# PayWeave Replicate – GPT-Image-1.5 High Quality Image Generation

> PayWeave Replicate – GPT-Image-1.5 High Quality Image Generation is a paid API for AI agents from replicate.payweave.services, paid per call via x402, $0.28/call, status unknown (last checked 2026-09-14).

Generates high-quality images using OpenAI's GPT-Image-1.5 model via PayWeave's pay-per-call Replicate proxy, returning a CDN-hosted image URL.

## 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-gpt-image-1-5-high-quality-image-generation-a71f89df -d '<json body>'
```

Example prompt: Use GPT-Image-1.5 at high quality to generate an image of a misty Japanese mountain village at dawn with cherry blossom trees lining a stone path.

## When to prefer this

Choose this endpoint when you need high-quality image generation specifically from OpenAI's GPT-Image-1.5 model, want pay-per-call pricing with no subscription required, and need a Replicate-compatible prediction response format with CDN-hosted output URLs. Prefer this over generic image APIs when you specifically want GPT-Image-1.5's output quality and are comfortable with USDC micropayment billing via x402.

## Known failure modes

- Payment insufficient or x402 payment not included — returns 402 Payment Required
- Invalid or missing input object — returns validation error
- Model prediction fails on Replicate side — status returns 'failed' with error message
- CDN URL expires after ~24 hours — image no longer accessible after TTL
- Model is overloaded or starting — status may remain 'processing' or 'starting' for extended period
- Canceled prediction — status returns 'canceled' with no 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), a CDN-hosted image URL (valid ~24 hours) in the output field, timing metrics (total_time, predict_time), created_at and completed_at timestamps, an error field (null on success), and the USD amount charged for the call.
