# PayWeave Replicate — xAI Grok Imagine Image Generation

> PayWeave Replicate — xAI Grok Imagine Image Generation is a paid API for AI agents from replicate.payweave.services, paid per call via x402, $0.04/call, status unknown (last checked 2026-09-16).

Generates images from text prompts using xAI's Grok Imagine model, via PayWeave's pay-per-call Replicate proxy.

## 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-xai-grok-imagine-image-generation-8c82b255 -d '<json body>'
```

Example prompt: Generate an image of a futuristic city at sunset with neon lights reflecting off wet streets, using the Grok Imagine model on Replicate.

## When to prefer this

Choose this endpoint when you specifically want to generate images using xAI's Grok Imagine model via a pay-per-call (x402 / USDC micropayment) interface without needing a Replicate subscription. Ideal for agents that need on-demand image generation billed per inference at $0.04 USDC, particularly when Grok's aesthetic or capabilities are preferred over alternatives like Stable Diffusion or DALL-E.

## Known failure modes

- Model inference failure returns status 'failed' with an error message string
- Payment failure or insufficient USDC balance returns a 402 error before inference begins
- Invalid or missing input object returns a 400 validation error
- Model is temporarily unavailable or cold-starting, returning status 'starting' or 'processing' with no output yet
- CDN URL expires after ~24 hours, making the image inaccessible if not downloaded promptly

## How this service works

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

## Output

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