Access and Pricing

🚧
v0.2 of Gamma's API offerings will be deprecated on Jan 16, 2026.
Please move to v1.0 of Gamma's API endpoints before this date to avoid disruption.

Access the API

The API 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

Usage is currently capped at 50 generations/hour/user, and is subject to change.
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 as 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.
