## 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 explorer-gateway-api-ethereum-recent-blocks-c50a3711 -d '<json body>'
```

Example prompt: Can you pull the last 10 recent Ethereum blocks from Blockchain.info's explorer gateway so I can see what's been confirmed on-chain?

## When to prefer this

Use this endpoint when you need a quick, paginated list of recent Ethereum blocks from a well-known blockchain explorer (Blockchain.com) without running your own node. Ideal for dashboards, monitoring agents, or analytics pipelines that need recent on-chain block data without complex RPC setup. Prefer this over raw node RPC if you want a simple REST interface with predictable JSON output.

## Known failure modes

- limit value above 20 is silently capped at 20
- limit of 0 is treated as 1, not an empty result
- invalid network identifier returns an error or empty response
- missing network parameter may default or fail
- rate limiting may occur under high frequency calls
- payment failure (x402 protocol) blocks the request
