flux generate image

POST

Maintainer:Not configured

Overview

The /flux/v1/{model} endpoint allows you to generate images based on prompts and parameters.

⚠️ Important Note:

Due to significant differences in parameter lists across Flux series models, please refer to the official documentation for detailed usage instructions. The parameter list provided here is for reference only.

After generation, you can use the /flux/v1/get_result endpoint to query generated images or monitor process status.

Because the image resources returned by BFL’s official service have a very short validity period, the images may expire in about 10 minutes. Please save the generated results promptly!
