# Credits

Read the authenticated account's credit balance and purchase limits, or create a checkout link without completing payment.

Blotato credits pay for AI generations such as videos and images. Use these endpoints to check your remaining credit balance, see current pricing, and buy more credits. Two endpoints:

* [Get Credit Balance](#get-credit-balance) — `GET /v2/credits`
* [Buy Credits](#buy-credits) — `POST /v2/credits`

Credits belong to a single account and are non-transferable. Confirm the account email from [Get Credit Balance](#get-credit-balance) before you buy, so the credits land on the account you intend.

## Buy Credits

### Endpoint

**URL:** `/credits`

**Method:** `POST`

### Description

Creates a Stripe Checkout link to buy credits. Creating the link does not charge anything. The account owner opens the link in a browser and completes payment there, and the purchased credits land on this account. Stripe creates an invoice for the credit purchase after checkout succeeds. Buy between 1,000 and 10,000 credits per request.

Confirm the account email from [Get Credit Balance](#get-credit-balance) first, since credits are non-transferable between accounts.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://help.blotato.com/rest-api-reference/credits.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
