How this service works

Generative AI platform for images, 3D models, and audio — text-to-image, editing, upscaling, and more.

Output

Returns a JSON object containing a 'data' field with the generated image result, a 'payment' object confirming the settled USDC amount, a 'request' object with a unique request ID and a status URL for polling, and a 'success' boolean flag.

Example use cases

Architectural concept restyling

“I have a sketch of a building layout — can you generate a photorealistic rendering of it as a modern glass skyscraper using Stability AI's structure control? Keep the composition tight (control strength 0.9) and exclude cartoon or sketch elements. Output as JPEG.”

Product photo style transfer

“I have a product shot of a sneaker. Generate a new image with the same structure and shape but styled as if it's floating in a futuristic neon space environment — control strength 0.7, no people or hands, output as PNG.”

Portrait artistic transformation

“Use this portrait photo as a structure reference and generate a renaissance oil painting version of it with the same pose and framing. Set control strength to 0.75, exclude modern clothing references, and output as WebP.”

When to prefer

Choose this endpoint when you need to preserve the structural composition or layout of an existing image while generating entirely new visual content driven by a text prompt. It is ideal for style transfer with structural fidelity, architecture or product restyling, and pose-preserving portrait transformations. Prefer this over unconditioned text-to-image endpoints when the output layout must mirror a reference, and over inpainting endpoints when the entire image appearance — not just a region — should change.

Side effects

Invalid or unreadable reference image URL — returns error indicating image cannot be processed
control_strength outside 0–1 range — validation error
Unsupported output_format value (must be jpeg, png, or webp) — schema validation failure
Insufficient USDC payment or payment failure via x402 protocol — 402 Payment Required response
Prompt or negative_prompt too long — content or length validation error
Rate limiting or upstream Stability AI API unavailability — 503 or timeout error
