How this service works
Six payment-gated endpoints for AI agents: content extraction, price oracle, URL unfurling, web search, RSS parsing, and translation.
Output
Returns a structured object containing the URL's title, description, domain, siteName, image URL, favicon URL, canonicalUrl, twitterCard type, and Open Graph type — everything needed to render a rich link preview.
Example use cases
Example prompt
“Can you unfurl this link and tell me the title, description, and preview image from https://openai.com/research/gpt-4?”
Technical details
Endpoint
POSThttps://agentfeed.up.railway.app/api/v1/unfurlWhen to prefer
Choose this endpoint when you need rich link preview metadata (title, description, OG image, favicon, Twitter card) from a URL without scraping the full page body. Ideal for building link unfurlers, content cards, or enriching URLs in feeds. Prefer over full content extraction when you only need surface-level metadata rather than full article text.
Side effects
- URL is unreachable or returns non-200 status — metadata fields may be null or empty
- URL lacks Open Graph tags — title/description/image may fall back to inferred values or be null
- Payment not provided or insufficient — 402 Payment Required response
- Malformed URL input — validation error returned
- Dynamic/JS-rendered pages may not expose metadata to server-side fetch
