Cursor

Important: Cursor has a 60s timeout. Pre-install globally first: npm install -g @serendb/x402-mcp-server

First, install globally to avoid timeout issues:

npm install -g @serendb/x402-mcp-server

Then add to ~/.cursor/mcp.json:

{
  "mcpServers": {
    "x402": {
      "command": "x402-mcp-server",
      "args": [],
      "env": {
        "X402_GATEWAY_URL": "https://x402.serendb.com",
        "WALLET_PRIVATE_KEY": "0x...",
        "BASE_RPC_URL": "https://mainnet.base.org",
        "SERENDB_CONNECTION_STRING": "postgresql://..."
      }
    }
  }
}

Also works with Windsurf, Zed, and other MCP-compatible clients. See the full setup guide for details.

For Developers

Direct HTTP API

Access data directly via HTTP using the x402 payment protocol.

How x402 Payments Work
  1. Send your query request to the gateway
  2. Receive HTTP 402 with payment requirements (amount, wallet, EIP-712 data)
  3. Sign the payment authorization with your wallet
  4. Retry request with X-PAYMENT header containing the signature
  5. Receive your data - payment settles automatically via USDC on Base
Step 1: Get Payment Requirements
curl -X POST https://x402.serendb.com/api/proxy \
  -H "Content-Type: application/json" \
  -d '{
    "publisherId": "2723d9ce-2b4e-4654-91d1-eceb10043ac7",
    "agentWallet": "0xYourWalletAddress",
    "request": {
      "method": "GET",
      "path": "/endpoint"
    }
  }'

This returns 402 Payment Required with the payment details you need to sign.

Step 2: Add Payment Header

After signing the EIP-712 authorization, add the base64-encoded signature:

curl -X POST https://x402.serendb.com/api/proxy \
  -H "Content-Type: application/json" \
  -H "X-PAYMENT: <base64-encoded-signature>" \
  -d '{ ... }'
