TL;DR

List an advertiser's Google Ads Transparency creatives — AR chain, cursor, dates, sort (2 credits). The Google Company Ads API (Google Ad Library) is a single authenticated GET request to /v1/ad-library/google/company-ads that responds with clean JSON and costs 2 credits. Pass cache=true for a free 24h cache hit; default is always fresh. Start with 100 free credits — no credit card.

What is the Google Company Ads API?

Pass an advertiser name, domain (nike.com), or AR… id from advertiser-search and get public commercial creatives as clean JSON. Response includes resolvedAdvertiser{id,name,url} (the entity actually queried), stable nulls for text/headline/cta/landingUrl/spend/impressions when ATC withholds them, firstShown/lastShown, adFormat, and media[]. Supports country/region, start_date/end_date, sort=last_shown|first_shown, cursor pagination (nextCursor + hasMore), and adsCountEstimate. Prefer advertiser=AR… from /google/advertiser-search for a deterministic chain. Spend/impressions are usually null for commercial ads (Google only publishes them for political). Flat 2 credits on the native path (max 200 per page).

What you get

Bulk list of company ads with metadata
Dates, URLs, and engagement fields when available
Configurable result limit
Ideal for monitoring and content pipelines

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.
