## 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 ggwp-api-hub-contract-events-1620aba5 -d '<json body>'
```

Example prompt: Can you pull the recent contract events for this Base chain smart contract address — I want to see what transactions or interactions have been logged on-chain?

## When to prefer this

Choose this endpoint when you need pay-per-call, on-demand access to smart contract events on the Base chain without committing to a subscription. It is suitable for agents that need occasional blockchain event lookups billed via x402 micropayments in USDC rather than maintaining a dedicated node or indexer subscription.

## Known failure modes

- Invalid or malformed contract address returns an error or empty result
- No events found for the given block range or filters returns empty data
- Payment failure via x402 protocol on Base chain blocks the request
- Rate limiting or quota exceeded returns a payment or access error
- Vercel cold-start latency may increase response times for infrequent calls
- Malformed input object schema may return a generic API error
