Generate and manage Full Campaigns (FC) from a product URL, a manual product (name+description+images), or text-only. Each campaign generates (defaults): 6 image ads (3 with text + 3 clean), 4 video ads, 3 UGC presenter videos, 12 Google ad copy variations, 10 keywords, plus social captions. Tier (base/pro/premium) changes credit cost and UGC render quality, not asset counts. Re-render one image (regenerateAsset, credits only), download, or remove a campaign from your library. Actions: eligibility, create, status, assets, downloadAll, regenerateAsset, deleteFromLibrary. Call adgpt_capabilities with the operationId to see an action's parameters.
