Real-ESRGAN — hosted API access

This repository is not the model weights — it documents running Real-ESRGAN through a hosted API on apimodels.app, a multi-model gateway where one key and one OpenAI-compatible endpoint reach 110+ image, video, audio and language models.

Independent hosted-API integration. Not affiliated with or endorsed by the authors; does not redistribute their weights. All credit for the model is theirs.

What it does

The classic open image upscaler. Send a low-resolution image, get a sharper, larger one back.

Left: low-resolution input. Right: the upscaled result.

Use it via API

On apimodels.app the model is served as real-esrgan. Get a key at https://apimodels.app, then:

# 1) upload the image -> public URL
curl -X POST https://api.apimodels.app/v1/files \
  -H "Authorization: Bearer YOUR_API_KEY" -F "file=@input.jpg;type=image/jpeg"
# 2) upscale it
curl -X POST https://api.apimodels.app/v1/images/generations \
  -H "Authorization: Bearer YOUR_API_KEY" -H "Content-Type: application/json" \
  -d '{ "model": "real-esrgan", "image": "<publicUrl>" }'
# 3) poll GET /v1/images/generations?task_id=... until state == "completed"
