## 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 beggar-bot-solana-block-range-lookup-c5e1c22e
```

Example prompt: Can you fetch the last 200 Solana slots starting from slot 280000000 using the Beggar Bot block range API?

## When to prefer this

Use this endpoint when you need programmatic access to a contiguous range of Solana slots and are comfortable paying $0.02 USDC per call via x402 micropayment on Base. Prefer this over free Solana RPC endpoints when you need a simple, agent-friendly REST interface without managing WebSocket connections or JSON-RPC formatting.

## Known failure modes

- Payment not sent or insufficient USDC balance causes 402 Payment Required response
- Invalid or future start_slot returns empty range or error
- limit exceeding 1000 is rejected or clamped
- Network connectivity issues to Cloudflare Workers returns 5xx
- Requesting slots far in the past may return incomplete data
