Portkey SDK Integration with Nscale

Portkey provides a consistent API to interact with models from various providers. To integrate Nscale with Portkey:

1. Install the Portkey SDK

NodeJS

npm install --save portkey-ai

Python

pip install portkey-ai

2. Initialize Portkey with the Virtual Key

To use Nscale with Virtual Key, get your API key from here. Then add it to Portkey to create the virtual key.

NodeJS SDK

import Portkey from 'portkey-ai'

const portkey = new Portkey({
  apiKey: "PORTKEY_API_KEY", // defaults to process.env["PORTKEY_API_KEY"]
  provider:"@PROVIDER" // Your Nscale Virtual Key
})

Python SDK

from portkey_ai import Portkey

portkey = Portkey(
  api_key="PORTKEY_API_KEY",  # Replace with your Portkey API key
  provider="@NSCALE_PROVIDER"
)

3. Invoke Chat Completions

NodeJS SDK

const chatCompletion = await portkey.chat.completions.create({
  messages: [{ role: 'user', content: 'Say this is a test' }],
  model: 'meta-llama/Llama-4-Scout-17B-16E-Instruct',
});

console.log(chatCompletion.choices);

Python SDK

completion = portkey.chat.completions.create(
  messages= [{ "role": 'user', "content": 'Say this is a test' }],
  model= 'meta-llama/Llama-4-Scout-17B-16E-Instruct'
)

print(completion)

4. Invoke Image Generation

NodeJS SDK

const response = await portkey.images.generations.create({
  prompt: "A beautiful sunset over mountains",
  model: "stabilityai/stable-diffusion-xl-base-1.0",
  n: 1,
  size: "1024x1024"
});

console.log(response.data[0].url);

Python SDK

response = portkey.images.generate(
  prompt="A beautiful sunset over mountains",
  model="stabilityai/stable-diffusion-xl-base-1.0",
  n=1,
  size="1024x1024"
)

print(response.data[0].url)
