Access and Pricing

Access

API access is available to subscribers on Pro, Ultra, Teams, and Business plans. View pricing plans here.
To get started, you can generate an API key through your account settings as shown below.

Usage and pricing

API billing is conducted using a credit-based system, and higher tier subscribers receive more monthly credits.
If you run out of credits, you can upgrade to a higher subscription tier, purchase credits ad hoc, or enable auto-recharge (recommended) at https://gamma.app/settings/billing

How credits work

Credit charges are determined based on several factors and are returned in the GET response.

Feature	API parameter	Credits Charged*
Number of cards	`numCards`	1-5 credits/card
AI image model	`imageOptions.model`	Basic models: 2 credits/image Advanced models: 7-20 credits/image Premium models: 20-70 credits/image Ultra models: 30-125 credits/image

*Credit consumption rates and the actions that consume credits are subject to change.

Card credit costs vary depending on the AI model used for text generation. Template-based generations (POST /generations/from-template) may cost slightly more per card than standard generations.

Illustrative scenarios

Deck with 10 cards + 5 images using a basic image model = ~20-60 credits
Doc with 20 cards + 15 images using a premium image model = ~320-1070 credits
Socials with 30 cards + 30 images using an ultra image model = ~930-3900 credits

Both standard generations (POST /generations) and template-based generations (POST /generations/from-template) consume credits. Credit usage details are returned in the credits field of the GET /generations/{generationId} response, showing deducted and remaining values.
