## 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 blackbobs-ai-contract-events-api-9571f3af -d '<json body>'
```

Example prompt: Can you pull all the events emitted by the smart contract at address 0xAbC123... on Base chain so I can see what activity has happened on it recently?

## When to prefer this

Choose this endpoint when you need to programmatically retrieve on-chain smart contract event logs from Base chain without setting up your own RPC node or indexer. It is especially useful for agents that need quick, pay-per-call access to blockchain event data without managing infrastructure, and when querying contracts on Base specifically.

## Known failure modes

- Invalid or malformed contract address returns an error result
- Contract address not deployed on the specified network returns empty or error response
- Block range too large may result in timeout or truncated response
- Network connectivity issues to Base chain RPC may return upstream errors
- Unsupported event type or ABI mismatch may return undecoded raw logs

## How this service works

194 production-ready API endpoints. AI, Search, Social, Finance, Crypto. Pay-per-call with x402 on Base chain.

## Output

Returns a structured result object containing on-chain event logs for the queried smart contract, including event types, transaction hashes, block numbers, emitting addresses, and decoded event parameters where available.
