Authentication - Endole API

The Endole API uses HTTP authentication to securely authorise requests. Every request sent to the Endole API must include an Authorization header containing your 64-character API key.

Header Format

Authenticate your requests by including your API key in the Authorization header using Bearer authentication. Pass your raw API key directly without any Base64 encoding:

Authorization: Bearer YOUR_API_KEY

Example Request

curl -X GET "https://api.endole.co.uk/company/01234567/financials" \
     -H "Authorization: Bearer 33e5ea84ca6e9ce3f70b13a4e13d9cf9e451411f1f2140d21e8e5531cd37fec"

Never share your API key or expose it in client-side code (like JavaScript in a web browser). Store keys safely in environment variables on your backend server.
