## 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 crypto-shark-bazaar-chain-confirmation-status-70f4bcd6
```

Example prompt: Can you check the confirmation status of my transaction on the Base network and tell me when it was observed and whether it's been confirmed on-chain?

## When to prefer this

Choose this endpoint when you need a low-cost ($0.001 USDC), real-time lookup of on-chain confirmation status specifically on the Base network, and you are operating within an x402-compatible agent payment workflow. Prefer it over heavier blockchain explorer APIs when you only need confirmation status rather than full transaction details.

## Known failure modes

- Missing or invalid transaction/block identifier returns an error or empty result
- Transaction not yet indexed returns unconfirmed or null status
- Network unavailability or node lag may return stale observation timestamps
- Malformed properties input returns a 400-level error
- Rate limiting or payment failure via x402 returns a 402 Payment Required response

## How this service works

Low-cost x402 blockchain primitives, market intelligence, and AI utilities for autonomous agents

## Output

Returns a JSON object indicating the network name (e.g. 'base'), the observed timestamp of the transaction or block, and confirmation status details as of the observation time.
