Portkey SDK Client

The Portkey SDK client enables various features of Portkey in an easy to use config-as-code paradigm.

Install the Portkey SDK

Add the Portkey SDK to your application to interact with Portkey's gateway.

npm install --save portkey-ai

Export Portkey API Key

export PORTKEY_API_KEY=""

Basic Client Setup

The basic Portkey SDK client needs 2 required parameters

  1. The Portkey Account's API key to authenticate all your requests

  2. The virtual key of the AI provider you want to use OR The config being used

This is achieved through headers when you're using the REST API.

For example,

import Portkey from 'portkey-ai';

// Construct a client with a virtual key
const portkey = new Portkey({
    apiKey: "PORTKEY_API_KEY",
    virtualKey: "VIRTUAL_KEY"
})

// Construct a client with a config id
const portkey = new Portkey({
    apiKey: "PORTKEY_API_KEY",
    config: "cf-***" // Supports a string config slug or a config object
})

Find more info on what's available through configs here.

Making a Request

You can then use the client to make completion and other calls like this

const chatCompletion = await portkey.chat.completions.create({
    messages: [{ role: 'user', content: 'Say this is a test' }],
    model: 'gpt-3.5-turbo',
});

console.log(chatCompletion.choices);

Passing Trace ID or Metadata

You can choose to override the configuration in individual requests as well and send trace id or metadata along with each request.

const chatCompletion = await portkey.chat.completions.create({
    messages: [{ role: 'user', content: 'Say this is a test' }],
    model: 'gpt-3.5-turbo',
}, {
    traceId: "39e2a60c-b47c-45d8", 
    metadata: {"_user": "432erf6"}
});

console.log(chatCompletion.choices);

Parameters

Following are the parameter keys that you can add while creating the Portkey client.

Keeping in tune with the most popular language conventions, we use:

  • camelCase for Javascript keys

  • snake_case for Python keys

  • hyphenated-keys for the headers
