Retool introduced several features to help Enterprise organizations manage AI token spend when using their own API key for AI resources.

Use the new Get BYOK AI token usage endpoint to measure the number of tokens consumed for each AI resource that uses your own key. You can view the number of tokens consumed by resource, user, and surface area.

In addition, you can also view BYOK AI token usage in Settings. Navigate to the Usage Analytics page, and click the AI tab. You can filter AI usage by model, user, and feature.

You can now delete workflows programmatically using the DELETE /api/v2/workflows/{workflowId} endpoint in the Retool REST API.

To use this endpoint, your API token must have the workflows:write scope. The endpoint only supports deleting standard workflows—deleting agents and functions via the API is not supported.

Refer to the Retool API reference for full endpoint details, including request parameters and error responses.

Retool has two new improvements to the API:

• A new per-instance API reference is now available at {your-instance}/reference. The reference is available on all cloud instances and served locally by self-hosted deployments within its VPC—no internet connection required. The API reference reflects only the API version running on your instance and always matches what's available to you.
• The API version now tracks the Retool release version. The Retool API version now corresponds to your instance's release version. This makes it easier to track Retool API changes whenever your instance is updated.
