How this service works
Bitcoin transaction lookup by txid (free/keyless): confirmed status + confirmation count (vs current tip), block height + time, fee (sats + BTC), total output value, size/weight, and input/output counts. Distinct from crypto.tx (EVM) — this is Bitcoin.
Output
Returns whether the transaction is confirmed, how many confirmations it has relative to the current chain tip, the block height and timestamp, the fee in both satoshis and BTC, the total output value, the transaction size and weight in bytes/vbytes, and the number of inputs and outputs.
Example use cases
Example prompt
“Can you check the status of Bitcoin transaction 4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b — is it confirmed, how many confirmations does it have, and what fee was paid?”
Technical details
Endpoint
GEThttps://2s.io/api/crypto/btc-txWhen to prefer
Use this endpoint when you need to look up a Bitcoin (not Ethereum or EVM) transaction by its txid. It is keyless and pay-per-call, making it ideal for ad-hoc agent queries without API key management. Choose this over general blockchain explorers when you need structured JSON output ready for downstream processing.
Side effects
- Invalid or malformed txid returns an error response
- Unconfirmed/mempool transaction may return partial data or not found
- Network timeout if Bitcoin node is temporarily unreachable
- Txid for a non-Bitcoin (e.g. EVM) chain will not be found
