Every endpoint supports three payment methods: crypto micropayments via [x402](https://www.x402.org/), card payments via [Stripe MPP](https://mpp.dev), and traditional API keys via [Stripe checkout](https://apimesh.xyz/signup).\n\n[**Live Site**](https://apimesh.xyz) -- [**Dashboard**](https://apimesh.xyz/dashboard) -- [**npm**](https://www.npmjs.com/package/@mbeato/apimesh-mcp-server) -- [**MCP Registry**](https://registry.modelcontextprotocol.io) -- [**Smithery**](https://smithery.ai/servers/apimesh/apimesh-mcp-server)\n\n---\n\n## Quick Start\n\n### Try free previews (no payment, no signup)\n\n```bash\ncurl https://core-web-vitals.apimesh.xyz/preview?url=https://example.com\ncurl https://security-headers.apimesh.xyz/preview?url=https://example.com\ncurl https://seo-audit.apimesh.xyz/preview?url=https://example.com\ncurl https://check.apimesh.xyz/preview?name=myapp\n```\n\n### Install the MCP server\n\nOne command to add all 67 tools to your AI coding assistant:\n\n```bash\nnpx @mbeato/apimesh-mcp-server\n```\n\nOr add to your MCP client config (`claude_desktop_config.json`, `.cursor/mcp.json`, etc.):\n\n```json\n{\n \"mcpServers\": {\n \"apimesh\": {\n \"command\": \"npx\",\n \"args\": [\"@mbeato/apimesh-mcp-server\"]\n }\n }\n}\n```\n\n### Direct API usage\n\n```bash\n# 1.

Every API has free `/health` and `/` info endpoints.\n\n---\n\n## The Autonomous Brain\n\nAPIMesh has an autonomous build loop that runs daily on the server. It discovers demand, generates APIs, tests them, and deploys to production — no human in the loop. It also maintains the [awesome-mpp](https://github.com/mbeato/awesome-mpp) ecosystem directory.\n\n```\nMonitor → Scanner → Scout → Build → Security Audit → Staging → Prod\n │ │ │ │ │ │\n │ │ │ │ │ └─ verify health\n �� │ │ │ └─ deploy + test endpoints\n │ │ │ └─ static analysis (secrets, SSRF, eval, etc.)\n │ │ └─ LLM generates multi-file Hono API (up to 6 retries)\n │ └─ gather market signals, score opportunities with LLM\n └─ check API health, revenue, error rates\n```\n\n**Hardened against prompt injection:** external signal data is sanitized, LLM prompts use system-role security rules, generated code is audited for 14+ vulnerability patterns, and the test environment is sandboxed with `.env` isolation.\n\nThe brain currently uses OpenAI (`gpt-4.1-mini`) for code generation and scores opportunities based on demand, implementation depth, and competitive differentiation.\n\n---\n\n## Tech Stack\n\n- [Bun](https://bun.sh) -- runtime and bundler\n- [Hono](https://hono.dev) -- web framework\n- [x402](https://www.x402.org/) + [MPP](https://mpp.dev) -- payment protocols\n- [Caddy](https://caddyserver.com) -- reverse proxy with automatic HTTPS\n- SQLite -- analytics and usage tracking\n- OpenAI -- autonomous API generation\n\n---\n\n## Related\n\n- [awesome-mpp](https://github.com/mbeato/awesome-mpp) -- the MPP ecosystem registry (100+ projects)\n\n---\n\n## Contributing\n\nContributions are welcome.
