Agent Data API — MCP Server

MCP server exposing 18 pay-per-call data tools + 1 free tool for AI agents: crypto & DeFi market data (cross-exchange funding rates, market-regime signal, TVL, yields, stablecoin pegs), web extraction (clean text, Markdown, metadata), PDF-to-text, RSS/Atom parsing, FX rates, crypto prices, weather, DNS and email validation.

Payments use the x402 protocol — USDC on Base, per-call, no API keys, no accounts, no subscriptions.

Quick start (Claude Desktop / Cursor / any MCP client)

{
  "mcpServers": {
    "agent-data-api": {
      "command": "npx",
      "args": ["-y", "agent-data-api-mcp"]
    }
  }
}

Then ask your agent to try the free tool:

"Use crypto_fear_greed to check crypto market sentiment."

How payment works

The free tool returns data immediately. Paid tools call the API; if payment is required, the tool returns the machine-readable x402 payment requirements (price, network eip155:8453, asset USDC, pay-to address) so an x402-capable client or wallet-equipped agent can settle and retry. This MCP server holds no keys and signs nothing.
