## 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 money-reactor-base-block-number-6c3dc17f
```

Example prompt: What is the current block number on Base right now? I need the exact block height and timestamp.

## When to prefer this

Choose this endpoint when you need a quick, no-account, pay-per-call lookup of the current Base block number without setting up API keys or managing subscriptions. Ideal for AI agents that need occasional block-height checks rather than continuous websocket feeds.

## Known failure modes

- RPC node unavailability — returns an error if the underlying Base RPC is unreachable
- Payment failure — x402 payment not settled, request rejected before reaching the endpoint
- Rate limiting — excessive requests may be throttled
- Stale data — in rare cases the node may lag behind the true chain head
