Mage TypeScript SDK

The official TypeScript client for the Mage API. Use it to generate images, video, and audio with Mage models from your own server code.

Beta. This SDK is at 0.x and may still change between minor versions. The API itself is versioned separately and stays stable within v1.

Install

npm install @mage-space/sdk

You need Node.js 20.19 or later, or any other runtime with fetch. The package is ESM-only; recent Node versions can require() it as well.

Keep your API key on your servers. The API does not send CORS headers, so browsers cannot call it, and anyone who has the key can spend your Gems.

Quick start

Create a key under API → API Keys and set it as MAGE_API_KEY.

import Mage from '@mage-space/sdk';

const mage = new Mage(); // reads MAGE_API_KEY

const request = await mage.run('mango', {
  prompt: 'Editorial portrait in soft daylight, 35mm film look',
  aspect_ratio: '4:5',
});

console.log(request.result.url);

run submits the generation, polls until it finishes, and resolves to the completed request. Results are kept for 30 days, so download anything you want to keep.

Models

Every model's config is typed. The first argument is the architecture id from the endpoint path (mango, cherry, seed_audio, …); model_id selects a variant inside it.

// Video with Cherry 2 Pro, guided by a reference image.
const video = await mage.run('cherry', {
  prompt: 'The camera slowly pushes in as the lights come on',
  model_id: 'cherry-2-pro',
  image: 'https://example.com/reference.png',
  resolution: '720p',
  duration: '5',
});

// Audio with Seed Audio.
const audio = await mage.run('seed_audio', {
  prompt: 'Warm lo-fi beat with vinyl crackle',
  duration: '30',
});

See the model reference for every model's fields, options, and prices. ARCHITECTURES lists the ones this version of the SDK knows, and the MangoConfig, CherryConfig, … types are exported.

A model released after your version of the SDK still works: pass its id as a string, and the config is checked only against the fields every model shares.

Submitting and polling separately

const submitted = await mage.generate('cherry', { prompt: 'Waves at dusk' });
console.log(submitted.request_id, submitted.status); // e.g. "in_progress"

// Later, perhaps in another process:
const final = await mage.requests.wait(submitted.request_id, {
  timeout: 15 * 60_000,
  onUpdate: (request) => console.log(request.status),
});

if (final.status === 'completed') console.log(final.result?.url);

requests.wait polls with the backoff the API recommends: it starts at 2 seconds, multiplies the delay by 1.5 after each read, adds jitter, and caps the delay at 15 seconds. It resolves to the final request whatever its status. run throws MageGenerationError instead when a request fails or is cancelled.

requests.get(id) reads a request's current state once. requests.cancel(id) stops a live request; its Gems are not returned.

Images, video, and audio as inputs

Media fields accept an https URL or a data URL. For files larger than about 3 MB, or files that are not at a public URL, upload them first:

import { readFile } from 'node:fs/promises';

const clip = await mage.uploads.upload(await readFile('clip.mp4'), {
  contentType: 'video/mp4',
});

await mage.run('cherry', {
  prompt: 'Restyle this clip as a watercolor painting',
  videos: [clip.url],
});

Uploaded files expire after 30 days (clip.url_expires_at).

Characters and references

Saved characters and references are used by writing their @handle in the prompt:

await mage.characters.create({
  name: 'Ana',
  handle: 'ana',
  image: 'https://example.com/ana.png',
});

await mage.run('mango', { prompt: '@ana walking through a night market' });

const page = await mage.characters.list({ limit: 50 });
// Pass page.next_cursor as `cursor` to read the next page.

mage.references works the same way for objects, locations, poses, outfits, and audio clips.

Errors

Error	When
MageAPIError	The API answered with an error. It has status, code (such as insufficient_gems or invalid_config), message, and requestId. Handle a code you do not recognise by its status.
MageGenerationError	run finished with a failed or cancelled request. It has code, reason, stage, and request.
MageTimeoutError	wait or run reached your timeout, which also cuts short a status read in progress. The request keeps running; request is the last state read.
MageConnectionError	No response arrived after retrying.
MageError	The base class of all of the above, also thrown for a missing API key.

import { MageAPIError } from '@mage-space/sdk';

try {
  await mage.run('mango', { prompt: 'A lighthouse at night' });
} catch (error) {
  if (error instanceof MageAPIError && error.code === 'insufficient_gems') {
    // Top up and try again.
  }
  throw error;
}
