How this service works
Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.
Output
Returns a JSON object containing a 'markdown' field with the converted Markdown string, plus an 'untrusted_content' flag set to true indicating the output originates from caller-supplied HTML and should be treated as untrusted content downstream.
Example use cases
Clean scraped article for LLM ingestion
“I've got the raw HTML of a news article I scraped — can you convert it into Markdown so I can feed it into my summarization pipeline? Here's the HTML: '<article><h2>Breaking News</h2><p>Markets rose <em>sharply</em> today.</p></article>'”
Render email template as readable notes
“Take this HTML email template I have and turn it into plain Markdown so I can read the content without all the tags. Here it is: '<div><h1>Welcome</h1><p>Thanks for signing up! <a href="#">Click here</a> to get started.</p></div>'”
Convert CMS output for static site docs
“My CMS is spitting out HTML and I need it as Markdown for my docs site — can you transform this block for me? '<section><h3>Getting Started</h3><ol><li>Install the package</li><li>Run the server</li></ol></section>'”
Technical details
Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/web/html-markdown?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have a raw HTML string (up to 12,000 characters) that needs to be converted to Markdown server-side without script execution risk. Useful in agent pipelines that scrape web content and need clean Markdown for downstream LLM processing, documentation generation, or readable storage. Prefer this over client-side HTML parsers when you need a sandboxed, pay-per-call microservice with no infrastructure overhead.
Side effects
- HTML string exceeds 12,000 character limit — request rejected
- Malformed or missing 'html' field in request body — validation error
- Payment not provided or insufficient (x402 payment required, $0.002 USDC) — 402 response
- Server-side worker timeout or execution quota exceeded — 5xx error
