Transaction API

The Bitcoin Transaction API returns detailed transaction data including inputs, outputs, fees, block context, and USD values. Works with query variables for flexible pagination and date filtering.

Get Latest Bitcoin Transactions with Fees and Transfer Values​

query ($network: BitcoinNetwork!, $limit: Int!, $offset: Int!, $from: ISO8601DateTime, $till: ISO8601DateTime) {
  bitcoin(network: $network) {
    transactions(
      options: {desc: ["block.height", "index"], limit: $limit, offset: $offset}
      time: {since: $from, till: $till}
    ) {
      block {
        timestamp {
          time(format: "%Y-%m-%d %H:%M:%S")
        }
        height
      }
      inputValue
      input_value_usd: inputValue(in: USD)
      outputCount
      inputCount
      index
      hash
      feeValue
      fee_value_usd: feeValue(in: USD)
    }
  }
}

Fetch the latest Bitcoin transactions with input/output values in BTC and USD, fee amounts, and block context. Uses query variables for limit, offset, and date range — a reusable pattern for paginated transaction feeds.

Variations: Adjust limit and offset for pagination. Narrow with inputAddress or outputAddress for a specific wallet. Add hash: {is: "..."} for a single transaction lookup.

Daily Bitcoin Transaction Count and Average Fee per Day​

query ($network: BitcoinNetwork!, $dateFormat: String!, $from: ISO8601DateTime, $till: ISO8601DateTime) {
  bitcoin(network: $network) {
    transactions(options: {asc: "date.date"}, date: {since: $from, till: $till}) {
      date: date {
        date(format: $dateFormat)
      }
      count: countBigInt
      feeValue
      avgFee: feeValue(calculate: average)
    }
  }
}

Get daily transaction counts and average fees over a date range. Returns count, total fees, and average fee per day — useful for fee trend analysis and network health dashboards.

Variations: Change the date variables for different periods. Add feeValue(calculate: median) for median fees. Use count(uniq: addresses) for daily active address counts alongside fee data.

List Bitcoin Transactions Sent from a Specific Address​

query ($network: BitcoinNetwork!) {
  bitcoin(network: $network) {
    transactions(
      options: {desc: ["block.height"]}
      inputAddress: {is: "bc1p4kufll9uhnpkgzuc65slcxd2qaw2hl9xecket3h8yyu4awglcsqslqaztd"}
    ) {
      block {
        timestamp {
          time(format: "%Y-%m-%d %H:%M:%S")
        }
        height
      }
      inputValue
      hash
      feeValue
      outputValue
    }
  }
}

List all transactions where a specific address was an input (sender). Returns input values, output values, fees, and block timestamps — the standard query for viewing a Bitcoin wallet's outbound transaction history.

Variations: Switch to outputAddress for received transactions. Add date for a time range. Use limit/offset for pagination. Add value(in: USD) for USD-equivalent amounts.
