AIPayGen Site Intel

Pay-per-call website and company intelligence for AI agents, served over MCP and a plain HTTP API, paid with prepaid credits or x402 USDC. Runs on Cloudflare Workers: no server to keep alive.

Use it

# Free key with trial credits
curl -X POST https://aipaygen.com/v1/keys

# HTTP
curl "https://aipaygen.com/v1/company_profile?domain=figma.com" -H "Authorization: Bearer apg_..."

# Claude Code
claude mcp add --transport http aipaygen https://mcp.aipaygen.com/mcp --header "Authorization: Bearer apg_..."

Without a key, paid endpoints answer 402 Payment Required with x402 v2 requirements (PAYMENT-REQUIRED header); x402 clients pay and retry with PAYMENT-SIGNATURE. Over MCP the payment goes in _meta["x402/payment"].

Develop

Requires Node.js 22+.

npm install
npm run db:migrate:local
npm run dev          # http://127.0.0.1:8787
npm test             # unit tests
npm run typecheck

Deploy

npx wrangler login
npx wrangler d1 create aipaygen          # paste the database_id into wrangler.jsonc
npm run db:migrate:remote
npx wrangler secret put ADMIN_TOKEN
npm run deploy

Then set in wrangler.jsonc → vars:

  • PUBLIC_URL: https://aipaygen.com
  • PAY_TO: your wallet address (enables x402)
  • X402_NETWORK: eip155:84532 (Base Sepolia testnet) or eip155:8453 (Base mainnet; needs a mainnet facilitator)

Uncomment the routes block to serve aipaygen.com, and add mcp.aipaygen.com / api.aipaygen.com custom domains so existing directory listings keep working.

Card top-ups: set STRIPE_SECRET_KEY and STRIPE_WEBHOOK_SECRET secrets and point a Stripe webhook (checkout.session.completed) at /billing/webhook.
