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 stablestudio-gpt-image-1-5-generate-6e476f97 -d '<json body>'
```

Example prompt: Generate an image of a futuristic cityscape at sunset with flying cars and neon lights, in 16:9 widescreen format at 2MP resolution, PNG format, with strict safety settings — use StableStudio's pay-per-generation GPT-Image-1.5 model.

## When to prefer this

Choose this endpoint when you need high-quality AI image generation using OpenAI's GPT-Image-1.5 model with flexible resolution (up to 4MP), multiple aspect ratios, and no subscription commitment — ideal for one-off or low-volume image creation tasks billed at $10 USDC per image.

## Known failure modes

- Invalid or empty prompt returns validation error
- Unsupported resolution or aspect ratio enum value returns 400
- Safety tolerance out of range (outside 1-5) returns validation error
- Payment of $10 USDC not completed or rejected causes request to fail
- Output quality outside 0-100 range causes validation error
- Server-side generation failure may return error status on job polling

## How this service works

Pay-per-generation AI image and video creation. No subscriptions ever.

## Output

Returns a JSON object with a jobId, status ('pending'), and success flag. The generation is asynchronous — the agent must poll or retrieve the result using the jobId to get the final image.
