How this service works
Extract webpage metadata from one public URL: page title, meta description, canonical URL, headings, hreflang, icons, feeds, Open Graph, Twitter Cards, and JSON-LD Schema.org types, with redirect and response provenance plus privacy-safe, publisher-asserted Organization facts with field evidence.
Output
A structured JSON object containing canonical URL, page title, meta description, Open Graph properties (og:title, og:description, og:image, og:type, etc.), Twitter Card tags, author information, publication date, and other standard document metadata extracted from the target web page.
Example use cases
Social preview before sharing link
“Before I post this link on social media, can you pull the Open Graph title, description, and image metadata from https://techcrunch.com/2024/05/01/ai-agent-trends/ so I know how it'll look when shared?”
SEO canonical URL audit
“I need to check the canonical URL and meta description for https://www.mysite.com/blog/best-practices — can you extract all the page metadata so I can audit it for SEO?”
Article metadata enrichment pipeline
“I'm building a reading list and need the title, author, publication date, and canonical URL extracted from https://www.wired.com/story/the-future-of-work — can you grab all that structured metadata for me?”
Technical details
Endpoint
POSThttps://apiacre.com/v1/web/metadataWhen to prefer
Choose this endpoint when you need structured, normalized metadata (canonical URL, Open Graph, Twitter Card, document meta) from a web page without building your own HTML parser. It is ideal for link-preview generation, SEO audits, content enrichment pipelines, and reading list apps. Prefer this over generic web scraping when you specifically need social and canonical metadata rather than full page content.
Side effects
- URL is unreachable or returns a non-200 status — error indicating fetch failure
- Page uses heavy JavaScript rendering with no static metadata — incomplete or empty metadata fields returned
- Target site blocks bots or scrapers — access denied or empty response
- Malformed or non-HTML URL (e.g. PDF, image) — limited or no metadata extracted
- Missing Open Graph tags — only canonical and basic HTML meta returned
