Uses platform quota
Synchronous response
Reads public data

Parameters

exactly one of keywordSeed | urlSeed | siteSeed | keywordAndUrlSeed. Unlike googleAds:search, this route DOES accept pageSize — use it, the unbounded response is thousands of ideas. Volumes are BUCKETED for accounts with little spend — the same limitation the Keyword Planner UI has, not an API fault
