Exchange APIs let software request market data or manage account actions. An API key is a credential that can carry permissions, so it should be limited to the exact tasks and systems that need it.
Grant only the permissions an application needs
A read-only market-data tool does not need trading or withdrawal access. Where available, restrict keys by IP address, disable unused scopes, and create separate credentials for separate applications.
Read-only keys reduce account impact
Use read access for analytics and monitoring that do not need to place trades.
Protect, monitor, and rotate credentials
Do not publish secrets in source code, screenshots, browser apps, or shared logs. Store them in a secret manager, monitor account activity, revoke exposed keys quickly, and use the exchange’s current authentication guidance.
Revoke exposed keys immediately
Treat API secrets like passwords and rotate them after any suspected disclosure.
