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 openrelay-tx-status-bd6d44b8 -d '<json body>'
```

Example prompt: Can you check if my Base transaction 0x4a3b...c91d has been confirmed yet — I need to know the status, which block it landed in, and whether it errored out.

## When to prefer this

Use this endpoint when an AI agent needs to programmatically verify whether a specific Base or Solana transaction has been confirmed, retrieve its block/slot number, or diagnose a transaction failure — especially in payment verification workflows or post-swap confirmation checks where a quick, cheap per-call lookup is needed.

## Known failure modes

- Invalid or malformed transaction hash returns an error
- Unsupported chain value (not 'base' or 'solana') rejected by enum validation
- Transaction not yet indexed returns pending or not-found status
- Network or RPC timeout causes delayed or failed lookup
- Payment failure (insufficient USDC balance) blocks the request

## How this service works

Check transaction status on Base or Solana. Returns confirmed, status, block/slot, gas, err.

## Output

Returns a JSON object containing: confirmation status (e.g. confirmed/pending/failed), block number or slot, gas used, and any error details associated with the transaction.
