Generations (v1)

Create

Create a new image generation using a model.

const generation = await everart.v1.generations.create(
  '5000',  // Model ID
  'A beautiful landscape',  // Prompt
  'txt2img',  // Generation type
  { 
    imageCount: 1,  // Number of images to generate
    height: 512,    // Optional: Image height
    width: 512,     // Optional: Image width
    webhookUrl: 'https://your-webhook.com'  // Optional: Webhook URL for status updates
  }
);

Fetch

Fetch a specific generation by ID.

const generation = await everart.v1.generations.fetch('generation_id');

Fetch With Polling

Fetch a generation and wait until it's complete.

const generation = await everart.v1.generations.fetchWithPolling('generation_id');

Images (v1)

Upload

Get upload URLs for images.

const uploads = await everart.v1.images.uploads([
  {
    filename: 'image1.jpg',
    content_type: 'image/jpeg'
  },
  {
    filename: 'image2.png',
    content_type: 'image/png'
  }
]);

Supported content types:

• image/jpeg
• image/png
• image/webp
• image/heic
• image/heif

Models (v1)

Create

Create a new fine-tuned model.

// Using URLs
const model = await everart.v1.models.create(
  'My Custom Model',  // Model name
  'OBJECT',          // Model subject type
  [
    { type: 'url', value: 'https://example.com/image1.jpg' },
    { type: 'url', value: 'https://example.com/image2.jpg' },
    // ... more training images (minimum 5)
  ],
  {
    webhookUrl: 'https://your-webhook.com'  // Optional: Webhook URL for training updates
  }
);

// Using local files
const model = await everart.v1.models.create(
  'My Custom Model',  // Model name
  'OBJECT',          // Model subject type
  [
    { type: 'file', path: '/path/to/image1.jpg' },
    { type: 'file', path: '/path/to/image2.jpg' },
    // ... more training images (minimum 5)
  ],
  {
    webhookUrl: 'https://your-webhook.com'  // Optional: Webhook URL for training updates
  }
);

The images parameter accepts an array of image inputs that can be either URLs or local files:

type URLImageInput = { type: 'url'; value: string };
type FileImageInput = { type: 'file'; path: string };
type ImageInput = URLImageInput | FileImageInput;

Supported file types:

JPEG (.jpg, .jpeg) PNG (.png) WebP (.webp) HEIC (.heic) HEIF (.heif)

Fetch

Fetch a specific model by ID.

const model = await everart.v1.models.fetch('model_id');

Fetch Many

Fetch multiple models with optional filtering.

const { models, hasMore } = await everart.v1.models.fetchMany({
  limit: 10,           // Optional: Number of models to fetch
  beforeId: 'id',      // Optional: Fetch models before this ID
  search: 'keyword',   // Optional: Search models by name
  status: 'READY'      // Optional: Filter by status
});

Public Models

EverArt provides access to several public models that you can use for generation:

| Model ID | Name | |----------|------| | 5000 | FLUX1.1 [pro] | | 9000 | FLUX1.1 [pro] (ultra) | | 6000 | SD 3.5 Large | | 7000 | Recraft V3 - Realistic | | 8000 | Recraft V3 - Vector |

Error Handling

The SDK throws typed errors for different scenarios:

type EverArtErrorName =
  | 'EverArtInvalidRequestError'    // 400: Invalid request parameters
  | 'EverArtUnauthorizedError'      // 401: Invalid API key
  | 'EverArtForbiddenError'         // 403: General forbidden access
  | 'EverArtContentModerationError' // 403: Content violates policies
  | 'EverArtRecordNotFoundError'    // 404: Resource not found
  | 'EverArtUnknownError';          // Other errors
