## 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-solana-block-lookup-6f0e152c -d '<json body>'
```

Example prompt: Can you look up the details for Solana block number 295000000 — I want to see the transactions and metadata in that block?

## When to prefer this

Use this endpoint when you need to look up a specific Solana block by integer block ID and retrieve its full metadata and transactions. Prefer this over general blockchain explorers when you need programmatic, agent-accessible access with pay-per-call pricing and no API key setup. Best suited for Solana-specific block inspection; sibling endpoints on the same gateway cover Bitcoin, Bitcoin Cash, and Ethereum.

## Known failure modes

- Invalid or non-existent block ID returns an error response
- Network field mismatch (e.g. wrong chain) may return empty or error
- Block not yet finalized may not be available
- Payment failure (402) if USDC payment not properly attached
- Rate limiting or service unavailability returns 5xx errors
