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-replicate-flux-1-1-pro-image-generation-1123820a -d '<json body>'
```

Example prompt: Generate an image of a misty mountain valley at sunrise with golden light filtering through pine trees, photorealistic style — use FLUX 1.1 Pro and return the image URL when it's done.

## When to prefer this

Choose this endpoint when you need to generate images specifically with Black Forest Labs' FLUX 1.1 Pro model via Replicate, want pay-per-call pricing with no subscription commitment, and are operating in an x402/USDC payment environment. Prefer this over general Replicate API access when you want a pre-wired payment gateway. Use when FLUX 1.1 Pro quality is specifically required over other image generators.

## Known failure modes

- Payment failure or insufficient USDC balance returns HTTP 402
- Invalid or missing 'input' object causes validation error
- Model returns status 'failed' with error string if inference fails
- Generated CDN image URLs expire after approximately 24 hours
- Model may return status 'processing' or 'starting' if not yet complete, requiring polling
- Network timeout on long-running predictions
- Malformed input parameters specific to FLUX 1.1 Pro may cause silent failures

## How this service works

Run open-source AI models — image, video, audio.

## Output

Returns a prediction object including a Replicate prediction ID, the model name, status (succeeded/failed/canceled/processing/starting), CDN-hosted image URL(s) with ~24h TTL, timing metrics (total_time and predict_time in seconds), timestamps for creation and completion, and the USD amount charged for the call. On failure, an error string is populated instead of output.
