How this service works
HTML to Markdown: Same Page, Nothing Invented — Converts HTML into CommonMark Markdown and answers with the Markdown only, no wrapper fence. Headings become ATX headings, links keep their address byte for byte (title included), images keep their source and alt text, lists keep nesting and an ordered list keeps the number it begins with, code blocks keep their text and indentation, tables become pipe tables with literal pipes escaped, entities are decoded once so the text reads as a browser show…
Output
Returns a JSON object containing: the SKILL.md file name and UTF-8 text content (instructions for HTML-to-Markdown conversion), the skill identifier ('html-to-markdown'), a SHA256 hash of the file for integrity verification, the version string (e.g. '1.0.0'), a payment receipt with the Base blockchain settlement transaction hash and settled status, and a redownload URL and token for future free re-downloads.
Example use cases
Equip agent with HTML conversion skill
“Get me the HTML to Markdown skill file from AISkills402 so my agent knows exactly how to convert web pages to clean Markdown without inventing anything — pay the $0.01 USDC fee and save the redownload token.”
Audit skill file integrity
“Download the html-to-markdown SKILL.md from AISkills402 and give me the SHA256 hash so I can verify the file matches what I already have cached.”
Onboard new agent with conversion capability
“My new agent needs to convert HTML documents to Markdown — buy the html-to-markdown SKILL.md from AISkills402 and hand me back the file content and the version number so I can log it.”
Technical details
Endpoint
GEThttps://api.aiskills402.com/v1/skills/html-to-markdown/file?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs a tested, standardized SKILL.md instruction file specifically for HTML-to-Markdown conversion, and you want a one-time purchase model with permanent ownership and free redownloads. Prefer this over building a custom prompt when you want a community-tested, versioned skill definition that an agent can follow reliably. Best suited for agents operating on Base with USDC via the x402 micropayment protocol.

- Network or API downtime — service unavailable, returns 503
- Malformed request headers — missing or invalid header format returns 400
