# PayWeave Replicate – FLUX Schnell Image Generation (Pay-per-call)

> PayWeave Replicate – FLUX Schnell Image Generation (Pay-per-call) is a paid API for AI agents from replicate.payweave.services, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Generates images from text prompts using Black Forest Labs' FLUX Schnell model via Replicate, billed per call at $0.01 USDC.

## Facts

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-schnell-image-generation-pay-per-call-0036de8a -d '<json body>'
```

Example prompt: Generate an image of a golden retriever surfing at sunset on a tropical beach using the FLUX Schnell model — fast quality, photorealistic style.

## When to prefer this

Choose this endpoint when you need fast, high-quality text-to-image generation using Black Forest Labs' FLUX Schnell model specifically, and want pay-per-call pricing with crypto (USDC) billing via x402 rather than a subscription. Ideal for agents that generate images on-demand without a standing Replicate account.

## Known failure modes

- Model inference fails: status='failed' with non-null error string
- Payment rejected or insufficient balance: HTTP 402 before prediction starts
- Invalid or missing 'input' object: 400-level validation error
- Output URL expires after ~24h TTL: image no longer accessible
- Model is starting/queued: status='starting' or 'processing' with no output yet
- Prediction canceled: status='canceled' with null output

## How this service works

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

## Output

Returns a Replicate prediction object containing a unique prediction ID, the model name, a status field (succeeded/failed/canceled/processing/starting), the output as a CDN-hosted image URL (valid ~24 hours), timing metrics (predict_time, total_time), timestamps, and the USD amount charged for the call.
