Validation errors, `401`/`402`/`429` rejections and `5xx` failures are free; `not_found` is charged ([how charging works](https://lurkapi.com/docs.md#credits)). - **MCP tool:** `google_company_ads` on `https://api.lurkapi.com/mcp` - **Freshness:** responses are cached for up to 12 hours - **Try it live:** https://lurkapi.com/docs/google/company-ads#try (no signup; free tool: [Google Ads Transparency search](https://lurkapi.com/free-tools/google-ads-transparency)) - **Platform:** [Google](https://lurkapi.com/docs/google.md) (adstransparency.google.com) - **Web page:** https://lurkapi.com/docs/google/company-ads ## When to use this Use it to study a competitor's Google and YouTube ads: formats, run dates and how long each ad has run. Pass `domain` (e.g. nike.com, every advertiser promoting it) or `advertiser_id` from search advertisers (google_search_advertisers). Filter by region, platform, format and date range. `topic=political` lists election ads with their spend and impressions, and needs a `region`. For an ad's text, landing page and per-country stats, pass its ids to ad details (google_ad). **Pagination.** Up to 100 ads per page. Pass `cursor` back with the same filters for the next page; it's null on the last page. Date ranges that start more than about a year back come back empty. ## Parameters All parameters go in the query string. | Name | Type | Required | Default | Allowed values | Description | Example | | --- | --- | --- | --- | --- | --- | --- | | `domain` | string | no | | | The advertiser's website, e.g. `nike.com`.

Ask in plain English, for example: Ask Claude: ```text Use LurkAPI's google_company_ads with domain "nike.com", region "US" and summarize what you find. ``` Claude calls `google_company_ads` with arguments like these, and each call costs 1 credit: Tool arguments: ```json { "domain": "nike.com", "region": "US" } ``` Tool results skip nulls and empty lists to save tokens. --- Previous: [Search Google advertisers](https://lurkapi.com/docs/google/search-advertisers.md) · Next: [Google ad details](https://lurkapi.com/docs/google/ad.md)
