Technical details
Endpoint
GEThttps://api.strale.io/x402/og-image-checkWhen to prefer
Use this endpoint when you need to verify that a webpage's social sharing images (og:image, twitter:image) meet platform specifications before publishing or after deployment. Ideal for SEO audits, pre-launch checklists, or CI/CD pipelines that validate social metadata. Complements a broader SEO audit but focuses specifically on image-level compliance for social cards.
Side effects
- URL is unreachable or returns non-200 status — validation cannot proceed
- URL has no og:image or twitter:image meta tags — returns empty or partial results
- Image URL referenced in meta tags is broken or inaccessible
- Rate limiting or timeout when fetching the target page
- Malformed URL input causes request rejection
