Segmind ESRGAN API review
A developer-focused API for controllable AI image upscaling from 2× to 8×.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Segmind ESRGAN API is a cloud image super-resolution service for developers and teams that need to enlarge images programmatically. It accepts an image URI and returns an upscaled image through a REST API, with selectable 2×, 4×, or 8× scaling. JPEG, PNG, and WEBP output formats are supported, while output quality can be set from 10 to 100. API-key authentication, synchronous requests, asynchronous submit-and-poll requests, and Python SDK support make it suited to applications that need image enhancement within an automated workflow.
Pricing is usage-based for the model-specific API: the Serverless plan starts at $0.0072 per GPU second and includes pay-as-you-go credits, auto-scaling, universal credits, and immediate deployment. Dedicated Cloud adds a dedicated GPU, reserved capacity, custom endpoints, and enterprise support. Segmind also lists Flexible, Pro, Business, Scale, and Enterprise tiers. Pro costs $39 per month, Business costs $99 per month, and Scale costs $599 per month; their listed additions include storage, RPM limits, credits, PixelFlow features, usage analytics, and different support response times. Enterprise includes custom solutions, a 99.99% SLA, dedicated Slack support, and SOC 2 compliance.
The main fit is teams integrating AI upscaling into software, services, or internal pipelines rather than users seeking a standalone image editor. The API covers common output formats and gives developers control over scale and quality, while asynchronous requests can support workflows that do not require an immediate response. Choose it when API access, Python support, and usage-based deployment matter. Consider an alternative if you need a free starting tier or a broader end-user editing workspace.
