## Read-Only API Access

Read-Only API Access is a restricted permission level for API keys that allows the user to query market data, account balances, and order history without the ability to execute trades or withdraw funds. This is a fundamental security practice for third-party analytical tools, tax software, and portfolio trackers.

By limiting the scope of the API key, the risk of a compromised third-party service is effectively neutralized, as the attacker cannot move assets or manipulate the account. For traders, using read-only keys for non-trading purposes is a critical component of maintaining a secure trading setup.

It ensures that the primary trading infrastructure remains isolated from unnecessary external integrations. This principle of least privilege is essential for minimizing systemic risk.
