Example prompt: What's the seller score for pay.sivut.co on the x402 network — can you look it up by domain and tell me the total score, rating, and what's driving it?

## When to prefer this

Use this endpoint when you need to assess the trustworthiness or reputation of an x402 seller before initiating a micropayment, or when building a directory or marketplace that surfaces x402 seller quality signals. It is the only known public scoring API specifically designed for the x402 protocol seller ecosystem.

## Known failure modes

- Missing required query parameter (domain, resource, or pay_to not provided) — likely 400 Bad Request
- Unknown domain or pay_to address with no scoring data — empty or null score response
- Network timeout or service unavailability — 5xx error
- Payment failure for the $0.03 USDC x402 fee — 402 Payment Required
