## 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 vextorium-bitcoin-transaction-status-fd90395b -d '<json body>'

Example prompt: Can you check whether Bitcoin transaction 4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b is confirmed, how many confirmations it has, what block it landed in, and what the fee rate was in sat/vB?

## When to prefer this

Use this endpoint when you need complete Bitcoin transaction details from a single txid — confirmation status, fee breakdown, RBF flag, and full input/output breakdown — sourced from Blockstream Esplora. Prefer it over generic block explorer scraping when you need structured JSON output ready for agent processing.

## Known failure modes

- Invalid or malformed txid returns an error or null result
- Transaction not found on chain or mempool returns empty/null
- Network or node unavailability causes timeout or 5xx error
- Very recent unconfirmed transactions may not yet appear in mempool data
