schemaVersion
Optional
Row contract version ("1").
domain
Optional
Normalized domain (lowercase, no scheme, path or www.). null for invalid input.
inputValue
Optional
The value as given in the input.
resolvedHost
Optional
Host the homepage redirected to (without www.). null when the homepage could not be reached.
crossDomainRedirect
Optional
true when the homepage redirects to a different registrable domain. Results, status and billing then refer ONLY to the domain you entered: links and names from the destination website are not used, Meta needs ads that link to the entered domain and LinkedIn is not checked (reason cross_domain_redirect). The destination is reported separately in redirectTarget. null for rows that were not checked.
redirectTarget
Optional
Information only — never changes status, isRunningAds, platformsWithAds, totalAdsCount or billing. Present when the homepage redirects to a different registrable domain: domain (the destination host), checkedPlatforms (["google"] or [] when Google was not selected) and google (the Google result for ads pointing to the destination domain, same shape as the google field). The destination can belong to another company (acquisition, expired domain bought by someone else), so its ads are not presented as ads of the entered domain. Meta and LinkedIn are not checked for the destination. null when there is no cross-domain redirect.
status
Optional
ok = every selected platform was resolved (active or not_found) — the only charged status; partial = at least one platform unknown; unknown = no platform resolved; invalid_input = not a valid domain; skipped = not checked (run limit, free plan limit or run stopped). Only ok is charged.
reason
Optional
Why the row is not ok (for example some_platforms_unknown, invalid_domain, free_plan_run_limit, run_budget_exhausted). null when ok (except "redirect_to_unrelated_domain", which can accompany ok).
isRunningAds
Optional
true = ads found on at least one selected platform; false = not found on any selected platform within its window and scope; null = not known.
platformsWithAds
Optional
Platforms with ads found: google, meta, linkedin.
totalAdsCount
Optional
Sum of the known ad counts of the selected platforms (Google count is an estimate). null when no count is known.
Optional
Google Ads Transparency Center result for ads pointing to the entered domain (shown in the last 7 days, any region): status (active / not_found / unknown), confidence, reason, ad library link, checked targets (the entered domain only), ad count estimate, ad account name (often an agency — not the legal company name; withheld when it looks like a private person), advertiser ID, verified flag, number of ad accounts, third-party account flag and basis, other third-party advertisers, first/last seen, evidence ad, scope and sample ads. null when Google was not selected.
meta
Optional
Meta Ad Library result (Facebook & Instagram, ads with status ACTIVE on the check date): status, confidence, reason, ad library link, page ID and name, how the page was matched (high = linked from the website or same alias; legal_name = page name equals the full legal company name stated on the website, e.g. "… GmbH"; ad_domain = ads link to the domain; medium = name only; alias_no_ad_history = the website links a Facebook page that has no ads in the library), active ad count, first seen, evidence ad, scope and sample ads. A linked page the library does not know gives not_found with confidence medium (reason linked_page_no_ad_history, charged) only when every search succeeded; when a search fails or a similarly named page runs ads without a verifiable link, the result is unknown (meta_page_unresolved, not charged). When the keyword search for the domain returns more unrelated ads than the Actor reads, the result is unknown (pagination_unresolved, not charged), even if the linked page has no active ads. null when Meta was not selected.
Optional
LinkedIn Ad Library result (beta; ads that ran in the last 30 days, ending yesterday): status, confidence, reason, ad library link, match basis, company ID, ad count, first/last seen, evidence ad (dateSource "query_window" when LinkedIn returns no dates), scope and sample ads. null when LinkedIn was not selected.
company
Optional
Light company profile: name, nameWithheld, nameSource (og_site_name, json_ld, linkedin, google_ad_account, title or domain), website, linkedinUrl, industry, employeeRange, hqCountry, source (linkedin or homepage). Never lists people. null when not requested.
checkedAt
Optional
When the domain was checked (ISO 8601, UTC).
adapterVersions
Optional
Versions of the homepage and platform checks used for this row.
billed
Optional
true when this row was charged as one checked domain (status ok in a pay-per-event run).
