The API returns metadata extraction results, page title, meta description, canonical URL, Open Graph tag values, social card tag values, duplicate tags, empty tags, metadata found status, validation status, errors, warnings, recommendations, normalized social preview output, image URL validation output, and technical disclaimer.
This API is useful for SEO teams, developers, SaaS builders, CMS platforms, marketing agencies, technical SEO consultants, content platforms, frontend teams, backend teams, QA teams, ecommerce platforms, publisher sites, news sites, blog platforms, product teams, web audit platforms, site monitoring services, SEO software companies, internal tooling teams, social media teams, content QA teams, landing page builders, no-code website builders, developer platforms, and marketing automation platforms.
The API checks metadata submitted by URL or raw HTML and returns technical extraction and validation results. It does not hack, brute force, attempt logins, scan private systems, scrape restricted content, bypass robots.txt, change customer data, send emails, create calendar events, guarantee ranking outcomes, guarantee social preview rendering, guarantee click-through rate, guarantee platform approval, guarantee preview cache updates, or replace professional SEO review.
The API response includes a data_disclaimer field explaining that the validation is based only on metadata submitted by URL or raw HTML and is provided for technical review purposes. Results should be reviewed before use in SEO, publishing, social media, marketing, compliance, operational, or business decisions.
Each endpoint returns metadata extraction and validation results, including page title, meta description, canonical URL, Open Graph tag values, social preview tag values, duplicate and empty tags, errors, warnings, recommendations, and validation status.
Key fields include "ok" (status), "metadataFound" (indicating presence of metadata), "errors" (list of issues), "warnings" (suggestions for improvement), and "recommendations" (best practices for metadata).
The response data is structured in JSON format, with a top-level "ok" field indicating success, followed by nested objects for metadata details, errors, warnings, and recommendations, making it easy to parse and utilize.
Each endpoint provides information on metadata extraction, validation results, social preview construction, and image URL checks, covering aspects like title, description, images, and validation status.
Users can customize requests by submitting specific URLs or raw HTML content to the endpoints. The response is based on the submitted webpage or HTML structure and the metadata fields found during extraction and validation.
"valid" indicates whether the metadata passed the endpoint checks, "titleLength" and "descriptionLength" provide character counts, while "duplicateTags" and "emptyTags" list metadata issues found in the submitted content.
Typical use cases include checking social preview metadata, reviewing missing or empty preview fields, validating preview image URLs, finding duplicate metadata tags, and identifying technical warnings or errors in submitted webpage or HTML content.
Data reflects technical metadata extraction and validation checks on the submitted webpage or raw HTML at the time of the request. Results may vary based on page content, redirects, metadata format, image URLs, and parsing behavior.
