How this service works

Locus public pay-per-use API

Output

Returns a JSON object with a success flag, a request ID and status URL for async retrieval, and payment settlement details showing USDC charged and authorized. The generated image data is nested under the 'data' field.

Example use cases

AI concept art for game design

“Create a digital-art style image of a futuristic cyberpunk cityscape at night, in 16:9 aspect ratio, PNG format, and make sure to exclude any daylight or natural scenery.”

Square product lifestyle photography

“Generate a photorealistic 1:1 square image of a minimalist wooden desk with a coffee cup and open notebook, photographic style preset, JPEG output — no clutter or people in the background.”

Portrait illustration for social media

“Generate a digital-art portrait of a confident woman with flowing hair and vibrant colors in 9:16 portrait format as a PNG, excluding any text overlays or watermarks.”

When to prefer

Choose this endpoint when you need fast, affordable text-to-image generation via Stability AI's core model with micropayment billing (no API key setup required — pay per call in USDC via x402). Prefer it over direct Stability AI API calls when you need frictionless pay-per-use access without subscription management, and when style presets and aspect ratio control are sufficient for your use case.

Side effects

Invalid or missing prompt returns a 400 error
Unsupported aspect_ratio or output_format enum value causes a validation error
Insufficient USDC balance or payment failure returns a 402 Payment Required error
Seed value out of acceptable range may be rejected
Request timeout if generation takes longer than expected; use the statusUrl to poll for completion
If the prompt violates content policy, generation may be refused
