The server completed its last measured handshake. This is an observation, not a guarantee.
Bitcoin: Balance and transaction counts. Supports P2PKH, P2SH, P2WPKH, P2WSH, P2TR and P2A addresses, and P2PK public keys in hex (33 or 65 bytes).
Measured
Bitcoin: Get the newest confirmed transactions for an address, up to `max_txs` (25 by default and at most). For pagination, request `GET /api/address/{address}/txs/chain/{after_txid}` with the last returned txid.
Measured
Bitcoin: Get the next confirmed transactions strictly older than `after_txid`, up to `max_txs` (25 by default and at most); a txid outside the address's history answers `[]` (Esplora-canonical pagination form, matches mempool.space).
Measured
Bitcoin: Find addresses by address type and by the first 1-16 hex nibbles of RapidHash v3 over the raw address payload bytes. Intended for privacy-preserving client-side wallet discovery without sending raw addresses or xpubs. Fetch metadata with `GET /api/address/{address}`.
Measured
Bitcoin: Get unconfirmed transactions for an address from the mempool, newest first, up to `max_txs` (50 by default and at most).
Measured
Bitcoin: Get transaction history for an address, newest first: up to `max_txs` (50 by default and at most), mempool transactions first and confirmed ones filling the rest. To continue, pass the last returned txid as `after_txid`, or request `GET /api/address/{address}/txs/chain/{after_txid}` for confirmed history.
Measured
Bitcoin: Get unspent transaction outputs (UTXOs) for an address, including unconfirmed ones; outputs that mempool transactions spend are left out.
Measured
Bitcoin: Details of a block by hash: height, time, transaction count, size, weight, and difficulty.
Measured
Bitcoin: Find the block with the greatest header timestamp at or before the given UNIX timestamp, choosing the earliest height on ties.
Measured
Bitcoin: Get block fee rate percentiles (min, 10th, 25th, median, 75th, 90th, max) for a time period, each a whole sat/vB (`/precise` for 3 decimals).
Measured
Bitcoin: Get block fee rate percentiles (min, 10th, 25th, median, 75th, 90th, max) for a time period, each in sat/vB to 3 decimals.
Measured
Bitcoin: Get average total fees per block for a time period.
Measured
Bitcoin: Block hash as plain text.
Measured
Bitcoin: Returns the hex-encoded 80-byte block header.
Measured
Bitcoin: Get average coinbase reward (subsidy + fees) per block for a time period.
Measured
Bitcoin: Get average block sizes and weights for a time period.
Measured
Bitcoin: Whether the block is in the best chain and, if so, its height and the hash of the next block. A block outside the best chain (orphaned or unknown) reports `in_best_chain: false`.
Measured
Bitcoin: Hash of the latest block.
Measured
Bitcoin: Height of the latest block.
Measured
Bitcoin: Retrieve a single transaction ID at a specific index within a block. Returns plain text txid.
Measured
Bitcoin: Up to 25 transactions starting at `start_index`, a multiple of 25.
Measured
Bitcoin: Returns block details with extras by hash.
Measured
Bitcoin: The last 10 blocks.
Measured
Bitcoin: Retrieve up to 10 blocks going backwards from the given height. For example, height=100 returns blocks 100, 99, 98, ..., 91. Height=0 returns only block 0. A height past the tip is not found.
Measured
Bitcoin: Retrieve the last 15 blocks with extended data including pool identification and fee statistics.
Measured
Bitcoin: Retrieve up to 15 blocks with extended data going backwards from the given height: the published blocks among the 15 heights ending at it, so fewer (or none) past the tip.
Measured
Bitcoin: Returns ancestors and descendants for a CPFP (Child Pays For Parent) transaction, including the effective fee rate of the package. A mempool transaction answers its live package; a confirmed one its package among its block's transactions; an unknown transaction, or a confirmed one without relatives in its block, `{"ancestors":[]}`.
Measured
Bitcoin: Get current difficulty adjustment progress and estimates.
Measured
Bitcoin: Every difficulty adjustment in the chain's history.
Measured
Bitcoin: Get historical difficulty adjustments for a time period.
Measured
Bitcoin: Same response shape as `GET /api/v1/replacements`, but limited to trees where at least one predecessor was non-signaling (full-RBF).
Measured
Bitcoin: Get network hashrate and difficulty data for all time.
Measured
Bitcoin: Get network hashrate and difficulty data for a time period.
Measured
Bitcoin: Completed four-hour BTC/USD closes, newest first as mempool.space lists them, labeled by interval end, from the first priced interval (2010-08-16). With a UNIX timestamp, returns the latest nonempty completed close at or before it; before the first close returns an empty list. The current partial interval is excluded. USD only (`currency` accepts `USD`); exchangeRates is empty.
Measured
Bitcoin: Current mempool backlog: transaction count, total virtual size, total fees, and fee histogram.
Measured
Bitcoin: Projected blocks for fee estimation, up to eight as mempool.space's. Block 0 is Bitcoin Core's `getblocktemplate` selection; the rest are packed after it as Core's block assembler packs (whole CPFP chunks by feerate, in dependency order, within Core's default weight and sigop budgets), ranked by the node's signed modified fees (including `prioritisetransaction`; mining options shape block 0 only), with paid fees in the statistics. The last holds whatever is left: more than a block when the mempool is busy. `GET /api/mempool-blocks/{index}` serves each with its transactions, except such a last one.
Measured
Bitcoin: Get the last 10 transactions to enter the mempool.
Measured
Bitcoin: Block counts and mining shares by time period for one pool.
Measured
Bitcoin: Get up to 100 recent blocks mined by a specific pool.
Measured
Bitcoin: Get up to 100 blocks mined by a specific pool strictly below the given height (pass the last height of a page to get the next one).
Measured
Bitcoin: Get hashrate history for a specific mining pool.
Measured
Bitcoin: Get mining pool statistics for a time period.
Measured
Bitcoin: Every known mining pool.
Measured
Bitcoin: Get weekly hashrate data, over the whole chain, of the mining pools that mined in the last week, by time and then their weekly rank.
Measured
Bitcoin: Get weekly hashrate data, for a time period, of the mining pools that mined in the last week, by time and then their weekly rank.
Measured
Bitcoin: Recommended fee rates by confirmation target, with up to three decimal places and support for sub-sat/vB rates.
Measured
Bitcoin: Returns bitcoin latest price (on-chain derived, USD only).
Measured
Bitcoin: Returns up to 25 most-recent RBF replacement trees across the whole mempool. Each entry has the shape of `replacements` in `GET /api/v1/tx/{txid}/rbf`.
Measured
Bitcoin: Get mining reward statistics for the last N blocks including total rewards, fees, and transaction count.
Measured
Bitcoin: History of an on-chain metric, by the series id from `search_series`: rows selected by a range of positions, dates or timestamps, as JSON or CSV.
Measured
Bitcoin: Fetch multiple series in a single request. Supports filtering by index and date range. Returns an array of SeriesData objects. For a single series, use `get_series` instead.
Measured
Bitcoin: Returns the number of series available per index type.
Measured
Bitcoin: Returns the optional description, supported indexes, the indexes whose values can be null, the value type, and the optional unit (what the value type measures) for the specified series. The decoded series name is limited to 1024 UTF-8 bytes.
Measured
Bitcoin: Current value of an on-chain metric, by the series id from `search_series`. Returns the value alone, not inside a SeriesData object.
Measured
Bitcoin: Get series data length
Measured
Bitcoin: Returns the vector's schema/computation version, not its length or latest update. Appends and reorgs do not by themselves change this version.
Measured
Bitcoin: Returns a coherent local index snapshot and a separately observed Bitcoin Core tip height. The two heights can differ during indexing or a reorg. Conditional requests refresh these observations before validation.
Measured
Bitcoin: First-seen UNIX timestamps in seconds, in request order, of transactions in the mempool or that recently left it other than by replacement (mined ones included); 0 otherwise.
Measured
Bitcoin: Full details of a transaction by txid: inputs, outputs, fee, size, and confirmation status.
Measured
Bitcoin: Hex-encoded serialized transaction.
Measured
Bitcoin: Merkle inclusion proof of a confirmed transaction in its block.
Measured
Bitcoin: Get the merkleblock proof for a transaction (BIP37 format, hex encoded).
Measured
Bitcoin: Whether the output has been spent and, if so, the spending transaction details. An output no known transaction holds is unspent.
Measured
Bitcoin: Spend statuses in output-index order.
Measured
Bitcoin: Returns the RBF replacement tree for a transaction, if any. Both `replacements` and `replaces` are null when the tx has no known RBF history within the mempool monitor's retention window. A history past 63 versions or 4,096 transactions comes cut to its newest part, its root marked `"truncated": true`.
Measured
Bitcoin: Retrieve the confirmation status of a transaction. Returns whether the transaction is confirmed and, if so, the block height, hash, and timestamp. A transaction not in the chain, pending or unknown, is `{"confirmed":false}`.
Measured
Bitcoin: Retrieve the transaction ID (txid) at a given global transaction index. Returns the txid as plain text.
Measured
Bitcoin: URPD (UTXO realized price distribution: how much supply last moved at each price) for a cohort at a block height or the last block of a UTC day. Returns `{ height, hash, date, cohort, weight, aggregation, close, supply, buckets }` where `buckets` is columns, `{ price, supply, realized_cap, unrealized_pnl }`, one entry per bucket in ascending price: the same block header and columnar layout as `GET /api/utxo-set/{point}`. `close`, `price`, `realized_cap`, and `unrealized_pnl` are USD; `supply` is BTC. `unrealized_pnl` can be negative. Bucket `realized_cap` and `unrealized_pnl` value each coin at its creation price on the price grid (four significant digits of the price in cents, within 0.05% of the exact price), rounded to the cent per bucket, so the buckets need not sum to the realized cap series. With a `wakefulness` or `mobility` `weight`, `supply` is the weighted supply (whole satoshis) and the bucket values follow it.
Measured
Bitcoin: URPD (UTXO realized price distribution: how much supply last moved at each price) for the latest published block; `date` echoes the date served. Fields, units, price-grid rounding and weighting as in `GET /api/urpd/{cohort}/{point}`.
Measured
Bitcoin: What a block (`840000`) or a UTC day's published blocks (`YYYY-MM-DD`) changed in the UTXO set. Returns `{ first, last, hash, date, created, spent }`: `created` has one row per block, `spent` one row per creation height, each as columnar `height`, `count` and `supply` (BTC). The set after block `first - 1` plus `created` minus `spent` is the set after block `last`.
Measured
Bitcoin: Returns every index a series can be read at, by the name series routes take.
Measured
Bitcoin: Paginated flat list of all available series names.
Measured
Bitcoin: Every URPD cohort once a UTXO set is published (none before): the age aggregates (`all`, `sth`, `lth`, `age_under_4m`, ...), then the age bands from the youngest (`age_under_1h`, `age_1h_to_1d`, ...).
Measured
Bitcoin: Find on-chain metrics by plain words: MVRV, realized price, SOPR, NUPL, supply held by long-term or short-term holders, coin age, addresses by balance, hashrate, fees, volume, and thousands more. Start here for any metric question: it returns the series ids to pass to `get_series_latest` or `get_series`. Results prioritize whole query words in names, then descriptions, then fuzzy names, then fuzzy descriptions. Word order does not matter. Descriptions provide cohort terminology and formulas. The decoded q parameter is limited to 1024 UTF-8 bytes.
Measured
Bitcoin: Validate a Bitcoin address and get information about its type and scriptPubKey. Returns `isvalid: false` with an error message for invalid addresses; a string that isn't 2 to 130 letters and digits answers 400.
