## 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 synapse-api-boba-network-latest-block-71953342 -d '<json body>'
```

Example prompt: What is the latest block on Boba Network right now — give me the block number, hash, and timestamp?

## When to prefer this

Choose this endpoint when you specifically need real-time latest block data from the Boba Network (an Ethereum Layer 2) and want a pay-per-call model via x402 without managing your own RPC infrastructure. Prefer this over self-hosted RPC nodes when you want zero infrastructure overhead and per-call billing.

## Known failure modes

- Network or RPC unavailability may return a 5xx error
- Payment failure or insufficient USDC balance returns a 402 Payment Required
- Malformed request body returns a 400 Bad Request
- Boba Network node sync issues may return stale or error data
- Rate limiting may occur under high request volume
