Lists the Broken Links Checker runs of every website the token can reach, as a JSON:API collection of type site-broken-link-scans with the usual links / meta pagination.
Each entry carries status (pending, done, failed, failed_partial), type (full - every published content type; page - only the pages named at launch), method (manual, automatic, force_first), site_id, the crawl counters (parts_total, parts_done, parts_failed, parts_empty, pages_enumerated, links_enumerated, pages_planned, links_planned, total_batches, current_batch - 0 until the plugin reports), error_code / error_message (null unless the run failed), created_at, updated_at and finished_at (null while still running).
A scan takes from minutes to several hours: a launch never waits for it to finish - poll this listing and read status. The findings themselves are not here: they are “Broken Links Issues” › “List Broken Links issues” and “Broken Links Pages” › “List Broken Links pages”.
Websites of other organizations - and members without the read permission - answer 404; an unknown filter answers 400 and an invalid value 422. A read-only token is enough. The MCP twin of this endpoint is the site-broken-link-scans-index tool.
