How this service works
Sub-second generative AI inference — image, video, audio.
Output
Returns a JSON object containing a fal request ID, model name, status ('succeeded'), a CDN-hosted image URL (fal-hosted, valid for ~24 hours), inference time in seconds, and the USD amount charged for the call. The image URL points directly to the generated image.
Example use cases
Example prompt
“Generate a photorealistic image of a misty mountain lake at golden hour with pine trees reflected in the water — use FLUX Pro Ultra for the highest quality output.”
Technical details
Endpoint
POSThttps://fal.payweave.services/models/fal-ai/flux-pro/v1.1-ultra/runWhen to prefer
Choose this endpoint when you need top-tier image quality from FLUX Pro v1.1 Ultra specifically, want pay-per-call billing with no subscription, need sub-second to fast inference with a CDN-hosted result URL, and are operating in a crypto-native or x402-payment environment. Prefer over other fal endpoints when FLUX Pro Ultra quality is explicitly required over standard or cheaper models.
Side effects
- Insufficient USDC balance causes 402 payment required error before inference begins
- Invalid or missing input object returns 400 bad request
- Model overload or timeout may return an error string in the error field with a null output
- Generated image URL expires after ~24 hours making cached links stale
- Malformed prompt or unsupported parameters may cause inference failure with error details in response
