freepik/ai-image-upscaler-precision-v2 with the Comfy Router API. Freepik provides the model; Router gives it the shared authentication and request route below.
Quick start
Create a key at platform.comfy.org/profile/api-keys and export it asCOMFY_API_KEY. The Python and TypeScript snippets use the Comfy SDKs (pip install comfy-sdk, npm install @comfyorg/sdk); the cURL snippet is the same call over raw HTTP.
Model ID: freepik/ai-image-upscaler-precision-v2
Endpoint: POST https://api.comfy.org/v2/models/freepik/ai-image-upscaler-precision-v2
Schema

integer
Image scaling factor. Determines how much larger the output will be compared to input.Range:
2 to 16integer

Image sharpness intensity control. Higher values increase edge definition and clarity.Range:
0 to 100integer
default:"7"

Input
Before you ship
Save oneIdempotency-Key for each call and reuse it for retries. Router can hold the connection for up to 10 minutes. The SDKs handle authentication; raw HTTP clients send the headers themselves.
When a request fails, Router sends an X-Comfy-Error-Type response header explaining why. A 422 means Router rejected the input before calling the provider. Download generated assets promptly because result URLs can expire.
Headers
Authentication, idempotency, request IDs, error buckets, retry pacing, spend limits.
Using the Router API
Model discovery, validation errors, retries, and billing.
