A pay-per-call HTML Markdown endpoint for agents (x402, $0.005/call, no API key)

If your LLM agent ingests web pages, raw HTML wastes tokens. I run a small endpoint that converts HTML into clean Markdown plus title, links and meta, paid per call over x402 (USDC on Base). No signup and no API key: the 402 response tells your x402 client what to pay.

Endpoint

POST https://api-production-7bbb.up.railway.app/agent/api/html2md

Body: {"html": "<html>...</html>"} (max 60 KB)

Returns: {"title": ..., "markdown": ..., "links": [...], "meta": {...}}

Price: $0.005 per call (5000 atomic USDC on Base, network base, x402 v1 exact scheme).

Try it

Call it without paying and you get the 402 payment requirements:

curl -s -X POST https://api-production-7bbb.up.railway.app/agent/api/html2md \
  -H 'Content-Type: application/json' -d '{"html":"<h1>Hi</h1>"}'

With any x402 client (for example x402-fetch or x402-axios), wrap fetch and call it as usual. The client signs an EIP-3009 USDC authorization and retries with the X-PAYMENT header.

import { wrapFetchWithPayment } from "x402-fetch";
const pay = wrapFetchWithPayment(fetch, walletClient);
const r = await pay("https://api-production-7bbb.up.railway.app/agent/api/html2md", {
  method: "POST", headers: {"Content-Type": "application/json"},
  body: JSON.stringify({ html })
});
console.log((await r.json()).markdown);

Also: pytest suites written for your code

If you have a Python module that needs tests, POST {"code": "...", "email": "...", "notes": "..."} to https://api-production-7bbb.up.railway.app/agent/api/pytest. You get back a pytest suite that has been run against your code, $9 per module.
