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('heygen-video-avatar', {
  videoId: "",
  resolution: "720p",
  aspectRatio: "16:9",
  voiceId: "",
  prompt: "A serene mountain lake at golden hour, ultra detailed"
});

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

Parameters

5 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
`videoId` Avatar	`catalog`	yes		options from heygen/v1/catalog/avatars
`resolution`	`enum`	no	`720p`	4k, 1080p, 720p
`aspectRatio`	`enum`	no	`16:9`	16:9, 9:16
`voiceId` Voice	`catalog`	yes		options from heygen/v1/catalog/voices
`prompt` Prompt	`text`	yes	`—`	max 5000 chars · e.g. "Write the script your avatar will speak (at least 20 characters)..."

Output

generate() resolves once the job completes. A video URL.
