Link & Social Card Preview

Inspect a public link

The server fetches static HTML metadata of a public http(s) page under a strict SSRF policy and returns the status, final URL and social-card fields; missing fields are listed explicitly.

Inputs and parameters

• url — Public URL

Real example

POST /api/v1/inspect  {"url":"https://example.com/article?utm=private#frag"}
(head contains <title>Sample article</title>, <meta name="description" content="A description">, <link rel="canonical" href="/article">, <meta property="og:title" content="Sample article">, <meta property="og:image" content="/img/card.png">, <meta name="twitter:card" content="summary_large_image">)
→ HTTP 200 {"data":{"requestedUrl":"https://example.com/article","finalUrl":"https://example.com/article","status":200,"title":"Sample article","description":"A description","canonical":"https://example.com/article","openGraph":{"title":"Sample article","image":"https://example.com/img/card.png"},"twitter":{"card":"summary_large_image"},"warnings":["All fields were found","Static HTML metadata: no JS, no screenshots, no promise of matching platform caches","OG image not loaded automatically"],"checkedAt":"2026-11-15T00:00:00.000Z"},"requestId":"…"}
Note: the utm=private query and fragment appear in neither result nor logs; relative canonical / og:image are resolved to absolute URLs; og:image shows only a URL + placeholder.

Limits and failure handling

Defaults: 10 s total budget, separate connect timeout, 2 MiB decompressed HTML, max 3 redirects, process concurrency 4, bounded 10-minute cache. HTML only; timeouts, oversized/compressed responses, non-HTML content and invalid certificates yield readable errors. First release: no target JS execution, no screenshots, no promise of matching platform caches, no shared query history. OG image preview requires a click and a backend-restricted fetch under the same policy.
