Automating Visual Content Creation with Screenshot API

Creating visual content for marketing, documentation, and social media can be time-consuming. Our Screenshot API offers a powerful solution to automate this process, saving hours of manual work while ensuring consistent, high-quality visuals.

The Challenge of Visual Content Creation

Content marketers and documentation teams face several challenges:

Keeping product screenshots up-to-date as interfaces change
Creating consistent visuals across multiple platforms
Generating custom images for different social media dimensions
Maintaining visual consistency in documentation

Automating Marketing Visuals

Generate custom social media preview cards that include website screenshots:

javascript

01const sharp = require('sharp');
02const fetch = require('node-fetch');
03
04async function createSocialPreviewCard(websiteUrl, title, description) {
05  // Capture website screenshot
06  const response = await fetch('https://api.screenshotapi.com/capture', {
07    method: 'POST',
08    headers: {
09      'Content-Type': 'application/json',
10      'Authorization': `Bearer ${process.env.SCREENSHOT_API_KEY}`
11    },
12    body: JSON.stringify({
13      url: websiteUrl,
14      width: 1200,
15      height: 630,
16      format: 'png'
17    })
18  });
19  
20  const data = await response.json();
21  
22  // Download the screenshot
23  const imageResponse = await fetch(data.screenshotUrl);
24  const imageBuffer = await imageResponse.buffer();
25  
26  // Create a template with branding
27  const template = await sharp({
28    create: {
29      width: 1200,
30      height: 630,
31      channels: 4,
32      background: { r: 255, g: 255, b: 255, alpha: 1 }
33    }
34  })
35  .composite([
36    {
37      input: imageBuffer,
38      top: 0,
39      left: 0
40    },
41    {
42      input: {
43        text: {
44          text: title,
45          font: 'Arial',
46          fontSize: 48,
47          rgba: true
48        }
49      },
50      top: 480,
51      left: 50
52    },
53    {
54      input: {
55        text: {
56          text: description,
57          font: 'Arial',
58          fontSize: 24,
59          rgba: true
60        }
61      },
62      top: 550,
63      left: 50
64    }
65  ])
66  .toBuffer();
67  
68  return template;
69}

Product Feature Highlights

Automatically generate feature highlight images for product marketing:

javascript

01async function createFeatureHighlight(url, selector, highlightText) {
02  // Capture screenshot with specific element highlighted
03  const response = await fetch('https://api.screenshotapi.com/capture', {
04    method: 'POST',
05    headers: {
06      'Content-Type': 'application/json',
07      'Authorization': `Bearer ${process.env.SCREENSHOT_API_KEY}`
08    },
09    body: JSON.stringify({
10      url,
11      selector, // CSS selector for the feature to highlight
12      highlight: true,
13      highlightColor: 'rgba(255, 0, 0, 0.3)',
14      format: 'png'
15    })
16  });
17  
18  // Process and add text overlay
19  // ...
20}

Automating Documentation Visuals

API Documentation Examples

Keep your API documentation visually current with automated examples:

javascript

01async function generateApiExampleImage(apiEndpoint, requestBody, responseExample) {
02  // Create a temporary HTML page showing the API request and response
03  const htmlContent = `
04    <!DOCTYPE html>

26    </body>
27    </html>
28  `;
29  
30  // Save HTML to a temporary file or use a service like GitHub Gist
31  
32  // Capture screenshot of the HTML
33  const response = await fetch('https://api.screenshotapi.com/capture', {
34    method: 'POST',
35    headers: {

Integration with Content Management Systems

For maximum efficiency, integrate these automated visual generators with your CMS:

javascript

01// Example WordPress integration using the REST API
02const WordPress = require('wordpress');
03const client = WordPress.createClient({
04  url: 'https://your-wordpress-site.com',
05  username: process.env.WP_USERNAME,
06  password: process.env.WP_PASSWORD
07});
08
09async function updateProductScreenshots() {
10  // Get all product pages
11  const products = await client.getPosts({
12    type: 'product',
13    status: 'publish'
14  });
15  
16  for (const product of products) {
17    // Generate fresh screenshot
18    const screenshot = await captureProductScreenshot(product.link);
19    
20    // Update the featured image
21    await client.uploadMedia({
22      file: screenshot,
23      filename: `product-${product.id}.png`
24    }).then(media => {
25      return client.updatePost(product.id, {
26        featured_media: media.id
27      });
28    });
29  }
30}
