Blockchair

Cryptocurrency

Read any of 18 blockchains through one integration. Blockchair is a multi-chain explorer, so the same steps answer for Bitcoin, Ethereum, Litecoin, Dogecoin, Monero, Cardano, XRP and the rest: look up an address's balance and history, follow a transaction until it confirms, read a block, or check thousands of addresses in one cheap request. Balances come back both as satoshi or wei and as a readable coin amount, and every lookup reports how many confirmations it has. Beyond the lookups it answers the analytical questions most explorers cannot: filter, sort and total the blocks, transactions, outputs and token transfers tables the way you would query a database, watch every balance a block moved without polling addresses one by one, read a whole watch-only wallet from its xpub, and check a portfolio across chains in a single call. Also carries crypto news from 60+ outlets, node-software release tracking and halving countdowns. Every action is read-only: nothing here can move coins or change a blockchain. Works with no account and no API key on the free plan; a Premium key raises the limits.

Steps your workflow can run in Blockchair.

Get blockchain statsGet a snapshot of one blockchain right now: its height, how many transactions it carried in the last 24 hours, what is waiting in the mempool, the suggested fee, the difficulty and the coin's price and market cap. Covers all 18 chains Blockchair indexes, from Bitcoin and Ethereum to Monero, Cardano and XRP. No API key required.

Get stats for all blockchainsGet the same snapshot for every blockchain Blockchair indexes, in one request: height, 24-hour activity, price, market cap and market dominance for all 18 chains. This is the one call behind a multi-chain status board or a daily market digest. No API key required.

Get stablecoin statsGet a stablecoin's total supply, 24-hour volume and transfer count added up across every blockchain it is issued on. Tether, USD Coin and Binance USD each run on several chains at once, so this is the number to report rather than the supply on any one of them. No API key required.

Get a blockLook up one block, or up to ten at once, by height or by hash. Reports when it was mined, its size, who mined it, the fees and reward it paid, how many confirmations it has now, and the hashes of the transactions inside it. Works on every Bitcoin-like chain and on Ethereum. No API key required.

List blocksQuery the blocks table: the latest blocks, every block in a date range, the largest block of a month, or blocks from one mining pool. Can also group and total instead of listing, so one call answers 'how many blocks did each pool mine last month'. No API key required.

Get raw block dataGet a block exactly as the chain's own node reports it, without Blockchair's tidying. This is the only block lookup for the chains with no dashboard of their own - XRP and Stellar (where it is a ledger), Monero, Cardano, Mixin (a snapshot), Tezos and EOS - and is also available for Bitcoin and Ethereum when a field Blockchair does not surface is needed. No API key required.

Get a transactionLook up one transaction, or up to ten at once, by hash. Reports its value, fee, size, how many confirmations it has, and every input and output with the addresses on each side - or, on Ethereum, the internal calls and the ERC-20 transfers it made. Finds transactions that are still in the mempool too, which is how a workflow watches a payment land. No API key required.

List transactionsQuery the transactions table: the newest transactions, everything over a value in a date range, or the largest transfer of the day. Switch to the mempool to see what is waiting to confirm right now. Can also group and total instead of listing, so one call answers 'what were the average fees by day last month'. No API key required.

Get raw transaction dataGet a transaction exactly as the chain's own node reports it. This is the only transaction lookup for the chains with no dashboard of their own - XRP, Stellar, Monero, Cardano, Mixin, Tezos (where it is an operation) and EOS - and is also available for Bitcoin and Ethereum when the raw script or witness data is what is needed. No API key required.

Get an addressLook up a wallet address: what it holds now, what it has ever received and spent, when it was first and last used, its recent transactions with the balance change each one caused, and its unspent outputs. On Ethereum it also reports the account's ERC-20 token balances. Balances come back both as satoshi or wei and as a readable coin amount. No API key required.

Get an address setTreat up to 100 addresses as one wallet: a combined balance, a per-address breakdown, and one merged list of the newest transactions across all of them. This is what to use for a wallet that spreads across many addresses, rather than looking each one up and adding the numbers together. Bitcoin-like chains only. No API key required.

Get an extended public key (xpub)Read a whole watch-only wallet from its extended public key. Blockchair derives the addresses itself and reports the wallet's total balance, every derived address that has been used with its derivation path, and one merged transaction history - so a workflow can watch a hardware wallet without ever listing its addresses. Takes xpub, ypub and zpub keys. No API key required.

Check many address balancesCheck the confirmed balance of a long list of addresses in one cheap, fast request - up to 25,000 of them. This is the endpoint for polling a watch list or auditing cold storage: 25,000 addresses cost 26 request points against one point per address anywhere else. Addresses holding nothing are reported separately rather than silently dropped. Bitcoin-like chains only. No API key required.

Check addresses across blockchainsCheck addresses on several different blockchains in one request and get the whole holding's value in USD. Write each one as chain:address - bitcoin:1A1z..., ethereum:0xd8dA... - and Blockchair adds them up across chains. This is the portfolio check: one call instead of one per chain. No API key required.

List richest addressesQuery the rich list: every address on a chain with its confirmed balance, biggest first. Filter by balance to count the addresses over a threshold, or page through the top holders. Balances come back both as satoshi or wei and as a readable coin amount. No API key required.

Get raw account dataGet an account exactly as the chain's own node reports it. This is the address lookup for the account-based chains Blockchair indexes without a dashboard of their own: XRP, Stellar, Cardano, Tezos and EOS. For Bitcoin-like chains and Ethereum, use Get an address instead. No API key required.

Get state changesList every address a block moved coins for, and by how much. This is how a workflow watches thousands of addresses without polling each one: read the changes a block caused and look for the addresses that matter. Switch to the mempool to see the changes that are about to happen. No API key required.

List transaction outputsQuery individual coin movements on a UTXO chain - the finest detail Blockchair publishes. One row per coin sent, with the address that received it, its value, whether it has since been spent and how long it sat unspent. Use it to find every payment to an address in a period, or every OP_RETURN message in a month. No API key required.

List Ethereum callsQuery Ethereum's internal calls: the value moves that happen inside a transaction rather than at its top level. This is where a contract paying out or a wallet sweeping funds actually shows up, and it is the only way to see ETH that moved without a transaction of its own. No API key required.

List Ethereum unclesQuery Ethereum's uncle blocks: valid blocks that lost the race to be included, and the reduced reward they still earned. Historical data, since Ethereum stopped producing uncles when it moved to proof of stake. No API key required.

Get an Ethereum uncleLook up one Ethereum uncle block, or up to ten at once, by hash: which block adopted it, who mined it, and what reward it paid. Get a block reports a block's uncle hashes, which is where these come from. No API key required.

Get an ERC-20 tokenLook up an ERC-20 token by its contract address: its name, symbol, decimals, circulating supply, 24-hour transfer volume and price. Any token on Ethereum, not just the well-known ones. No API key required.

Get a token balanceCheck how much of one ERC-20 token a wallet holds, and list its transfers of that token. This is the check for a payment in USDT or USDC: point it at the token's contract and the wallet, and read the balance and the newest transfers. No API key required.

List ERC-20 tokensQuery Ethereum's token registry: the newest tokens deployed, or a search by name or symbol across all 1.5 million of them. Useful for finding a token's contract address from its ticker before checking a balance. No API key required.

List ERC-20 transfersQuery ERC-20 token transfers: every movement of one token, everything one wallet sent or received, or the largest stablecoin transfers of the day. Each row names the token, the sender, the recipient and the amount. No API key required.

Get Omni Layer statsGet the totals for Omni Layer, the token protocol that runs on top of Bitcoin and originally issued Tether: how many tokens exist on it and how much they have moved. No API key required.

Get an Omni Layer tokenLook up one token issued on Omni Layer by its property id: its name, issuer, description, supply and the Bitcoin transaction that created it. Property 31 is the original TetherUS. No API key required.

List Omni Layer tokensQuery every token issued on Omni Layer, with its id, name, issuer and supply. This is where a property id comes from before looking one up in detail. No API key required.

List network nodesSee who is running the network: how many full nodes are online, which countries they are in, which software versions they run and which block they are on. Pick a blockchain to get the individual nodes too, or leave it blank for the counts across all eight crawled chains at once. No API key required.

Get indexed block rangesFind out how far back Blockchair's history goes on each chain. Most are indexed in full from the genesis block, but a few are only indexed from a later block onwards - worth checking before a workflow asks for an old block and gets nothing back. No API key required.

List node software releasesGet the latest node-software release for each blockchain, newest first, with its version, publish date and GitHub link. This is what a scheduled workflow watches to hear about a hard fork before it happens - a new tag here is the upgrade an exchange or wallet has to ship. No API key required.

Get halving countdownGet the countdown to the next block-reward halving on each proof-of-work chain: how many blocks are left, roughly when it lands, and what the reward becomes. Everything a countdown post or a scheduled reminder needs. No API key required.

List crypto newsGet crypto headlines from more than 60 outlets in 14 languages, newest first, each with its source, summary, publish time and a link to the article. Search by keyword across headlines and summaries, filter to one language, one outlet or a date range. This is the feed behind a daily digest or a brand-mention alert. No API key required.
