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.

Quick Start
Try free previews (no payment, no signup)
curl https://core-web-vitals.apimesh.xyz/preview?url=https://example.com
curl https://security-headers.apimesh.xyz/preview?url=https://example.com
curl https://seo-audit.apimesh.xyz/preview?url=https://example.com
curl https://check.apimesh.xyz/preview?name=myapp
Install the MCP server
One command to add all 67 tools to your AI coding assistant:
npx @mbeato/apimesh-mcp-server
Or add to your MCP client config (claude_desktop_config.json, .cursor/mcp.json, etc.):
{
"mcpServers": {
"apimesh": {
"command": "npx",
"args": ["@mbeato/apimesh-mcp-server"]
}
}
}
Direct API usage
# 1. Hit any paid endpoint -- returns 402 with payment details
curl https://core-web-vitals.apimesh.xyz/check?url=https://example.com
# 2. Include x402 payment header -- returns the full response
curl -H "X-PAYMENT: <signed-usdc-payment>" \
https://core-web-vitals.apimesh.xyz/check?url=https://example.com
All APIs
Every API lives on its own subdomain: https://{api-name}.apimesh.xyz
Web Analysis APIs
Developer Utility APIs
Autonomously Built APIs
These APIs were built, tested, and deployed by APIMesh's autonomous brain loop โ no human wrote the code:
New APIs are added automatically as the brain discovers demand and builds solutions. See How the Brain Works below.
Wallet & Spend Tracking (free, no auth)
Payment Methods
APIMesh supports three ways to pay:
1. x402 -- crypto micropayments (default)
Agent request --> 402 Payment Required (price, wallet, network)
Agent signs USDC on Base --> includes X-PAYMENT header
Server verifies via Coinbase CDP --> returns response
No accounts. No API keys. No subscriptions. The agent handles payment autonomously.
- Protocol: x402 (open standard)
- Currency: USDC on Base (chain ID 8453)
- Facilitator: Coinbase CDP
2. MPP -- Stripe Machine Payments Protocol
Stripe MPP enables AI agents to pay with cards or stablecoins through Stripe's infrastructure.
3. API key + credits
Traditional auth for developers who prefer it. Purchase credits via Stripe checkout and include your API key in requests.
Discovery & Integration
Most APIs offer free /preview endpoints so agents can verify functionality before paying. Every API has free /health and / info endpoints.
The Autonomous Brain
APIMesh has an autonomous build loop that runs daily on the server. It discovers demand, generates APIs, tests them, and deploys to production โ no human in the loop. It also maintains the awesome-mpp ecosystem directory.

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.
The brain currently uses OpenAI (gpt-4.1-mini) for code generation and scores opportunities based on demand, implementation depth, and competitive differentiation.
