GET

Advertiser Search

Search the Google Ad Transparency Library for advertisers to get their advertiser id. Pass region for non-US advertisers, like AU or CA.

Credit cost

Default: 1 credit

How charges are determined

Cost is decided per call, not per endpoint: the same operation can cost different amounts depending on what it returns.

A call that fails costs 0 credits. A result served from cache costs 0 credits.

`default` is the cost when no rule matches. Rules are evaluated in order and the first whose conditions all hold wins.

A `when` condition is one of: `param` (the request parameter is true), `outcome` (the classifier's outcome), `empty` / `nonEmpty` (a response field is empty and absent, or a non-empty array or string), `flag` (a response field is exactly true).

A cost of `{ perStartedMinute: n, of: [fields] }` is n x max(1, ceil(seconds / 60)), so even a short result bills at least one minute.
