Overview

Alongside the unified model APIs, we expose compatibility APIs that take each vendor's original parameters exactly as the vendor defines them — nothing renamed, nothing reshaped on the way through.

That makes them the shortest path onto Picsart if you already work with the vendor directly: the request bodies you've already written keep working as they are. You keep their parameter names and defaults, and you get the vendor's full parameter set rather than the subset that is shared across every model.

The cost is that a request is written for one vendor — switching models later means rewriting it, and results come back in the vendor's own shape. When you'd rather write once and change models freely, use the unified API.

Make a request

Call the workflow with ai.apis.run() in TypeScript, or hit /workflows/{workflow}/execute directly — params is passed through untouched either way.

These endpoints are addressed by workflow name rather than model id: the one in this model's header, since one model runs as one workflow. Authentication is unchanged — your Picsart API key as a bearer token (see Authentication).

ts
import { createClient, ApiRunMode } from '@picsart/ai-sdk';

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

// Calls the 'flux/v1/video' workflow directly — params are sent as-is.
const { result, usage } = await ai.apis.run('flux/v1/video', {
  prompt: "A serene mountain lake at golden hour, ultra detailed"
}, {
  mode: ApiRunMode.SYNC,
});

console.log(result); // workflow-specific output
console.log(usage?.credits); // credits charged

Async (submit & poll)

This model can run longer than the sync limit (~20s). In TypeScript, ai.apis.run(…, { mode: ApiRunMode.ASYNC }) polls for you; over HTTP, submit and poll yourself.

ts
import { createClient, ApiRunMode } from '@picsart/ai-sdk';

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

// mode: ASYNC submits the job and polls under the hood — you just await.
const { result } = await ai.apis.run('flux/v1/video', {
  prompt: "A serene mountain lake at golden hour, ultra detailed"
}, {
  mode: ApiRunMode.ASYNC,
});

console.log(result);

Parameters

11 parameters, sent inside params. These are the vendor's own names, so they line up one-for-one with the vendor's documentation. Required ones must be supplied; the rest fall back to their defaults.

ParameterTypeRequiredDefaultDetails
prompt
Text prompt in plain language describing the video.
stringyes
keyframes
1 to 10 images (public URL or base64) to animate (image-to-video). Providing these selects i2v mode.
string[]no
startVideo
One mp4 (URL or base64, ≤ 50 MB, ≤ 15s) to continue from its final frames (video-to-video). Selects v2v mode.
stringno
aspectRatio
Aspect ratio. `auto` picks one from the prompt and inputs.
stringnoauto
auto21:92:116:94:31:13:49:16
resolution
Output resolution: `hd` (720p) or `fhd` (1080p).
stringnohd
hdfhd
duration
Clip length in seconds (whole number 5–20) or "auto" (model fits length to content).
integer | stringnoauto
generateAudio
Whether to generate synchronized audio (ambient, speech, effects).
booleannotrue
safetyTolerance
Moderation level (0 = strict, 4 = permissive).
numberno2
0–4
webhookUrl
URL the vendor POSTs the completed result to, as an alternative to polling.
stringno
draft
Produce a fast low-step preview. Its own quality tier for pricing and incompatible with `fhd` resolution (use `hd`). The response also returns a draftCache bundle (the vendor can replay it at full quality; this worker does not expose that replay).
booleanno
options
Options controlling safety checks and Picsart Drive integration
objectno
safety_checks
Safety check settings
objectno
enabled
Whether to run content moderation. Defaults to true.
booleanno
drive
Save result to Picsart Drive
objectno
name
File name in Picsart Drive
stringyes
attributes
Custom attributes to attach to the file
objectno
folder
Target folder in Picsart Drive
objectno

Response

Over HTTP the output arrives inside a status envelope, at response.result. ai.apis.run() unwraps that envelope for you and resolves to { result, usage } instead. Either way the resultitself is the vendor's own shape.
