## 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 ddg-base-blockchain-log-fetcher-9adf3993 -d '<json body>'
```

Example prompt: Can you pull the recent event logs from the Base blockchain for contract 0xABC...123 — I need to see what's happened in the last 10,000 blocks, up to 5,000 results.

## When to prefer this

Choose this endpoint when you need recent, raw event logs specifically from the Base (Coinbase L2) blockchain and want a pay-per-call model without managing your own RPC infrastructure. It is well-suited for agent workflows that need on-demand log retrieval without a subscription, especially when querying within a recent 10,000-block window. Prefer alternatives if you need historical data beyond 10,000 blocks, need logs from other chains, or require WebSocket-based streaming.

## Known failure modes

- Invalid or malformed contract address returns an error response
- Filter criteria too broad may hit the 5,000-result cap and return a truncated set
- Block range exceeding 10,000 blocks will be rejected or capped
- Payment failure (402) if USDC balance is insufficient
- Malformed JSON body causes request rejection
- Base RPC node unavailability may cause timeouts or 503 errors

## How this service works
