+# Vanilla HTML
+
+For static sites or any project without a JS framework. The form posts directly to the Worker, no client-side JavaScript required for the integration itself.
+
+```html
+<!doctype html>
+<html>
+	<head>
+		<script
+			src="https://challenges.cloudflare.com/turnstile/v0/api.js"
+			async
+			defer
+		></script>
+	</head>
+	<body>
+		<form action="https://YOUR_WORKER_URL/" method="POST">
+			<input name="email" type="email" required />
+			<div
+				class="cf-turnstile"
+				data-sitekey="YOUR_SITEKEY"
+				data-action="turnstile-spin-v1"
+			></div>
+			<button type="submit">Subscribe</button>
+		</form>
+	</body>
+</html>
+```
+
+When the form is submitted, the browser includes `cf-turnstile-response` automatically. The Worker reads it (alias for `token`) and responds with siteverify JSON.
+
+## Where to put the snippet
+
+- Single-page site: in the `<body>` of `index.html`, wherever the form lives.
+- Multi-page site: in each page that has a form. The script tag in `<head>` can live in a shared layout.
+
+## Substitutions
+
+| Placeholder        | Replace with                                            |
+| ------------------ | ------------------------------------------------------- |
+| `YOUR_WORKER_URL`  | The deployed Worker URL from Step 5                     |
+| `YOUR_SITEKEY`     | The widget site key from Step 4                         |
+
+## Variant: AJAX submit instead of form action
+
+If the form is submitted via `fetch` instead of a native form post, the snippet still works. The widget div populates a hidden `cf-turnstile-response` input that you can read from `new FormData(form)`.
+
+```html
+<script>
+	document.querySelector("form").addEventListener("submit", async (e) => {
+		e.preventDefault();
+		const data = new FormData(e.target);
+		const res = await fetch("https://YOUR_WORKER_URL/", {
+			method: "POST",
+			body: data,
+		});
+		const json = await res.json();
+		if (json.success) {
+			// proceed
+		}
+	});
+</script>
+```
