Frequently asked questions
What is an ad creative API?
An endpoint that composes an advertising visual around your product photo — background, light, typography — with your headline written on the image, in the format of the channel you post on.
Is the headline spelled exactly?
Yes — the headline field is written on the visual verbatim, so spelling and capitalisation are yours.
How much does it cost?
1 credit on the standard tier, 3 on pro. Credits come with plans and packs; a failed generation is always refunded.
