+    <h1>Generate OG Images & Social Media Previews with a Screenshot API</h1>
+
+    <p>When you share a link on Twitter, LinkedIn, or Slack, the platform fetches an Open Graph image to display as a preview card. Static OG images are fine for homepages — but what about blog posts, user profiles, or product pages that need <strong>unique, dynamic preview images</strong>?</p>
+
+    <p>SnapAPI lets you render any HTML page as a PNG image via a simple API call. Build an HTML template with your title, author, and branding, host it on a URL, and let SnapAPI screenshot it into a pixel-perfect OG image.</p>
+
+    <h2>How It Works</h2>
+
+    <p>The workflow is straightforward:</p>
+    <ol>
+      <li><strong>Create an HTML template</strong> — Design your OG card layout (1200×630px) with CSS. Use query parameters for dynamic content.</li>
+      <li><strong>Call SnapAPI</strong> — Pass the template URL to the screenshot endpoint. SnapAPI renders it in a real Chromium browser.</li>
+      <li><strong>Serve the image</strong> — Use the returned PNG as your <code>og:image</code> meta tag, or cache it on your CDN.</li>
+    </ol>
+
+    <h2>Code Example</h2>
+
+    <h3>Screenshot an OG Template</h3>
+    <div class="code-window">
+      <div class="code-titlebar"><span class="code-dot"></span><span class="code-dot"></span><span class="code-dot"></span><span>Node.js</span></div>
+      <div class="code-body"><pre><span class="kw">const</span> response = <span class="kw">await</span> <span class="fn">fetch</span>(<span class="str">'https://snapapi.eu/v1/screenshot'</span>, {
+  method: <span class="str">'POST'</span>,
+  headers: {
+    <span class="str">'Content-Type'</span>: <span class="str">'application/json'</span>,
+    <span class="str">'X-API-Key'</span>: process.env.<span class="prop">SNAPAPI_KEY</span>
+  },
+  body: JSON.stringify({
+    url: <span class="str">'https://yoursite.com/og-template?title=My+Post&amp;author=Jane'</span>,
+    width: <span class="prop">1200</span>,
+    height: <span class="prop">630</span>,
+    format: <span class="str">'png'</span>
+  })
+});
+
+<span class="kw">const</span> imageBuffer = <span class="kw">await</span> response.<span class="fn">arrayBuffer</span>();
+<span class="cmt">// Upload to S3, serve from CDN, or return directly</span></pre></div>
+    </div>
+
+    <h3>Dynamic Meta Tags</h3>
+    <p>Point your <code>og:image</code> to a serverless function that calls SnapAPI on-the-fly:</p>
+
+    <div class="code-window">
+      <div class="code-titlebar"><span class="code-dot"></span><span class="code-dot"></span><span class="code-dot"></span><span>HTML</span></div>
+      <div class="code-body"><pre><span class="cmt">&lt;!-- In your page's &lt;head&gt; --&gt;</span>
+&lt;meta property=<span class="str">"og:image"</span>
+      content=<span class="str">"https://yoursite.com/api/og?title=My+Blog+Post"</span> /&gt;
+&lt;meta property=<span class="str">"og:image:width"</span> content=<span class="str">"1200"</span> /&gt;
+&lt;meta property=<span class="str">"og:image:height"</span> content=<span class="str">"630"</span> /&gt;</pre></div>
+    </div>
+
+    <h2>Why Use SnapAPI for OG Images?</h2>
+    <ul>
+      <li><strong>Real browser rendering</strong> — Full CSS support, custom fonts, gradients, SVGs. No template language limitations.</li>
+      <li><strong>EU-hosted, GDPR compliant</strong> — All rendering happens on servers in Germany. No data leaves the EU.</li>
+      <li><strong>Fast</strong> — Typical render times under 2 seconds. Cache the result and serve instantly.</li>
+      <li><strong>Simple API</strong> — One POST request, one image back. No SDKs required.</li>
