Fal.Ai Media Generation
Generate images, videos, and transcripts using fal.ai's API with support for FLUX, Stable Diffusion, Whisper, and more.
Features
- Queue-based async generation (submit → poll → result)
- Support for 600+ AI models
- Image generation (FLUX, SDXL, Recraft)
- Video generation (MiniMax, WAN)
- Speech-to-text (Whisper)
- Robust error handling with clear messages
- Stdlib-only dependencies (no external packages)
Setup
- Get your API key from https://fal.ai/dashboard/keys
- Configure with:
export FAL_KEY="your-api-key"
Or via clawdbot config:
clawdbot config set skill.fal_api.key YOUR_API_KEY
Usage
Interactive Mode
You: Generate a cyberpunk cityscape with FLUX
clawd: Creates the image and returns the URL
CLI
# Basic image generation
python3 fal_api.py --prompt "A cyberpunk cityscape" --model flux-schnell
# High-quality with custom settings
python3 fal_api.py --prompt "A sunset over mountains" --model flux-dev \
--guidance-scale 5.0 --steps 20
# Reproducible (same seed = same image)
python3 fal_api.py --prompt "A robot" --seed 12345
# List available models
python3 fal_api.py --list-models
Python Script
from fal_api import FalAPI
api = FalAPI()
# Generate and wait
urls = api.generate_and_wait(
prompt="A serene Japanese garden",
model="flux-dev"
)
print(urls)

CLI Examples
# Basic image
python fal_api.py --prompt "A sunset over mountains" --model flux-schnell
# High-quality with custom settings
python fal_api.py --prompt "A cyberpunk city" --model flux-dev \
--guidance-scale 5.0 --steps 20
# Reproducible (same seed = same image)
python fal_api.py --prompt "A robot" --seed 12345
Error Handling
The skill provides clear error messages for common issues:
- 401 Unauthorized → Invalid API key
- 429 Rate Limit → Wait and retry
- 402 Payment Required → Insufficient credits
Requirements
- Python 3.7+
- No external dependencies (uses stdlib only)
