Quick Start

const { Apiframe } = require('@apiframe-ai/sdk');

const client = new Apiframe({
  apiKey: 'your_api_key_here'
});

async function generateImage() {
  // Create an image generation task
  const task = await client.midjourney.imagine({
    prompt: 'a serene mountain landscape at sunset, photorealistic',
    aspect_ratio: '16:9'
  });

  console.log('Task created:', task.id);

  // Wait for completion with progress updates
  const result = await client.tasks.waitFor(task.id, {
    onProgress: (p) => console.log('Progress:', p)
  });

  console.log('Images ready:', result.image_urls); // imagine returns 4 images
}

generateImage();

TypeScript Support

The SDK is written in TypeScript and includes type definitions:

import { Apiframe, MidjourneyImagineParams, TaskResponse } from '@apiframe-ai/sdk';

const client = new Apiframe({
  apiKey: 'your_api_key_here'
});

const params: MidjourneyImagineParams = {
  prompt: 'a beautiful sunset',
  aspect_ratio: '16:9'
};

const task: TaskResponse = await client.midjourney.imagine(params);
