## 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-risk-score-base-mainnet-address-endpoint-risk-analysis-4bd2e309
```

Example prompt: Can you check the risk score for wallet address 0x1234567890abcdef1234567890abcdef12345678 on Base mainnet? I want to know if it's safe to send USDC to before I proceed.

## When to prefer this

Use this endpoint when you need a quick on-chain risk score specifically for Base mainnet wallet addresses or x402 payment endpoints using USDC, particularly before initiating a payment or integration. Prefer this over general blockchain analytics tools when you are already operating within the x402 payment ecosystem and want a lightweight, per-call risk check that itself costs $0.01 USDC via x402.

## Known failure modes

- Invalid address format (not a valid 0x hex address) returns validation error
- Address not found or no on-chain history may return low-confidence or null score
- Payment not made or x402 payment rejected results in 402 response before data is returned
- Unsupported network value returns error (only 'base' and 'base-sepolia' are valid)
- Endpoint URL not publicly reachable returns error
- Timeout if Base RPC is congested

## 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

A JSON response containing a risk score and associated signals for the queried Base mainnet wallet address or x402 endpoint, reflecting on-chain USDC activity and behavioral patterns that indicate trustworthiness or suspicious activity.
