## 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 phantom-api-bnb-latest-block-b40646a9 -d '<json body>'
```

Example prompt: What's the latest block on BNB Smart Chain right now — give me the block number, hash, and timestamp?

## When to prefer this

Choose this endpoint when you need real-time, pay-per-call access to the latest BNB Smart Chain block without managing your own RPC node or API key subscription. It is ideal for lightweight agents that make occasional queries and want to avoid monthly subscription costs, leveraging x402 micropayments for on-demand blockchain data access across BNB specifically.

## Known failure modes

- Payment not received (402 response if x402 payment header is missing or invalid)
- Network congestion may cause momentary delays in data freshness
- BNB chain RPC node downtime returns 5xx errors
- Rate limiting if too many calls made in short succession
- Empty or malformed response if the chain is undergoing a halt or fork
