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.

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

Autonomously Built APIs

These APIs were built, tested, and deployed by APIMesh's autonomous brain loop — no human wrote the code:

Domain Intelligence Aggregator	GET /check?domain=	$0.005	WHOIS, DNS records, SSL certificates, and historical analysis in a single report

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.

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.
