Quickstart

Authentication

All requests require an API key:

Authorization: Bearer YOUR_API_KEY

After registering and signing in on the Aeolus site, create a Data API key in the console:

• New users: Register
• Existing accounts: Log in

The key plaintext is shown only once at creation—save it immediately. Invalid or revoked keys return 401 UNAUTHORIZED. See Authentication.
