FAQ
What is API Key?
It's a unique key used to authenticate requests to an API. It should be kept secret.
What format should I use?
Hexadecimal and Base64 are the most common. UUID is good for unique IDs. Choose based on your system.
Are the keys secure?
Yes! We use cryptographically secure generation. Keys are generated locally in your browser.
What is the prefix?
Prefixes help identify the key type (e.g. 'sk_' for secret key, 'pk_' for public key).
Are the keys secure for production?
Yes! We use crypto.getRandomValues for cryptographically secure generation. But always use HTTPS and store securely.
