Overview

Botd is an open-source JavaScript library and API from FingerprintJS that detects whether a web visitor is a bot or a real human browser. It analyzes browser signals in real time and returns a bot detection result that you can verify on your server. It is commonly used to protect login forms, signup flows, and APIs from automated abuse.

Beginner Tip

Include the Botd JavaScript snippet on your page to generate a detection result token, then send that token to your backend and verify it via the API. The client-side library does the heavy lifting — the API just validates the result.

Available Data

The kind of data this API exposes, based on its documentation. We could not call the endpoint to confirm the exact field names.

Example Response

Illustrative shape only — we were not able to call this endpoint (it requires credentials or exposes no public sample URL), so the fields below show the kind of data this API returns rather than a recorded response.

Implementation Example

Calls a real endpoint of this API. Replace any placeholder credentials with your own key.

Request

const url = "https://botd.fpapi.io/api/v1/verify?token=RESULT_TOKEN";
// Replace headers or query params with the values required by this API.
const response = await fetch(url, {
  headers: {
  "X-API-Key": "YOUR_API_KEY"
  }
});
if (!response.ok) throw new Error(`Request failed: ${response.status}`);
const data = await response.json();
console.log(data);

Common Errors & Troubleshooting

Generated guidance based on this API's documentation, not observed by us. Treat it as a starting point and check against the provider's own error reference.

401 Unauthorized The API key is missing or incorrect in the request.

✓ Pass your Botd API key in the Auth-Token header or as a query parameter as documented.

Token already used Botd result tokens are single-use and expire quickly.

✓ Always verify the token immediately after the user action — do not cache or re-use tokens.

CORS error in browser The Botd API endpoint is being called directly from the browser instead of your backend.

✓ Only call the verification API from your server-side code, never from the browser.

Metadata Score Breakdown

Estimated from metadata — endpoint not independently tested

This score is estimated from observable metadata — HTTPS support, authentication model, declared CORS, and documentation reachability — because the API requires authentication or exposes no publicly testable endpoint. The five-signal breakdown is only shown for live-tested APIs.
