## 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-ronin-latest-block-bc1920a8 -d '<json body>'
```

Example prompt: What is the latest block on the Ronin blockchain 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 Ronin blockchain (Axie Infinity's sidechain) and want a pay-per-call model via x402 without managing RPC node infrastructure. Prefer alternatives if you need historical block data, blocks from other EVM chains, or bulk/batch block queries.

## Known failure modes

- Network or RPC node downtime may cause timeout or 5xx errors
- Payment not included or insufficient USDC may result in 402 Payment Required response
- Ronin network itself may be halted or lagging, returning stale data
- Invalid or malformed request body may return 400 Bad Request
- Rate limiting may apply if too many calls are made in quick succession
