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.green-salad-4efd.toolsminati.workers.dev',
});

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.green-salad-4efd.toolsminati.workers.dev',
});

const result = await ai.generate('ltx-v2.3-reframe', {
  videoUrl: "https://cdn.example.com/input.mp4",
  resolution: "1080p",
  aspectRatio: "16:9"
});

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

Parameters

3 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
`videoUrl` Source Video	`file (video)`	yes	`—`	—
`resolution`	`enum`	no	`1080p`	720p, 1080p
`aspectRatio`	`enum`	no	`16:9`	16:9, 9:16, 1:1, 4:5, 5:4

Output

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