# Review access and pricing

### Quick reference

* ChatGPT and Claude connectors work on all plans.
* API keys are available on Pro, Ultra, Teams, and Business plans.
* Credit usage is returned in the `credits` field on `GET /v1.0/generations/{generationId}`.
* Auto-recharge is the safest way to prevent failed generations due to exhausted credits.

### Access

#### API keys (Zapier, Make, n8n, direct integration)

API key access is available on Pro, Ultra, Teams, and Business plans. Generate an API key from [Settings > API Keys](https://gamma.app/settings/api-keys). View [pricing plans here](https://gamma.app/pricing).

#### Connectors (ChatGPT, Claude)

Connectors are available on all plans, including Free and Plus. No API key required — connect directly from [ChatGPT or Claude](https://developers.gamma.app/connectors/connectors-and-integrations) and authenticate with your Gamma account. Generations via connectors charge credits the same way as API calls.

### Usage and pricing

* API billing uses a credit-based system. 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 [Settings > Billing](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`           | 1-3 credits/card (varies by the text generation model Gamma selects internally)                                         |
| AI image model  | `imageOptions.model` | Standard: 2-15 credits/image. Advanced: 20-33 credits/image. Premium: 34-75 credits/image. Ultra: 30-125 credits/image. |

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

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.
