## 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 manylives-onchain-chain-events-5a8a1aaf
```

Example prompt: Pull the last 20 blocks of Transfer events for the contract at 0x4200000000000000000000000000000000000006 on the Base network so I can see recent token movement.

## When to prefer this

Choose this endpoint when you need on-chain event data (transfers, approvals, or custom log topics) for a specific Base network contract without setting up your own blockchain node or indexer. It is ideal for AI trading agents that need pay-per-call access to verifiable on-chain activity without subscription commitments. Prefer this over generic blockchain explorers when you need structured JSON output ready for agent consumption and are already operating within the ManyLives ecosystem for crypto strategy signals.

## Known failure modes

- Missing required 'address' parameter returns a validation error
- Invalid or malformed 0x contract address returns an error response
- Requested block range exceeds maximum of 1000 blocks
- Contract has no events of the requested type in the scanned range, returning empty events array
- Payment of 0.005 USDC not completed results in HTTP 402 and no data returned
- Unsupported event type string returns an error or empty result

## How this service works

Pay-per-call tools for people building AI agents: live web search and page contents, point-in-time crypto market data and news for backtests (no lookahead), verifiable track records of 1,000 crypto strategies locked on the Base network, company profiles, quick AI and batch prices. Ask us to turn a public website into a JSON endpoint. Pay per call, no account, free trial.

## Output

Returns a JSON object containing an array of on-chain events for the queried contract, each with fields: event name, transaction hash, from address, to address, block number, and raw amount. Also includes the queried contract address and the from/to block range scanned.
