# Bitcoin Transaction Status

> Bitcoin Transaction Status is a paid API for AI agents from bess-x402.onrender.com, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-30).

Looks up the status of a Bitcoin transaction by txid, returning confirmation count, block info, fee, fee rate, RBF flag, and inputs/outputs.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability bitcoin-transaction-status-6adb1a6a
```

Example prompt: Can you check whether my Bitcoin transaction is confirmed yet? The txid is 4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b — also tell me how many confirmations it has and what the fee rate was.

## When to prefer this

Use this endpoint when you need authoritative Bitcoin transaction details — confirmation status, fee analysis, or RBF eligibility — for a specific txid. Prefer this over generic block explorers when you need structured JSON data suitable for agent decision-making (e.g. auto fee-bumping logic or payment verification workflows). For EVM chains, use the sibling EVM Transaction Status endpoint instead.

## Known failure modes

- Invalid or malformed txid (not 64 hex characters) returns a validation error
- Transaction not found on the Bitcoin network returns a not-found error
- Network or node connectivity issues may result in timeout or service unavailable
- Very recently broadcast transactions may not yet be visible if mempool propagation is incomplete

## How this service works

Status of a Bitcoin transaction: confirmed or pending, confirmations, block, time, fee and fee rate, RBF flag, inputs and outputs. Use to confirm a BTC payment or decide whether to bump a fee.

## Output

Returns whether the transaction is confirmed or pending, the number of confirmations, the block it was included in, the timestamp, the total fee in satoshis, the fee rate (sat/vbyte), whether RBF (replace-by-fee) is flagged, and a breakdown of inputs and outputs.
