Install the SDK

The SDK targets Node 20+ and ships with TypeScript types.

npm
npm install @picsart/ai-sdk

Authenticate

Create a client once with your API key — it's sent as a bearer token on every request.

TypeScript
import { createClient } from '@picsart/ai-sdk';

const ai = createClient({
  apiKey: process.env.PICSART_API_KEY, // sent as: Authorization: Bearer <key>
  apiUrl: 'https://api.picsart.com',
});

Run the model

Call the model with its parameters. This example uses the required ones.

TypeScript
import { createClient } from '@picsart/ai-sdk';

const ai = createClient({
  apiKey: process.env.PICSART_API_KEY,
  apiUrl: 'https://api.picsart.com',
});

const result = await ai.generate('eleven-multilingual-sts-v2', {
  audioUrl: "https://cdn.example.com/input.mp3"
});

console.log(result.url); // audio URL

Parameters

5 parameters. Required ones must be supplied; the rest fall back to their defaults. The API takes these same names over HTTP.
