Checks USDC paycheck/balance status for a given wallet address across multiple chains, returning payment-related data for that address.

## 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-paycheck-endpoint-base-mainnet-3e18a39c
```

Example prompt: Can you check the paycheck status for wallet 0x1234567890abcdef1234567890abcdef12345678 and see if it's received any USDC across the default 5 mainnets?

## When to prefer this

Use this endpoint when you need to query USDC paycheck or payment receipt status for a specific wallet address on Base mainnet or other EVM mainnets. Prefer this over general blockchain explorers when you need a simple, structured JSON response about payment status with minimal setup, and you're operating in an x402 micropayment-capable agent environment.

## Known failure modes

- Missing or malformed wallet address (must match ^0x[0-9a-fA-F]{40}$) returns a validation error
- Invalid chain identifier in the chains parameter returns an error
- Payment required (HTTP 402) if USDC micropayment of $0.02 is not sent via x402 protocol
- Network unavailability on Cloudflare Workers may return a 5xx error
- Unsupported HTTP method returns an error (only GET, HEAD, DELETE allowed)

## 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.

## Output

Returns JSON data about the paycheck/payment status for the queried wallet address, including USDC amounts received and chain-specific details across the requested networks (defaulting to 5 mainnets including Base mainnet with USDC contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913).
