## 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-user-fees-lookup-20847773
```

Example prompt: Pull the last 20 user fee records from Beggar Bot on Base mainnet so I can see what fees have been charged recently.

## When to prefer this

Use this endpoint when you need a paginated list of user fee records collected on Base mainnet (or base-sepolia) via the Beggar Bot system, particularly for auditing, monitoring, or reporting on fee activity. Prefer this over /v1/verify or /v1/risk when your goal is historical fee data rather than verifying a specific transaction or assessing risk.

## Known failure modes

- Invalid chain name returns an error or empty result
- Limit parameter out of acceptable range may be ignored or cause an error
- Payment not fulfilled (402) if the $0.02 USDC x402 payment is not provided
- Rate limiting or quota exceeded on the Cloudflare Worker
- Network timeout if Base mainnet RPC is slow to respond

## How this service works

Paid: /v1/verify, /v1/risk, /v1/receipt cost $0.01 USDC per call on Base mainnet via x402 (payTo 0x719227f384b66BFEF00093D6d8d32fA9dC2B40e7); utilities analyze Base mainnet (USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) by default, network=base-sepolia optional; /v1/receipt/verify and discovery files are free. Operator: Beggar Bot.
