Usage

fal api <model_id> [key=value ...]

Arguments:

Argument Description
model_id The model endpoint to call (e.g., fal-ai/flux/schnell)
params Key-value pairs for the request body (e.g., prompt="a sunset")

Examples

Generate an image:

fal api fal-ai/flux/schnell prompt="a cat wearing sunglasses"

The CLI shows real-time status updates (queued, in progress) and logs while the request is processing, then prints the result. Nested parameters: Use bracket notation for nested values:

fal api fal-ai/flux/schnell prompt="a sunset" image_size[width]:=1280 image_size[height]:=720

Use := for non-string values (numbers, booleans):

fal api fal-ai/flux/schnell prompt="a sunset" num_images:=4 seed:=42

Streaming endpoints: If the model ID ends with /stream, the CLI streams output as it’s generated:

fal api fal-ai/any-llm/stream prompt="What is the meaning of life?" model=google/gemini-flash-1.5
