How this service works
Bitcoin transaction lookup: inputs and outputs with types, fee and fee rate, confirmations, block time and RBF signalling, from Bitcoin Core RPC.
Output
A JSON object containing: chain identifier, txid, confirmed status, confirmation count, input and output arrays (with types), input count, output count, total input satoshis, total output satoshis, fee in satoshis, fee rate in sat/vB, block hash, block time (UTC), vsize, weight, size in bytes, RBF replaceable flag, coinbase flag, and a note about how to interpret the result along with the data source.
Example use cases
Confirm payment received on-chain
“I need to verify that Bitcoin transaction f4184fc596403b9d638783cf57adfe4c75c605f6356fbc91338530e9831e9e16 has been confirmed — can you check how many confirmations it has and when the block time was?”
Audit transaction fee for cost analysis
“Can you pull the fee in satoshis and fee rate in sat/vB for Bitcoin transaction b6f6991d03df0e2e04dafffcd6bc418aac66049e2cd74b80f14ac86db1e3f723? I want to know if we overpaid.”
Inspect transaction inputs and outputs
“Look up Bitcoin transaction d5d27987d2a3dfc724e359870c6644b40e497bdc0589a033220fe15429d88599 and show me all the inputs, outputs, and their types so I can reconstruct what happened.”
Technical details
Endpoint
GEThttps://saylorinnovations.com/api/explorer/bitcoin/tx?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need detailed, structured Bitcoin transaction data including inputs, outputs, fees, fee rates, RBF status, and confirmation count sourced directly from Bitcoin Core RPC. Prefer it over block explorer scraping when you need machine-readable JSON with typed output, or when you need RBF signalling and fee-rate data in a single call. It is best suited for single-transaction lookups rather than bulk analysis.
Side effects
- Invalid or malformed txid (not 64 hex characters) returns an error
- Transaction not found on the Bitcoin network returns a not-found response
- Unconfirmed mempool transactions may have null fee/block fields
- Bitcoin Core RPC node downtime may cause service unavailability
- Very recent transactions may not yet be visible to the node
