Overview

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.

FAQ from Trust Score X402

What is the x402 protocol and how do I pay?

x402 is an HTTP-native pay-per-call protocol that uses USDC on the Base L2 network (chain ID eip155:8453). When you make a request, the server responds with a 402 Payment Required challenge. Any x402-aware client handles the signing and retry cycle automatically. No API key or account setup is needed.

What checks does the server perform?

For a full scan, the server checks SSL certificate validity, DNS configuration, WHOIS data, security headers, and content analysis. You can optionally pass a subset of checks via the checks parameter (e.g., ["ssl","dns"]) for faster results under 2 seconds. A full scan takes 3–8 seconds.

How many targets can I evaluate at once?

The trust_score_batch_compare tool accepts 2–5 targets per request. The trust_score_evaluate tool processes a single target. For more than 5 targets, you would need to call the batch tool multiple times.

Are there any runtime dependencies or limits?

No—the server is zero-dependency. There are no rate limits or signup walls. Each API call costs a fixed micropayment: $0.01 for trust_score_evaluate and $0.02 for trust_score_batch_compare. The server is part of the klymax402 marketplace, which offers 100 similar x402 micropayment APIs.

What is this server not suitable for?

The trust score checks are not for SEO analysis, email validation, tech stack detection, or port scanning. For those tasks, the README suggests using other tools from the klymax402 ecosystem.
