s and per TH/s per day; costs in USD. No key, nothing stored beyond a short cache.

How much Bitcoin lives on Ethereum, and through whose vault, read live and keyless straight from the Ethereum blockchain. Bitcoin itself can't run in DeFi, so it gets "wrapped": a custodian (or a decentralised bridge) locks real BTC and mints a 1:1 ERC-20 that trades on Ethereum. WBTC (BitGo) was the original and long the only one that mattered, but after the 2024 custody controversy a competitive market opened up — Coinbase's cbBTC, the decentralised tBTC (Threshold), Lombard's LBTC, Kraken's kBTC and others now split the pie. The wrappers endpoint lists every tracked wrapped-Bitcoin token ranked by the BTC it holds, each with its issuer/custodian, the BTC backing it, its US-dollar value and its share of all wrapped BTC, plus the totals. The token endpoint returns one wrapper's detail by symbol. The dominance endpoint is the concentration view — WBTC's share, the split between custodial wrappers (a company holds the BTC) and the decentralised one, and how concentrated the market is — the counterparty-risk picture for Bitcoin in DeFi. Each token's BTC backing is read as its on-chain total supply divided by its own decimals (read live from the contract — they are not all 18: WBTC and cbBTC use 8, tBTC uses 18), which equals the BTC held because every wrapper is minted 1:1 against locked Bitcoin. This is the wrapped-BTC / BTC-on-Ethereum cut — distinct from the coin price feeds, the generic ERC-20 token-info feed and the stablecoin feeds. Supplies are in BTC; values in USD (BTC priced from Yahoo Finance). No key, nothing stored beyond a short cache.

The Bitcoin cycle-timing valuation models that tell you whether BTC is historically cheap or expensive right now, computed live and keyless from price (Yahoo Finance daily closes) and on-chain data (the public blockchain.com charts feed). These are not raw time series and not a price feed — they are the derived indicators that on-chain analysts and cycle traders watch to judge where Bitcoin sits between deep value and euphoria. The mayer endpoint returns the Mayer Multiple — price divided by its 200-day moving average — the simplest and most durable over/undervaluation gauge (buying under ~1 and trimming over ~2.4 has historically timed cycles well). The puell endpoint returns the Puell Multiple — daily miner revenue divided by its 365-day average — a miner-side gauge that marks capitulation bottoms (under ~0.5) and tops (over ~4). The nvt endpoint returns the NVT ratio — market cap divided by the 90-day average of on-chain transaction value — Bitcoin's answer to a price/earnings ratio, where a high reading means price is rich relative to the value actually settling on-chain. The s2f endpoint returns the Stock-to-Flow scarcity ratio — circulating supply divided by the realised annual issuance (the flow measured empirically from the supply actually minted over the last 365 days); the S2F price model derived from it is included but clearly flagged as controversial and historically over-optimistic (the response also reports how far the model sits above the actual price). The summary endpoint puts all four side by side with an aggregate cycle read. This is the valuation-model / cycle-indicator cut — distinct from the raw Bitcoin on-chain time-series feeds (which report hashrate, miner revenue and transaction counts but not the derived ratios), the network-security feed (difficulty, hashrate, halving), the block-explorer feed and the crypto-macro correlation feed. Ratios are unitless; model and actual prices are in USD. No key, nothing stored beyond a short cache.

Bitcoin's network-security and mining-economics layer, live and keyless, powered by mempool.space — hashrate, mining difficulty, the difficulty-adjustment countdown, the halving countdown and per-window block-reward economics. These are the numbers that describe how hard Bitcoin is to mine and how secure the chain is, not a price and not a block explorer. The difficulty endpoint is the flagship: the current mining difficulty plus the live adjustment countdown — how far through the current 2016-block epoch we are, the projected size of the next adjustment (Bitcoin retargets every two weeks so blocks stay ~10 minutes apart), the blocks remaining to the retarget, the estimated retarget date and the realised average block time. The hashrate endpoint returns the current network hashrate in EH/s plus a historical hashrate-and-difficulty timeseries over a chosen window (1m to all). The halving endpoint is the countdown to the next block-subsidy halving — the current block height, the current subsidy in BTC, the next halving block and how many blocks and days remain. The rewards endpoint returns block-reward economics over a recent window: the total miner reward, the fee share, and the per-block averages, all in BTC. This is the Bitcoin difficulty / hashrate / halving cut — distinct from the Bitcoin block-explorer feed (mempool, fees, blocks, addresses, transactions), the mining-pool-distribution feed (who finds the blocks and how centralised), and the multi-coin mining-profitability feed. Hashrate in EH/s, difficulty raw and in trillions, rewards in BTC, times in UTC. No key, nothing stored.

One number that tells you whether crypto capital is rotating into altcoins or huddling in Bitcoin, computed live from Binance daily candles (no key, nothing stored). The market swings between two regimes: in "altcoin season" most alts outperform Bitcoin and money chases the long tail; in "Bitcoin season" alts bleed against BTC and capital flees to the majors. The classic gauge is simple — of the top altcoins, what share has outperformed Bitcoin over the last 90 days? Above ~75% it is altcoin season; below ~25% it is Bitcoin season. The index endpoint returns that index (0-100), the season label, Bitcoin's own return over the window and how many alts out- versus under-performed. The leaderboard endpoint ranks the alts by their excess return versus Bitcoin — who is leading the rotation and who is lagging — each with its own return, BTC's return and the gap. The coins endpoint lists the universe. The altcoin-season / alt-vs-BTC rotation cut — distinct from the market-cap-dominance and global-market APIs (which report BTC's share of total cap, not relative performance), the single-coin momentum and the price APIs. It answers whether it is altseason, not what the market cap is.

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.

The long-run on-chain economics of Bitcoin as time series, served from the public blockchain.com charts feed. Where snapshot APIs report the chain state right now, this is the history: how the hash rate, mining difficulty, miners' revenue, daily transaction count, transaction fees, market price, market capitalisation, circulating supply, mempool size, average block size, estimated on-chain transaction volume, daily unique addresses, UTXO count and median confirmation time have moved over months and years. The metric endpoint returns one metric's full daily time series over a chosen window (30 days to all-time) with summary statistics — first, last, change, percent change, minimum, maximum and average. The latest endpoint returns a metric's current value with its change versus the previous reading and versus 30 days ago. The metrics endpoint lists every available metric with its unit and category. This is the historical and charting view of Bitcoin's network economics — distinct from the live mempool-snapshot, the multi-chain network-stats and the price-feed APIs in the catalogue. Live, no key on the upstream, nothing stored.

The value of one bitcoin expressed across every unit CoinGecko tracks — world fiat currencies, precious metals (gold and silver, troy ounce) and other cryptocurrencies, powered by the public CoinGecko exchange-rates feed, no key, nothing stored. This is the "Bitcoin standard" / unit-of-account view: not a coin's dollar price, but how much of each asset one BTC buys right now — 1 BTC in US dollars, euros and yen, in ounces of gold and silver, and in ether, satoshi and dozens more. The rates endpoint returns every unit with its value and asset type; the rate endpoint returns one specific unit (gold, the euro, ether); the groups endpoint splits the units into fiat, commodity and crypto so you can see what a bitcoin is worth across asset classes at a glance. This is the Bitcoin-denominated reference-index cut — distinct from the coin-price converters, the market-overview and the per-exchange ticker APIs in the catalogue.

Live "real" market exchange rates derived from local cryptocurrency (BTC/USDT) trading. Because they are implied by where people actually buy and sell crypto, these rates track the true street/parallel value of a currency — for stressed currencies (Argentine peso, Nigerian naira, Venezuelan bolívar, Lebanese pound …) this is far from the official rate. The rates endpoint returns one base currency against ~130 currencies plus the BTC price; the convert endpoint converts any amount between two currencies; the btc endpoint returns the BTC price in a chosen currency (the crypto bridge that powers every rate); the currencies endpoint lists every supported currency. Read live, nothing stored. This is a global crypto-implied real-rate layer — distinct from official ECB/central-bank rate feeds and from single-country parallel-dollar APIs.

Live data for Bitcoin's Lightning Network — the instant-payment layer on top of Bitcoin — served straight from mempool.space's public API, no key, nothing cached. The stats endpoint returns the state of the whole network: how many nodes and payment channels exist, the total capacity locked in Bitcoin, the average and median channel capacity, the average fee rate, and the split between clearnet and Tor nodes — the network runs tens of thousands of channels holding thousands of BTC. The top endpoint is the node league table, ranked by liquidity (capacity) or by connectivity (channel count), with each node's alias, capacity and channel count — Bitfinex and Binance run some of the largest routing nodes. The search endpoint finds nodes by alias and returns their public key, capacity and channel count. This is the routing-and-liquidity layer for any Lightning wallet, node operator, payment or analytics app — who the big routing nodes are and how much capacity the network holds. Live from mempool.space, nothing stored. Distinct from on-chain Bitcoin and fee APIs — this is the Lightning Network layer. 4 endpoints.

Live Bitcoin halving countdown and supply schedule as an API, computed from the on-chain block height (mempool.space). Bitcoin's block subsidy halves every 210,000 blocks (~four years); this returns the current subsidy in BTC, the halving epoch, the next halving's block height, how many blocks and roughly how long remain (using the network's recent average block time), and the estimated date. It also computes the circulating supply mined to date from the issuance schedule, the percent of the 21-million cap already mined, the daily and annual new issuance and the inflation rate, plus the full halving schedule. The Bitcoin issuance-and-halving layer for crypto, dashboard and countdown apps. Live, no key, no cache. Distinct from fee and mempool Bitcoin APIs — this is the supply and halving schedule.

Live on-chain data for Elastos Smart Chain (ESC) — an EVM sidechain 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 ELA balance, nonce, contract flag and token holdings; transaction resolves a tx by hash with its from/to, value in ELA, 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 ELA, 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).
