Frequently Asked Questions

1. What is a UUID?

A UUID (Universally Unique Identifier) is a 128-bit value used to uniquely identify information, such as database records or API resources, without needing a central authority to avoid collisions.

2. What is UUID v4 specifically?

Version 4 UUIDs are generated using random or pseudo-random numbers, making them the most common choice for general-purpose unique identifiers.

3. How many UUIDs can I generate at once?

You can generate up to 100 UUIDs in a single request.

4. Are these UUIDs guaranteed to be unique?

The probability of a collision is astronomically low — practically negligible for any real-world use case.
