Preflight trust check of another x402 endpoint before an agent pays it.

Preflight trust check of another x402 endpoint before an agent pays it. From the target resource URL: a composite trust score 0-100, a category (trusted / caution / untrusted / unknown), per-dimension flags, reasons and weighted signals. Scored from CDP x402 Bazaar discovery, an on-chain USDC payment-diversity sample, and a live 402 probe that the served payTo matches the listing. Trust indicators, not a guarantee.
