How this service works
Pay-per-generation AI image and video creation. No subscriptions ever.
Output
Returns a JSON object with success:true, a jobId string, status:'pending', and a type field. The agent must poll a separate job-status endpoint using the jobId to retrieve the final generated image once processing completes.
Example use cases
Example prompt
“Generate a high-quality 1024x1536 portrait image of a misty forest at sunrise with golden light filtering through ancient redwood trees — use PNG format with an opaque background and no compression.”
Technical details
Endpoint
POSThttps://stablestudio.dev/api/generate/gpt-image-1.5/generate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need GPT Image 1.5 quality specifically — it offers improved fidelity over GPT Image 1.0. Prefer over Flux 2 Pro when OpenAI's photorealistic style is desired. Use when transparent backgrounds, flexible output formats (PNG/JPEG/WebP), or variable compression are needed. Best for high-detail, prompt-faithful image generation with async job delivery.
Side effects
- Invalid or empty prompt returns validation error
- Unsupported size/quality/format enum value causes 400 bad request
- Payment not provided or insufficient USDC balance returns 402 Payment Required
- Job creation fails server-side, returning success:false
- Rate limiting or capacity issues may cause 429 or 503 responses
- Moderation rejection if prompt violates content policy even at low moderation setting
