    Getting Started with Flixly API

    Step 1: Sign Up and Get Your API Key

    Head to flixly.ai and create a free account. Once logged in:

  • Navigate to the API Dashboard.

  • Generate your API key – it's your golden ticket.

  • Store it securely (use environment variables, not hardcode it).
  • Pro Tip: API keys are scoped to your plan. Upgrade for higher limits and priority access.

    Step 2: Install SDK or Use Raw HTTP

    Flixly provides official SDKs for easy integration.

    Python Setup:

    pip install flixly-sdk

    JavaScript/Node.js:

    npm install flixly-sdk

    For raw HTTP, use tools like curl, Postman, or your favorite HTTP client.

    Making Your First API Call

    Let's generate an image! The core endpoint is POST /v1/images/generations.

    Basic Parameters

    Key parameters for Flixly API image generation:

    | Parameter | Type | Description | Default |
    |-----------|------|-------------|---------|
    | prompt | string | Text description | Required |
    | width | int | Image width (e.g., 1024) | 1024 |
    | height | int | Image height | 1024 |
    | n | int | Number of images | 1 |
    | model | string | 'flixly-v1' or 'flixly-pro' | 'flixly-v1' |
    | quality | string | 'standard' or 'hd' | 'standard' |

    Python Example

    import os
    from flixly import Flixly

    client = Flixly(api_key=os.getenv('FLIXLY_API_KEY'))

    response = client.images.generate(
    prompt="A futuristic cityscape at sunset, cyberpunk style",
    width=1024,
    height=1024,
    n=1,
    model='flixly-pro'
    )

    image_url = response.data[0].url
    print(f"Generated image: {image_url}")

    This code sends a request and returns a URL to your new image. Download it with requests.get(image_url).

    JavaScript Example

    const Flixly = require('flixly-sdk');

    const client = new Flixly({ apiKey: process.env.FLIXLY_API_KEY });

    async function generateImage() {
    const response = await client.images.generate({
    prompt: 'A majestic dragon flying over mountains',
    width: 1024,
    height: 1024,
    n: 1
    });

    console.log('Image URL:', response.data[0].url);
    }

    generateImage();

    Raw cURL Example

    curl https://api.flixly.ai/v1/images/generations \
    -H "Authorization: Bearer YOUR_API_KEY" \
    -H "Content-Type: application/json" \
    -d '{
    "prompt": "Serene beach at dawn",
    "width": 1024,
    "height": 1024,
    "n": 1
    }'

    Expect a JSON response like:

    {
    "data": [{"url": "https://flixly.ai/generated/abc123.png"}]
    }

    Advanced Flixly API Features

    Fine-Tuning Prompts for Better Results

    Crafting the perfect prompt is an art. Use this AI image API tutorial structure:

  • Subject + Action + Environment + Style + Details

  • Example: "A wise old wizard casting a spell in an enchanted forest, fantasy art style, highly detailed, cinematic lighting."
  • Tips:

  • Be specific: "Red sports car" vs. "Sleek red Ferrari 488 on a rainy Tokyo street at night."

  • Use negative prompts: Add negative_prompt to exclude elements like "blurry, low quality."

  • Experiment with styles: "oil painting," "photorealistic," "pixel art."
  • Batch Generation and Upscaling

    Generate multiple variations:

    response = client.images.generate(prompt="Abstract art", n=4)

    For HD, use the upscale endpoint:

    upscaled = client.images.upscale(image_url, scale=2)

    Image-to-Image and Editing

    Transform existing images:

  • Endpoint: POST /v1/images/edit

  • Parameters: image (base64 or URL), prompt, mask (optional).
  • Example: Turn a sketch into a full-color illustration.

    Error Handling and Best Practices

    Common errors:

  • 401 Unauthorized: Invalid API key.

  • 429 Rate Limit: Too many requests – implement retries with exponential backoff.

  • 400 Bad Request: Invalid params – validate inputs.
  • Best Practices:

  • Rate Limiting: Check X-RateLimit-Remaining headers.

  • Async Processing: Use webhooks for long jobs.

  • Caching: Store generated URLs to avoid duplicates.

  • Security: Never expose API keys client-side.
  • Integrate with Flixly's AI Video Generator for dynamic content pipelines.

    Real-World Use Cases
