How this service works
Bitcoin transaction details - confirmations, block, fee and fee rate, inputs and outputs
Output
Returns a JSON object with: found (boolean), confirmed (boolean), txid, block height, block time, transaction size in bytes, weight, fee in satoshis, fee rate in sat/vbyte, number of inputs, number of outputs, total output BTC, and the data source. Returns found=false if the txid does not match any known transaction.
Example use cases
Verify incoming Bitcoin payment
“I just received a Bitcoin payment — can you check txid f4184fc596403b9d638783cf57adfe4c75c605f6356fbc91338530e9831e9e16 and confirm it's been included in a block and tell me how many confirmations it has?”
Audit fee paid on a Bitcoin transfer
“What fee and fee rate in sat/vbyte did we pay for Bitcoin transaction 0e3e2357e806b6cdb1f70b54c3a3a17b6714ee1f0e68bebb44a74b1efd512098?”
Investigate Bitcoin transaction structure

Technical details
Endpoint
GEThttps://saylorinnovations.com/api/btc/tx/:txid?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need structured, fee-inclusive Bitcoin transaction details from a single txid lookup, especially when you need fee rate, block confirmation status, and input/output counts in one call. Prefer this over raw blockchain node RPC when you want a simple REST API with a flat JSON response. Suitable for payment verification, fee auditing, and on-chain analytics workflows.
Side effects
- Invalid txid format (not 64 hex characters) — likely returns error or found=false
- Transaction not yet broadcast or not indexed — returns found=false
- Unconfirmed mempool transaction — confirmed=false, block fields null
- Network or upstream data source unavailable — server error response
- Malformed txid (wrong length or non-hex characters) — request rejection
