Common questions about OpenAI API Key Validator, security, supported formats, and performance.

Q:Is it safe to test my key here?

Yes. SopKit performs the check entirely in the browser when possible. Your key is not logged or stored on any server.

Q:What permissions do I need?

Ensure your key has basic read access active so the test request can check the validation endpoints.
