Higgsfield charges successful generation requests to your account balance. The exact cost depends on the selected model and parameters.

​
Balance expiration

Funds added to your account balance expire one year after they are added. Plan purchases and usage with this expiration period in mind.

​
Estimate a request

Use the estimate endpoint with the same model parameters before submitting generation:
The values above illustrate the response format. Use the estimate returned for your authenticated account as the authoritative amount.

​
Failed and moderated requests

Requests ending as failed or nsfw are not charged. If an amount was reserved when the request was accepted, it is refunded automatically.

​
Canceled requests

A request can be canceled only before processing starts. A successfully canceled queued request is refunded.

​
Output retention

Request files are kept for seven days after the request finishes, then deleted. The status response and the webhook include expires_at, the time of deletion. Download completed files to your own storage for long-term retention. To keep data for less time, send the Hf-Expires-After header (one hour or more) or ask Higgsfield to set a retention period for your account. To remove a finished request immediately, call DELETE /requests/{request_id}. Billing records are kept in both cases. See Data retention and deletion.
