# Google Ad Details API

`GET /v1/ad-library/google/ad-details`

## Request

- Base URL: `https://api.captapi.com`
- URL: `https://api.captapi.com/v1/ad-library/google/ad-details`
- Auth: one of:
  - HTTP bearer
  - API key in header `X-API-Key`

Google publishes spend and impression ranges only for election ads; commercial advertisers omit both.

Google publishes spend and impression ranges only for election ads in regions that require disclosure; commercial advertisers omit both. isActive is derived from lastShown — true when the creative was seen within 7 UTC days. Paste a Google Ads Transparency URL with both AR… advertiser and CR… creative IDs. This is ID lookup, not a richer scrape: same commercial SearchCreatives payload as a company-ads row. Response id and advertiser.id always match the request. Flat 2 credits native; the fallback path is capped at 5.
