How to use URL Metadata Extractor

  1. 1

    Paste the page HTML

    Paste a page's full HTML, from view-source or curl, or load the sample.

  2. 2

    Run the extractor

    It reads the <title>, meta description, canonical URL, Open Graph and Twitter tags, and every JSON-LD block.

  3. 3

    Check the warnings

    A missing <title> or missing Open Graph tags are flagged so you can fix them before the page is shared.

  4. 4

    Copy the JSON

    Copy the structured result into a ticket or SEO audit.

Questions and answers

Does it fetch the URL?
No. You paste the HTML; the extractor parses it in your browser and never requests the page.
What does it extract?
Title, meta description, canonical URL, Open Graph tags, Twitter card tags and parsed JSON-LD structured data.

Use it as an API

URL Metadata Extractor is also callable as a free HTTP JSON API at https://aidevhub.io/api/url-metadata-extractor/ — GET with query parameters or POST with a JSON body, no authentication, CORS enabled, fair use (abusive traffic is throttled at the edge; there is no per-request quota header). Responses return { ok, tool, result, meta }. 

curl -s -X POST https://aidevhub.io/api/url-metadata-extractor/ \
  -H "Content-Type: application/json" \
  -d '{"html":"<html><head><title>Example</title><meta property=\"og:title\" content=\"Example OG\"><link rel=\"canonical\" href=\"https://example.com\"></head><body>Hello</body></html>"}'
