x402 MicropaymentsUSDC on BaseMCP ServerOpenAPI 3.1

Quick Start

Three ways to use PROWL: direct HTTP with x402 payments, the x402 fetch wrapper, or as an MCP tool server for AI agents.

1. Try a free endpoint

curl https://prowldata.dev/api/v1/crypto/health

2. Pay for data with x402 (Node.js)

Install the x402 client, then call any paid endpoint. Payment happens automatically.

npm install x402

import { paymentFetch } from "x402/client";

// Your wallet private key (USDC on Base)
const PRIVATE_KEY = "0x...";

const res = await paymentFetch(
  "https://prowldata.dev/api/v1/markets/odds?category=politics",
  {},
  { privateKey: PRIVATE_KEY }
);
const data = await res.json();
console.log(data);
// Cost: $0.001 per call, settled instantly on Base

3. Connect via MCP (AI agents)

Add PROWL as a tool server in Claude, Cursor, or any MCP-compatible agent.

# Claude Code
claude mcp add prowl --transport http https://prowldata.dev/mcp

# Or add to your MCP config:
{
  "mcpServers": {
    "prowl": {
      "url": "https://prowldata.dev/mcp"
    }
  }
}
