Skill: Any URL to markdown

Bundled execution of the Any URL to markdown workflow — The 'I have a URL but it might be HTML, PDF, or an image — give me clean markdown either way' workflow. HEAD-detect the content-type, branch to the right deterministic extractor (article extract for HTML, pdf-to-markdown for PDFs, OCR for images), and report token/word stats on the output so the caller can budget the result against an LLM context window. One x402 payment runs 6 underlying tools (http-headers, extract, pdf-to-markdown, image-ocr, html-to-markdown, text-stats); partial-success per step.

Input

Field	Type	Description
url *	string	Public http(s) URL to convert to markdown. Can point at an HTML article, a PDF, or an image — the workflow auto-detects.

Try it — see the 402 challenge (free)

curl -i -X POST https://agent402.tools/api/skill/any-to-markdown \
  -H "Content-Type: application/json" \
  -d '{"url":"https://example.com"}'

The response is HTTP 402 Payment Required with exact payment requirements. Any x402 v2 client pays automatically and retries:

Paid call (JavaScript agent)

import { wrapFetchWithPayment } from "@x402/fetch";
import { x402Client } from "@x402/core/client";
import { registerExactEvmScheme } from "@x402/evm/exact/client";
import { privateKeyToAccount } from "viem/accounts";

const client = new x402Client();
registerExactEvmScheme(client, { signer: privateKeyToAccount(KEY) });
const payFetch = wrapFetchWithPayment(fetch, client);

const res = await payFetch("https://agent402.tools/api/skill/any-to-markdown", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    "url": "https://example.com"
  }),
});

Wallet-only. This tool reaches the network/browser/storage, so it is paid in USDC via x402 (no proof-of-work tier).
