A pay-per-call utility API for AI agents.
100+ deterministic tools — encode, hash, format, parse, generate — settled per request in USDC over the x402 protocol. No keys, no plans, no rate-limit negotiations.
Three lines, one settled call
import { wrapAxiosWithPayment } from '@x402/axios';
import axios from 'axios';
const api = wrapAxiosWithPayment(axios.create(), signer);
// Just call. The library handles the 402 challenge transparently.
const { data } = await api.post(
'https://api.findutils.com/api/tools/json-format/execute',
{ input: '{"a":1,"b":2}' }
);
First call: 402 Payment Required. The agent SDK signs an EIP-712 authorization for $0.0002, replays the request, and you get the result. Total roundtrip ≈ 600ms.
Built for agent traffic
Pay per call
No subscription, no API key dance. Sign one EIP-712 authorization per request, settle in USDC on Base, get your result. Prices range from $0.0001 to $0.005 per tool.
100+ deterministic tools
Hashes, encoders, JSON / CSV / YAML / XML, slug + UUID generators, regex match, cron explain, JWT decode, CIDR calc, URL meta fetch — anything an agent might need to clean or parse data mid-flow.
No infrastructure to run
Hosted on Cloudflare's global edge, ~10ms cold response time, fail-closed on payment, atomic verify-then-settle through our own facilitator (no third-party trust chain).
MCP-native
mcp.findutils.com exposes the same catalog as a Streamable HTTP MCP server. Drop it into Claude Desktop, OpenClaw, or any MCP-aware agent.
