How It Works

x402 makes pay-per-call simple

The x402 protocol uses the HTTP 402 "Payment Required" response to handle micropayments natively. Your agent gets a payment challenge, pays in USDC on Base, retries the request, gets the data. No accounts, no API keys.

Agent calls endpoint

Standard GET request to /api/domain-shield?domain=example.com

Server returns 402

Payment challenge with price ($0.10–$0.15), wallet, and chain (Base).

Agent pays USDC

Agent settles on-chain via the x402 protocol and retries with payment header.

Data returned

Scored JSON with findings and recommendations. Sub-500ms response time.

# Example: 402 challenge response

Three ways to integrate

Use the MCP server, call endpoints directly, or discover via the x402 Bazaar.

Claude Desktop / Cursor

Add the Alderpost MCP server to your config and call endpoints as tools from any MCP-compatible client.

  "mcpServers": {
    "alderpost": {
      "command": "npx",
      "args": ["-y", "alderpost-mcp"]

Direct HTTP + x402

Any x402-compatible client can call endpoints. Get a 402, pay, retry. Use the x402-buyer-mcp for discovery.

# Discover and pay in one step
npx -y x402-buyer-mcp

# Or call directly
curl https://www.alderpost.co/api/
  domain-shield?domain=stripe.com
