58 tools · x402 · USDC on Base

Agent tool marketplace

A directory of every deterministic utility an AI agent can call on FindUtils — grouped by what it does, priced per request from $0.0001. No account, no API key, no subscription. The agent reads the x402 manifest, picks a tool, signs one payment, gets the result.

Quickstart Pricing tiers

How an agent buys a tool

  1. 01
    Discover

    Fetch the x402 manifest to list every tool, its price, and its endpoint.

  2. 02
    Call

    Send the request. The first response is 402 Payment Required with the price.

  3. 03
    Pay

    Sign one EIP-712 USDC authorization for the exact amount — no wallet UI.

  4. 04
    Settle

    Replay the request; the facilitator verifies and the result returns inline.

Two ways to reach the catalog

REST

api.findutils.com — a plain HTTP endpoint per tool. Wrap your HTTP client with an x402 SDK and call it like any other API.

MCP

mcp.findutils.com — the same catalog as a Streamable HTTP MCP server. Drop it into Claude Desktop, OpenClaw, or any MCP-aware agent.
