Segmind ESRGAN API
What Segmind ESRGAN API is
Segmind ESRGAN API is an AI image super-resolution service available through an API and web interface. It enlarges images while preserving their source composition and content, with 2x, 4x, and 8x scale options; 8x is the maximum listed factor and larger outputs cost more. JPEG, PNG, and WEBP outputs are supported, with JPEG as the default. Quality defaults to 95 and accepts values from 10 to 100. Requests use an x-api-key header, and asynchronous processing supports submission, status polling, and result retrieval for one hour. A browser playground allows runs without code, while a Python SDK includes asynchronous methods. JavaScript and TypeScript SDKs are described as coming soon, with HTTP suggested meanwhile. Serverless usage is listed at $0.01, paid once, billed per GPU second. Pro, Business, and Scale monthly plans cost 39.00, 99.00, and 599.00 USD respectively. There is no free plan.

Verdict
Segmind ESRGAN API provides multiple upscale factors, output formats, and API workflows. Its paid plans and usage model should be considered alongside the lack of a free plan and current JavaScript SDK status.
