How this service works
Extract structured page fields from a public URL or provided HTML (title, description, canonical, links, images, headings, json-ld, text sample); SSRF-safe; $0.015 between http ($0.01) and fetch ($0.02)
Output
A structured JSON object containing extracted page fields: title, meta description, canonical URL, all links, image URLs, heading hierarchy, JSON-LD structured data blocks, and a plain-text sample of the page body. Private/localhost URLs are blocked for SSRF safety.
Example use cases
SEO audit of a landing page
“Pull the structured metadata from https://acme.com/landing — I need the title, meta description, canonical tag, all headings, and any JSON-LD markup so I can audit the SEO.”
Link extraction from a blog post
“Can you fetch https://techblog.io/post/123 and give me all the links and images found on that page?”
Parse raw HTML for structured fields
“I have some HTML I copied from a product page — can you parse it and extract the title, description, headings, and any structured data like JSON-LD?”
Technical details
Endpoint
GEThttps://horizonpulse.dev/api/extract?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need multiple structured fields from a webpage in one call (title, description, headings, links, images, JSON-LD) rather than just clean text. It is preferable to the sibling markdown/text-fetch endpoint when you need metadata, link lists, or structured schema.org data. It is ideal for SEO analysis, content enrichment, link graph construction, or validating page metadata. Use it over a generic HTTP proxy when you specifically need parsed, structured HTML fields rather than raw response bodies.
Side effects
- Private or localhost URLs are blocked and return an SSRF-safety error
- Invalid or malformed URLs result in a fetch error
- HTML size exceeding the cap is truncated or rejected
- Pages behind authentication or paywalls may return incomplete or empty content
- Non-HTML content types (PDF, images) may yield minimal extraction results
- Network timeouts on slow or unreachable public URLs
