Frequently asked questions

What does the Google Company Ads API do?

The Google Company Ads API lets you list items in bulk with metadata from a public Google Ad Library ad using one GET request to /v1/ad-library/google/company-ads. It returns clean JSON — no OAuth or infrastructure setup required.

How many credits does the Google Company Ads API cost?

Each successful call costs 2 credits. Pass cache=true to serve from the 24h cache (0 credits on hit); default is always fresh. Hits include cached + cachedAt. Selected profile endpoints also accept cacheMaxAge=1d|3d|7d|14d|30d. Failed or empty results are never charged.

Do I need a Google Ad Library API key or OAuth?

No. A single Captapi key works across every platform Captapi supports — YouTube, TikTok, Instagram, Facebook, Twitter/X, Reddit, Threads, Bluesky, Pinterest, LinkedIn, Rumble, Spotify, Kwai, and more. We handle proxies, rate limits, retries, and authentication for you.

Why are text/spend null on Google creatives?

Keys stay present as null for a stable parser. Google Ads Transparency rarely exposes copy or spend on commercial image creatives (spend/impressions are mostly political). landingUrl is filled when ATC embeds a destination. Use sort=last_shown and start_date/end_date for recent activity; page with nextCursor.

Is the Google Company Ads API suitable for production use?

Yes. It is a stable REST endpoint with predictable JSON and automatic retries. Pass cache=true to serve from the 24h cache (0 credits on hit); default is always fresh. Hits include cached + cachedAt. Selected profile endpoints also accept cacheMaxAge=1d|3d|7d|14d|30d. Use it for analytics, monitoring, and content automation.
