Cardano Transactions API

The Transactions API returns transaction-level data on Cardano: input and output totals, fees in ADA and USD, mint counts, withdrawals, and block context. Use it for daily reporting, fee analysis, spotting outlier transactions, and building activity dashboards.

Endpoint

Cardano GraphQL queries are served at https://graphql.bitquery.io.

Get Cardano transactions for a specific date​

Pull 10 transactions from a single day with full economic context — input value in ADA and USD, fee value in ADA and USD, mint count, withdrawal totals, output value, and input/output counts.

{
  cardano(network: cardano) {
    transactions(options: {limit: 10}, date: {is: "2023-11-29"}) {
      block {
        timestamp {
          time(format: "%Y-%m-%d %H:%M:%S")
        }
        height
      }
      hash
      index
      inputValue
      input_value_usd: inputValue(in: USD)
      outputValue
      inputCount
      outputCount
      feeValue
      fee_value_usd: feeValue(in: USD)
      mintCount
      withdrawalValue
      withdrawalCount
    }
  }
}

Switch date: {is: ...} to date: {since: ..., till: ...} for a range, sort with options: {desc: ["block.height", "index"], limit: 10} to pull the latest, or add feeValue: {gt: ...} to surface high-fee transactions only.

Count daily Cardano transactions​

Aggregate the total transaction count per day for the last 10 days. Useful for activity dashboards, throughput monitoring, and spotting unusual spikes.

{
  cardano(network: cardano) {
    transactions(options: {desc: "date.date", limit: 10}) {
      date {
        date
      }
      count
    }
  }
}

Use startOfInterval(unit: day, interval: 10) for coarser buckets, raise limit for more days, or add a date: {since: ..., till: ...} window.
