## 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 scriptmasterlabs-acp-x402-transaction-status-api-99911192
```

Example prompt: Can you check the status of my Base network transaction — the hash is 0xabc123... — and tell me if it's confirmed or still pending?

## When to prefer this

Use this endpoint when you need to verify the confirmation status of a specific on-chain transaction on the Base network, especially in the context of x402 micropayment flows or USDC settlements. Prefer this over a generic block explorer scrape when you need a pay-per-call programmatic API response suitable for agent workflows.

## Known failure modes

- Invalid or malformed transaction hash returns an error
- Transaction not found on the Base network returns 404 or empty result
- Network congestion may cause delayed status updates
- x402 payment failure (insufficient USDC balance) blocks the call
- Service may be slow or unavailable due to Render.com cold starts

## How this service works

Pay-per-call crypto, RWA, federal, SEC, and compliance APIs. Settled in USDC on Base via x402. Hyphen routes only (e.g. /x402/rwa-aggregates, /x402/gas-tracker).

## Output

Returns the current status of a specified blockchain transaction on the Base network, including whether it is pending, confirmed, or failed, along with relevant transaction metadata.
