What is Trust Score X402?
Trust Score X402 is an MCP server that evaluates the trustworthiness of any domain, URL, wallet address, or API endpoint. It returns a composite score from 0 to 100 with five sub-scores (SSL, DNS, WHOIS, security headers, and content), a letter grade (A+ to F), and a verdict (trusted/moderate/suspicious/dangerous). It is designed for AI agents that need to check safety before interacting with unknown services, and it is pay-per-call via the x402 protocol using USDC on Base L2.
How to use Trust Score X402?
Add the server to your MCP client configuration (Claude Desktop, Cursor, ElizaOS, etc.) with the URL https://trust-score.api.klymax402.com/mcp. Alternatively, call the HTTP endpoint directly with an x402-aware client (e.g., @x402/fetch). Each call triggers a 402 Payment Required challenge that the client resolves automatically by signing a USDC micropayment. No signup, API key, or rate-limit walls are required.
