## 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 receiptvault-transaction-status-on-base-6187036e
```

Example prompt: Did transaction 0x3a1f...c4b2 succeed on Base? I need to know the status, block number, and how much gas was used.

## When to prefer this

Choose this endpoint when you need a real-time, uncached, direct read of a transaction's status on Base — especially to confirm payments, verify smart contract calls, or audit gas costs. Prefer it over cached or aggregator alternatives when freshness and accuracy are critical. Ideal for agents that need to verify on-chain activity as part of an automated workflow.

## Known failure modes

- Invalid or malformed hash (not 0x-prefixed or not 64 hex chars) returns an error
- Transaction hash not found on Base (wrong network or hash) returns not-found error
- Node connectivity issues may cause timeout or unavailability
- Pending transactions (not yet mined) may return no result or pending status
