Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/mini/web.page-meta--website-metadataWhen to prefer
Choose this endpoint when you need quick, lightweight extraction of page-level metadata (title, description, OG tags) from a URL without full browser rendering. It is ideal for link preview generation, SEO audits, or enriching records with website info. Prefer this over full-page scrapers when you only need head-level metadata and want fast, low-cost results at $0.002 per call.
Side effects
- URL is unreachable or returns a non-200 status — endpoint may return an error or empty metadata
- Page uses heavy JavaScript rendering — statically fetched metadata may be incomplete or missing
- URL is malformed or missing — input validation error returned
- Page blocks scrapers via robots.txt or rate limiting — metadata may be partial
- No meta tags present on page — response will contain minimal or empty fields
