SDK API Advanced Usage Pricing

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('async-flash-v1', {
  prompt: "A serene mountain lake at golden hour, ultra detailed"
});

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

Parameters

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

Parameter	Type	Required	Default	Details
`prompt` Prompt	`text`	yes	`—`	—
`voiceId` Voice	`catalog`	no	`cca0e076-b350-4966-b570-4c2fca50b525`	options from async-ai/v1/catalog/voices
