Trust Score API
Evaluate trustworthiness of any domain, URL, wallet, or API. Returns 0-100 score with 5 sub-scores: SSL, DNS, WHOIS, security headers, content. Zero-cost, zero-dependency. The trust layer agents need before interacting with unknown services. Pay-per-call via x402 (USDC on Base L2) -- no API key, no signup, no rate-limit wall.
