`startUrls`	array	Start pages. Internal pages are crawled (same host, robots.txt respected) and every link/image/script found is checked.
`urls`	array	Optional plain list of URLs to check status/redirects for, e.g. an old sitemap or backlink list.
`maxPages`	integer	Per run, across all start URLs.
`maxLinks`	integer	Cap on unique links checked.
`checkExternal`	boolean	Also check links to other domains (HEAD request, no crawl).
`onlyProblems`	boolean	Skip links that return 2xx with no redirect.
`maxConcurrency`	integer	Parallel checks. Each host is limited to ~4 requests/second.
`timeoutSecs`	integer	Per request.
