## 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

```

Example prompt: Can you check whether this Ethereum address 0x742d35Cc6634C0532925a3b844Bc454e4438f44e is safe to interact with — I want to know its trust score, any scam or mixing associations, and overall risk level before I send funds.

## When to prefer this

Choose this endpoint when you need to assess the trustworthiness and risk profile of a specific blockchain wallet or payment address before initiating a transaction, especially when fraud detection, scam association checks, or mixing pattern analysis are required. It is particularly suited for x402-enabled agentic payment flows where automated due diligence on counterparty addresses is needed at low cost ($0.01 USDC per call).

## Known failure modes

- Invalid or malformed blockchain address returns a validation error
- Unsupported blockchain network returns an unsupported network error
- Address with no transaction history may return limited scoring data
- Payment failure (insufficient USDC) results in 402 Payment Required
- Service downtime returns 503 or health-check failure
- Rate limiting may return 429 Too Many Requests
