Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability payweave-fal-flux-pro-v1-1-image-generation-59a0d683 -d '<json body>'
```

Example prompt: Generate an image of a misty Japanese forest at dawn with golden light filtering through tall cedar trees — use FLUX Pro v1.1 for the highest quality result.

## When to prefer this

Choose this endpoint when you need high-quality FLUX Pro v1.1 image generation with no subscription required, paying only per call in USDC via x402. Ideal for agents that need occasional image synthesis without committing to a monthly plan, or that operate in crypto-native payment environments. Prefer over direct fal.ai when you need x402/micropayment compatibility.

## Known failure modes

- Payment failure: x402 payment not accepted or insufficient USDC balance
- Input validation error: missing or malformed 'input' object in request body
- Model error: fal.ai inference failure, error field populated with details
- Rate limiting: too many concurrent requests to the fal.ai backend
- CDN URL expiry: returned image URLs expire after ~24 hours and cannot be retrieved again
- Timeout: sub-second inference not guaranteed under heavy load

## How this service works

Sub-second generative AI inference — image, video, audio.

## Output

Returns a JSON object with a fal request ID, the model used, status ('succeeded'), a model-specific output field containing one or more CDN-hosted image URLs (valid for ~24 hours), inference time in seconds, and the USD amount charged for the call.
