API Key Setup

Step 1: Access API Management

warning

Never enable "Withdraw" - Cadenza does not require withdrawal permissions.

Step 4: IP Restrictions (Recommended)

1. Enable IP restriction
2. Add all of Cadenza's IP addresses:

34.80.181.33,34.80.30.227,35.234.57.233,35.185.174.159,34.81.236.114,35.201.166.55

You must add all 6 IP addresses. Cadenza routes requests through multiple outbound IPs, and missing any address will cause intermittent connection failures.
