Documentation Overview
APIMesh
Pay-per-call web analysis APIs for AI agents and developers. Security audits, performance monitoring, SEO analysis, email verification, tech stack detection, and more -- no signup required, just pay with USDC on Base and get your response.
APIMesh is a collection of 102 focused web analysis APIs, each on its own subdomain, with a 67-tool MCP server for direct use in Claude, Cursor, Windsurf, Cline, and any MCP-compatible client. Every endpoint supports three payment methods: crypto micropayments via x402, card payments via Stripe MPP, and traditional API keys via Stripe checkout.
