Price: $0.20 / 1k solves · Speed: ~0.8s

captcha.eu is a GDPR-compliant captcha hosted in Europe. No cookies, no tracking.

Finding the site key

Look in the page HTML for the widget script or div:

<script src="https://www.captcha.eu/sdk.js" data-sitekey="your_public_secret"></script>

Or:

<div class="captcha-eu" data-sitekey="your_public_secret"></div>

The value is called a publicSecret in captcha.eu's documentation.

Request

{
  "type": "CaptchaEuProxyless",
  "site_key": "your_public_secret",
  "site_url": "https://example.com"
}

You can also use public_secret instead of site_key — both are accepted:

{
  "type": "CaptchaEuProxyless",
  "public_secret": "your_public_secret"
}

site_url is optional for captcha.eu.

Response

{
  "success": true,
  "token": {
    "challenge": "abc123...",
    "solutions": [{ "hash": "0000abc...", "nonce": "xyz..." }],
    "expires": "2026-01-01T00:00:00Z"
  },
  "took_ms": 750,
  "cost": 0.0002
}

Submit the token object to the site's captcha.eu verification endpoint.
