## 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-pm-book-lookup-base-mainnet-e4934a60
```

Example prompt: Pull up the payment book record from Beggar Bot for Base mainnet — I want to see what's logged there for the default USDC contract.

## When to prefer this

Use this endpoint when you need to retrieve payment book or PM ledger records specifically tracked by the Beggar Bot service on Base mainnet, and you are prepared to pay $0.02 USDC per call via the x402 micropayment protocol. Prefer this over /v1/verify or /v1/risk when you need raw ledger/book data rather than verification or risk scoring.

## Known failure modes

- Payment required (402): call will fail if $0.02 USDC is not provided via x402 to the specified payTo address
- Invalid properties parameter returns malformed or empty JSON
- Network mismatch if base-sepolia is specified but mainnet data is requested
- Rate limiting or Cloudflare Worker timeouts under high load
- Empty result if no pmbook entries exist for the queried address
