Agent-native utility API bundle. 9 endpoints exposed as both REST API and MCP server (streamable-http), with x402 micropayments. Live at tools.beethoven2024.com.
For AI agents (Claude, Cursor, custom): Add this MCP server to your config and use 9 utility tools instantly.
For developers: Standard REST API. Use any subdomain example below as a working sample.

Free: /health, /, /docs (OpenAPI), and MCP protocol methods initialize / tools/list / ping. All 9 tools require x402 payment via both MCP (tools/call) and REST (/v1/*).
Every endpoint solves a problem agents can't easily do locally:
8 of 9 endpoints are fully self-hosted (zero upstream API cost). Only IP geolocation uses an external free-tier API.
Every paid endpoint returns HTTP 402 Payment Required with the price spec when no payment is included. x402-capable agents handle this automatically:
transferWithAuthorization for USDC on BaseX-PAYMENT headerSettlement happens on-chain on Base. Sub-2-second confirmation.
Runs on Base mainnet by default. Set AGENT_TOOLS_TESTNET=true to use Base Sepolia with the public testnet facilitator.
Coming soon: API key + Stripe usage billing for human developers and businesses.

AGENT_TOOLS_PAY_TO | No | (empty) | EVM wallet address for receiving USDC payments. Leave empty to run free/dev mode. |
