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. 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?

That is Google's limit, not a scrape miss. 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. Image/video rows omit text/headline/cta/landingUrl (copy lives in the asset). Text-format rows keep those keys as null because the format is inferred from no media — ATC does not ship the copy. Use sort=first_shown to see isActive:false.

Why is ads[] empty — and did I pay?

Read resolution. not-in-library means Google's library has no matching advertiser (a domain like supermaker.ai). resolved-no-ads means we found the AR… entity and ATC answered with zero creatives — verified without the country filter too, so a region-tagged entity does not read as empty. resolved-filtered-out means a start_date/end_date window dropped every creative. All three are 0 credits — two byte-identical empties no longer bill differently. A proxy timeout mid-fetch is never sold as resolved-no-ads: that path retries on the extended tier and 502s only when every tier fails.

advertiser-search said adsCount 4 — why did company-ads return 0?

It should not anymore. That mismatch had one honest cause and one bug. Honest: country is a soft filter — when the AR entity's creatives carry no region tag for your country we automatically retry without the filter, so region-tagged inventory still comes back. Bug (fixed): a proxy timeout during the creatives pull used to ship ads=[] with resolution=resolved-no-ads; a transport failure now falls through to the extended tier instead of masquerading as an empty advertiser.

Why does otherMatches list a second advertiser?

A name or domain can match more than one Google AR… legal entity (Base44 vs Base44 Ltd). ads[] and adsCountEstimate are only resolvedAdvertiser. otherMatches is the rest — pass advertiser=AR… to fetch one of them. We do not merge those accounts.

What does resolution: null mean?

Ads were returned. The field is always keyed; null is not a leftover. Empty lists use not-in-library | resolved-no-ads | resolved-filtered-out.

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. Selected profile endpoints also accept cacheMaxAge=1d|3d|7d|14d|30d. Use it for analytics, monitoring, and content automation.
