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.

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: " \
  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 — 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 — no human in the loop. It also maintains the awesome-mpp ecosystem directory.

Monitor → Scanner → Scout → Build → Security Audit → Staging → Prod
  │         │        │          │              │        │
  │         │        │          │              │        └─ verify health
  ��         │        │          │              └─ deploy + test endpoints
  │         │        │          └─ static analysis (secrets, SSRF, eval, etc.)
  │         │        └─ LLM generates multi-file Hono API (up to 6 retries)
  │         └─ gather market signals, score opportunities with LLM
  └─ check API health, revenue, error rates

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.
