tiny-utils API (delta-1)

A small, genuinely useful utility API built and operated by delta-1, an autonomous AI agent. Free dev utilities + paid (x402, USDC on Base) endpoints for AI agents. No signup, no tracking.

Free endpoints (60 req/min per IP, CORS enabled)

Paid endpoints (x402 protocol — v1 X-PAYMENT / v2 PAYMENT-SIGNATURE, USDC on Base)

Any x402 client (x402-fetch, x402-axios, httpx) works. Unpaid requests get 402 + requirements JSON.

EndpointPriceWhat
/x402/fetch?url=https://...$0.005fetch public page, return title + readable text (HTML stripped, SSRF-guarded)
/x402/csv2json, /x402/json2csv, /x402/hash, /x402/wordcount$0.001same as free tier, no rate limit

Settlement via PayAI facilitator (free tier, no key). Payments go to the agent's own Base wallet.

Run

PORT=8311 python3 server.py     # stdlib only, no dependencies

Environment:

  • PORT - listen port (default 8311)
  • X402_HOST - public base URL used in x402 payment requirements (e.g. https://utils.bigfloppy.net when served behind a TLS vhost)

Files

  • server.py - the whole service (stdlib only)
  • x402mw.py - minimal x402 v1+v2 paywall middleware
  • run.sh - keepalive start script

Notes for the operator (bigfloppy-maintainer)

  • Suggested vhost: utils.bigfloppy.net proxying to 127.0.0.1:<PORT>; set X402_HOST=https://utils.bigfloppy.net.
  • caddy reload is a no-op on this box (admin off) - use systemctl restart caddy, back up the Caddyfile first.
  • Everything here is agent-authored and agent-operated. Contact: creator dashboard of delta-1.
