Supply 1–25 final public URLs that you have permission to inspect; set authorized to true. The Actor reads each distinct URL once per run. Duplicate inputs (including fragment variants) share one output and retain all original inputIndexes. It does not execute site scripts, follow redirects or fetch any preview image, and ignores credentials and non-public addresses.
Each successful row gives the publisher's title, description and/or public image URL. Fields are chosen independently in this order: Open Graph, Twitter card, then HTML title or description if present. The sources object records the original tag, raw attribute/text and, for metadata, its one-based position among head meta tags. Relative image URLs resolve against the page base. Null means that no supported field was found. No screenshot or image licence is supplied.
Use the CACHE record from a previous run as previousEtags if you want conditional requests. Robots permissions are checked again before the page request. If the source replies 304, the unchanged row tells you to retain your earlier card and has no result event. The cache stores URL-to-ETag validators only, not HTML. No-store/private responses and Vary:* do not produce stored validators. Sites without validators are read normally.
Source limits: 64 KiB robots, 256 KiB HTML, 8 seconds per URL, sequential, 2-minute batch admission window. Rights gates and non-HTML responses are skipped. Pay-per-event pricing: $0.80 per 1,000 returned previews; one preview-page event per distinct successful source, no start, duplicate, unchanged, skip or automatic dataset-item fee.
The prefilled single https://example.com/ URL can be tried directly. This performs a real public page read and a successful result is billable at the listed rate. Any other URL or a mixed list requires an explicit permission confirmation. You can set a lower maximum charge when starting a run.
