Questions

ox402-utils

94 capability APIs an AI agent can't run in its own sandbox — paid per call via x402 (USDC on Base). Web research, security recon, neural text-to-speech (Kokoro-82M), speech, document + media conversion, full-page screenshots, SSL/breach audits, SQL sandboxes, embeddings, and more. No accounts, no API keys, no subscription. Free trial: 10 calls/IP on tier=free tools.

Live site: the current tunnel URL is published in api.txt and /.well-known/x402 on this repo's served docs, and rotates periodically — fetch api.txt for the live endpoint. MCP server: /mcp402/ · Catalog: /x402/catalog · Machine-readable: /llms.txt

Why this exists

An AI agent's sandbox can't open a browser, run a GPU TTS model, scan a host for open ports, or audit a site's TLS. ox402 does those for it — and bills per call in USDC. No signup, no API key, no monthly minimum. Every call is authorized by an on-chain micropayment (x402): hit the endpoint, get a 402 challenge, pay the exact amount, retry with the X-Payment header.

Free trial: 10 calls/IP on tier=free tools. Paid-tier tools always require x402 USDC.

Use it in 30 seconds (curl)

# Free trial (10 calls/IP): no payment needed
curl -X POST http://129.213.128.185/x402/trial/search \
  -H 'Content-Type: application/json' \
  -d '{"query":"x402 protocol","count":3}'

# Paid tier: POST -> 402 challenge -> pay -> retry with X-Payment header
curl -i http://129.213.128.185/x402/paid/search \
  -H 'Content-Type: application/json' \
  -d '{"query":"x402 protocol","count":3}'

The 402 response carries a PAYMENT-REQUIRED challenge with the exact USDC amount and the payTo address. Pay on Base, then repeat the request with the signed payment in the X-Payment header (any x402 client: the Coinbase x402 fetch wrapper, or your own signer). Verified + settled via our self-hosted facilitator (melonask/facilitator) on Base mainnet.

tools/list is free and returns all 94 tools (compact ~1.6k-token menu; full schemas on demand). tools/call returns the payment instructions when unpaid. Drop it into Claude Desktop, Cursor, or any MCP framework and the agent can pay-to-use every tool.
