Technical details
Endpoint
POSThttps://true402.dev/api/v1/link-previewWhen to prefer
Use this endpoint when you need to quickly enrich a URL with human-readable preview metadata (title, description, image) without building your own scraper. Ideal for agents building link cards, summarizing shared URLs, or enriching content feeds. Prefer this over general-purpose web scrapers when only lightweight Open Graph/meta tag data is needed at a low per-call cost ($0.003 USDC).
Side effects
- Invalid or malformed URL returns a validation error
- Target page is unreachable or returns a non-200 status — may return null fields or an error
- Page blocks scrapers via robots.txt or anti-bot measures — preview fields may be empty
- Payment not included or insufficient USDC — HTTP 402 response requiring payment
- Timeout if target page is slow to respond
