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 'title' string with the page's <title> tag content, a 'metadata' object with key meta tags (e.g. description), and a 'links' array of objects each with 'href' and 'text' fields. Also includes an 'untrusted_content' boolean flag. No scripts are executed on the input HTML.
Example use cases
Link audit from crawled pages
“I've got the raw HTML from a competitor's product page — can you pull out every link in it along with the anchor text, so I can see where they're pointing?”
SEO metadata check
“Here's the HTML source of our homepage — can you extract the title tag and meta description so I can check if they're set correctly?”
Article preview card generation
“I fetched the HTML of this blog post and want to build a preview card — can you pull out the title, description, and any relevant links from this markup?”
Technical details
Endpoint
POSThttps://x402-agent.kariguetoazul.workers.dev/api/web/html-metadata?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you already have raw HTML in hand and need to extract structured metadata (title, description, links) without spinning up a full browser or executing JavaScript. It is ideal for lightweight, server-side HTML parsing tasks where you want fast, structured output at low cost ($0.002 USDC). Prefer this over full-browser scraping services when the content is static or pre-fetched, and over general LLM text extraction when you need deterministic structured fields like hrefs and meta tags.
Side effects
- HTML exceeding 12,000 characters will be rejected or truncated
- Malformed or non-HTML input may produce empty/partial results
- Dynamically rendered content (JavaScript-dependent) will not be captured since no script execution occurs
- Payment failure via x402 protocol will block access
- Missing or empty 'html' field returns an error
