Example prompt: I've got the raw HTML for a webpage — can you extract its title and all the common meta tags like description, keywords, and Open Graph fields from it and give me the results as structured JSON?

## When to prefer this

Choose this endpoint when you already hold raw HTML locally and need a lightweight, stateless, deterministic extraction of page title and standard meta tags without firing a live web request or using a browser. It is ideal for agent preflight steps, link preview generation, and SEO audit pipelines where you want structured metadata at minimal cost ($0.002 USDC) and without retaining any input data upstream.

## Known failure modes

- Malformed or empty HTML input returns partial or empty results
- Missing meta tags in the HTML result in absent fields in the output JSON
- Very large HTML strings may hit request size limits
- HTML with non-standard or custom meta tag formats may not be fully captured
- Network or payment authorization errors prevent execution

## How this service works

Extract title and common meta tags from caller-held HTML — first-party local utility for agent preflight and proven micro-utils expansion. Returns deterministic machine-readable JSON for $0.002 USDC via x402 on Base.

Results are advisory; the caller owns authorization, budgets, and production controls. Sibling of Delx routes that already conver…

## Output

A deterministic machine-readable JSON object containing the page title extracted from the <title> tag and key meta tag values found in the HTML (e.g. description, keywords, Open Graph tags like og:title, og:description, og:image). The response is stateless and advisory — no data is retained server-side.
