The provider_params field lets you pass provider-specific parameters that aren’t part of Eden AI’s unified schema. This gives you access to advanced or niche options offered by individual providers without breaking the standard request format.

​
How It Works

Add a provider_params object to any Universal AI request. The contents are forwarded directly to the provider alongside the standard input fields. 
{
  "model": "{feature}/{subfeature}/{provider}[/{model}]",
  "input": {
    // Standard unified parameters
  },
  "provider_params": {
    // Provider-specific parameters passed through as-is
  }
}

​
Basic Example

import requests

url = "https://api.edenai.run/v3/universal-ai"
headers = {
    "Authorization": "Bearer YOUR_API_KEY",
    "Content-Type": "application/json"
}

payload = {
    "model": "image/generation/openai/dall-e-3",
    "input": {
        "text": "A futuristic city at sunset, cyberpunk style"
    },
    "provider_params": {
        "quality": "hd",
        "style": "vivid"
    }
}

response = requests.post(url, headers=headers, json=payload)
result = response.json()
print(result)

​
Common Use Cases

​
Image Generation — Style and Quality

Control output style and quality for image generation: 
import requests
import base64
from PIL import Image
from io import BytesIO

url = "https://api.edenai.run/v3/universal-ai"
headers = {
    "Authorization": "Bearer YOUR_API_KEY",
    "Content-Type": "application/json"
}

payload = {
    "model": "image/generation/openai/dall-e-3",
    "input": {
        "num_images": 1,
        "text": "A watercolor painting of a mountain landscape",
        "resolution": "1792x1024"
    },
    "provider_params": {
        "style": "vivid",
        "quality": "hd" #Default is standard
    }
}
response = requests.post(url, headers=headers, json=payload)
data = response.json()

img_url = data["output"]["items"][0]["image_resource_url"]
img_response = requests.get(img_url)
img = Image.open(BytesIO(img_response.content))
img.save('image.png')
img.show()

​
Text to Speech — Voice Settings

Pass provider-specific voice parameters: 
import requests

url = "https://api.edenai.run/v3/universal-ai"
headers = {
    "Authorization": "Bearer YOUR_API_KEY",
    "Content-Type": "application/json"
}

payload = {
    "model": "audio/tts/google/gemini-2.5-flash-tts",
    "input": {
      "voice": "achernar",
      "text": "Bonjour, j'adore la tourte.",
      "audio_format": "mp3"
    },
    "provider_params": {
      "language_code": "fr-FR",
      "prompt": "say this while crying"
    }
}

response = requests.post(url, headers=headers, json=payload)
print(response.json())

​
Important Notes

  • provider_params are not validated by Eden AI — they are passed directly to the provider. Invalid parameters may cause provider-side errors.
  • Available parameters vary by provider and feature. Refer to the provider’s own documentation for supported options.
  • provider_params only apply to the specific provider in the model string. If you switch providers, you may need to update the parameters.
