What it does

This endpoint provides access to Stability AI's Upscale Conservative model through the Locus MPP (Micropayment Protocol) gateway. It increases image resolution while preserving fine details with minimal AI hallucination, making it suitable for photographs and artwork where fidelity to the original is critical. You supply a source image and a text prompt describing the content, and the service returns an upscaled version. A creativity parameter (0–1, default 0.35) controls how much detail enhancement the model adds.

The endpoint is part of a broader Stability AI suite hosted on Locus MPP that includes text-to-image generation (Ultra, Core, SD3), editing tools (erase, inpaint, outpaint, search-and-replace, search-and-recolor), background removal and replacement, style transfer, sketch-to-image, 3D model generation, and audio generation. Each endpoint is individually priced and settled via the Tempo L2 payment method using pathUSD (6 decimals). The Upscale Conservative endpoint costs 460,000 base units, which equals $0.46 per call.

The API accepts POST requests with a JSON body. Required fields are `image` (the source image) and `prompt` (a description of the image content). Optional fields include `negative_prompt`, `creativity` (0–1), `output_format` (jpeg, png, or webp), and `seed` for reproducibility. Note that the probe returned 404 on HEAD/GET — this is expected since the endpoint only accepts POST requests. The OpenAPI spec and payment metadata are well-defined, confirming the endpoint is configured and available for purchase.

Capabilities

Use cases

  • —Upscaling product photos for e-commerce listings while preserving original detail
  • —Increasing resolution of archival or scanned images without introducing artifacts
  • —Preparing low-resolution assets for print by enlarging them conservatively
  • —Batch upscaling user-uploaded images in a content pipeline

Fit

Best for

  • —Developers needing faithful image upscaling with minimal hallucination
  • —Workflows where preserving original image detail is more important than creative enhancement
  • —Agent-driven pipelines that need pay-per-call image processing without API key management

Not for

  • —Creative upscaling where significant AI-generated detail is desired (use Upscale Creative instead)
  • —Real-time or latency-sensitive applications — this is an async-capable API
  • —Free or high-volume bulk processing on a tight budget at $0.46 per image

Quick start

curl -X POST https://stability-ai.mpp.paywithlocus.com/stability-ai/upscale-conservative \

Quality

The OpenAPI spec is comprehensive with full request schema, payment metadata, and pricing. However, the endpoint probe returned 404 (expected for POST-only routes probed with HEAD/GET), no response schema or example response is documented, and crawled pages returned no useful documentation. No live 402 challenge was captured for this specific endpoint.

Warnings

  • —Probe returned 404 on HEAD and GET — endpoint is POST-only; liveness not confirmed via 402 challenge
  • —No response schema documented — output format and structure must be inferred from Stability AI's upstream API docs
  • —Currency address 0x20c000000000000000000000b9537d11c60e8b50 assumed to be pathUSD with 6 decimals based on Tempo L2 convention; not independently verified
  • —All crawled pages returned 404 with no documentation content
