47620 Base + Polygon Data API — MCP server

Pay-per-call Base and Polygon onchain data for AI agents. No signup, no API key — every call is an x402 (HTTP 402) request settled in USDC, non-custodially. Pay on Solana, Base or Polygon — whichever your wallet supports.

Tools (18)

Per chain (base, polygon):

Use it (remote — no install)

Connect any MCP client to:

https://47620.xyz/mcp/evm

Streamable HTTP transport. Tool calls return the x402 challenge; an x402-capable runtime completes the USDC payment and retries. Works with Claude, Cursor, OpenClaw, Windsurf and any MCP-capable agent.

Use it (local, stdio)

npx -y 47620-evm-mcp

Claude Desktop / Cursor config:

{
  "mcpServers": {
    "47620-evm-data": {
      "command": "npx",
      "args": ["-y", "47620-evm-mcp"],
      "env": { "X402_PAY_URL": "https://your-pay-broker.example/pay" }
    }
  }
}

returns {header} — a base64 PAYMENT-SIGNATURE. Without it, tools return the 402 challenge and payment instructions.

  • X402PAYURL (optional): an HTTP pay broker that, given {url, challenge},

HTTP API

Facilitated mirrors under /x/base-fac/ and /x/polygon-fac/ are used by the remote MCP for marketplace discovery.

Payment

Every endpoint advertises accepts[] on all three chains:

  • Solana — USDC (SPL)
  • Base (eip155:8453) — USDC
  • Polygon (eip155:137) — USDC

1% platform fee is split at settlement; 99% goes to the merchant. Non-custodial.
