Authentication

Base URL

We enforce HTTPS in every request to improve data security and integrity. The API does not support HTTP. All requests should use the following base URL:

https://api.cros.one

Authentication

Cros uses API keys for authentication. Get yours on our API keys dashboard.

Keep your keys secure! Do not share them or expose them in client-side code. For production requests, securely load your key from an environment variable or other secure storage in your backend server.

All REST API requests should include your API key in a Bearer HTTP header:

headers: {
  'Authorization': `Bearer ${process.env.CROS_API_KEY}`
}

Response Codes

Cros uses standard HTTP codes to indicate the success or failure of your requests.
