@eternalai-org/sdk

Official TypeScript SDK for EternalAI - Access hundreds of AI models through one unified interface.

Installation

npm install @eternalai-org/sdk
# or

# or
bun add @eternalai-org/sdk

Quick Start

import { EternalAI } from '@eternalai-org/sdk';

const eai = new EternalAI({ apiKey: 'your-api-key' });

Chat Completion

// Streaming
const stream = await eai.chat.send({
  messages: [{ role: 'user', content: 'Hello!' }],
  model: 'openai/gpt-5.1',
  stream: true,
});

for await (const chunk of stream) {
  process.stdout.write(chunk.choices[0].delta.content || '');
}

// Non-streaming
const response = await eai.chat.send({
  messages: [{ role: 'user', content: 'Hello!' }],
  model: 'openai/gpt-5.1',
});
console.log(response.choices[0].message.content);

Image Generation

// Flux - Text-to-Image
const image = await eai.chat.send({
  messages: [{ role: 'user', content: 'A futuristic city at sunset' }],
  model: 'flux/flux-2-pro',
  width: 1920,
  height: 1080,
});
console.log('Image URL:', image.choices[0].message.content);

// Flux - Image-to-Image (with reference)
const edited = await eai.chat.send({
  messages: [{
    role: 'user',
    content: [
      { type: 'text', text: 'Transform into cyberpunk style' },
      { type: 'image_url', image_url: { url: 'https://example.com/photo.jpg' } }
    ]
  }],
  model: 'flux/flux-2-pro',
});

// Flux - Blend 2 images
const blended = await eai.chat.send({
  messages: [{
    role: 'user',
    content: [
      { type: 'text', text: 'Blend subject with style reference' },
      { type: 'image_url', image_url: { url: 'https://example.com/subject.jpg' } },
      { type: 'image_url', image_url: { url: 'https://example.com/style.jpg' } }
    ]
  }],
  model: 'flux/flux-2-pro',
});

// Uncensored AI - Text-to-Image
const uncensored = await eai.chat.send({
  messages: [{ role: 'user', content: [{ type: 'text', text: 'A sunset' }] }],
  model: 'uncensored-ai/uncensored-image',
  type: 'new',                        // 'new' = text-to-image, 'edit' = image-to-image
  lora_config: { 'style-lora': 1 },   // optional LoRA config
});

// Uncensored AI - Image-to-Image
const edited = await eai.chat.send({
  messages: [{
    role: 'user',
    content: [
      { type: 'text', text: 'Transform this image' },
      { type: 'image_url', image_url: { url: 'https://example.com/input.jpg', filename: 'input.jpg' } }
    ]
  }],
  model: 'uncensored-ai/uncensored-image',
  type: 'edit',
  image_config: { loras: ['skin', 'lightning'] },
});

Video Generation

// Wan - Image-to-Video (via chat.send - auto polls)
// ⚠️ Note: This can take 5-10 minutes as it waits for video generation to complete.
// For browser apps, consider using wan.generate() + getResult() for manual polling with UI updates.
const wanVideo = await eai.chat.send({
  messages: [{
    role: 'user',
    content: [
      { type: 'text', text: 'Animate this character' },
      { type: 'image_url', image_url: { url: 'https://example.com/image.png' } }
    ]
  }],
  model: 'wan/wan2.5-i2v-preview',
  resolution: '480P',
  duration: 5,
});
console.log('Video URL:', wanVideo.choices[0].message.content);

// Wan - Direct usage (manual polling - recommended for browser)
const task = await eai.wan.generate({
  messages: [{
    role: 'user',
    content: [
      { type: 'text', text: 'Animate this character' },
      { type: 'image_url', image_url: { url: 'https://example.com/image.png' } }
    ]
  }],
  model: 'wan/wan2.5-i2v-preview',
  resolution: '480P',
  duration: 5,
});

// Get task_id and poll manually (good for UI progress updates)
const taskId = task.output?.task_id;
const result = await eai.wan.getResult(taskId);
if (result.output?.task_status === 'SUCCEEDED') {
  console.log('Video URL:', result.output.video_url);
}

// Uncensored AI - Video generation
const uncensoredVideo = await eai.chat.send({
  messages: [{
    role: 'user',
    content: [
      { type: 'text', text: 'Animate this image' },
      { type: 'image_url', image_url: { url: 'https://example.com/image.jpg' } }
    ]
  }],
  model: 'uncensored-ai/uncensored-video',
  type: 'edit',
  is_magic_prompt: true,
  duration: 5,
  audio: true,
  video_config: { loras: ['flip', 'nsfw'] },
});

AI Search

const search = await eai.chat.send({
  messages: [{ role: 'user', content: 'Latest AI news 2024' }],
  model: 'tavily/search',
});
console.log(search.choices[0].message.content);

Advanced Usage

Flux - Manual Polling (Recommended for Browser)

// Step 1: Start generation - returns immediately with polling_url
const task = await eai.flux.generate({
  messages: [{ role: 'user', content: 'A mountain landscape' }],
  model: 'flux/flux-2-pro',
  width: 1024,
  height: 1024,
  safety_tolerance: 2,
});
console.log('Task started:', task.polling_url);

// Step 2: Poll for result
const result = await eai.flux.pollResult(task.polling_url, {
  interval: 3000,
  maxAttempts: 60,
  onStatusUpdate: (status, attempt) => console.log(`[${attempt}] ${status}`),
});
console.log('Image URL:', result.result?.sample);

// Or check status manually
const status = await eai.flux.getResult(task.polling_url);
if (status.status === 'Ready') {
  console.log('Image URL:', status.result?.sample);
}

Wan - Manual Polling (Recommended for Browser)

// Step 1: Start generation - returns immediately with task_id
const task = await eai.wan.generate(
  {
    messages: [{
      role: 'user',
      content: [
        { type: 'text', text: 'Animate this character...' },
        { type: 'image_url', image_url: { url: 'https://...' } }
      ]
    }],
    model: 'wan/wan2.5-i2v-preview',
    resolution: '480P',
    duration: 5,
  }
);
console.log('Task started:', task.output?.task_id);

// Step 2a: Poll manually (good for custom UI updates)
const taskId = task.output?.task_id;
let result = await eai.wan.getResult(taskId);
while (result.output?.task_status === 'RUNNING' || result.output?.task_status === 'PENDING') {
  await new Promise(r => setTimeout(r, 5000)); // wait 5s
  result = await eai.wan.getResult(taskId);
  console.log('Status:', result.output?.task_status);
}
console.log('Video URL:', result.output?.video_url);

// Step 2b: Or use pollResult for auto-polling with callbacks
const finalResult = await eai.wan.pollResult(taskId, {
  interval: 5000,
  maxAttempts: 120,
  onStatusUpdate: (status, attempt) => console.log(`[${attempt}] ${status}`),
});
console.log('Video URL:', finalResult.output?.video_url);

Uncensored AI - Manual Polling (Recommended for Browser)

// Step 1: Start generation - returns immediately with request_id
const task = await eai.uncensoredAI.generate({
  messages: [{ role: 'user', content: [{ type: 'text', text: 'A sunset' }] }],
  model: 'uncensored-ai/uncensored-image',
  type: 'new',
  lora_config: { 'style-lora': 1 },
});
console.log('Task started:', task.request_id);

// Step 2: Poll for result
const result = await eai.uncensoredAI.pollResult(task.request_id, 'uncensored-image', {
  interval: 3000,
  maxAttempts: 60,
  onStatusUpdate: (status, attempt) => console.log(`[${attempt}] ${status}`),
});
console.log('URL:', result.result_url);

// Or check status manually
const status = await eai.uncensoredAI.getResult(task.request_id, 'uncensored-image');
if (status.status === 'success') {
  console.log('URL:', status.result_url);
}
