UUID v7 Generator API
Generate UUID v7 identifiers that encode timestamps for chronological sorting.
What is UUID v7?
UUID v7 encodes the current Unix timestamp in the first 48 bits, making values sortable by creation time. This is the preferred choice for database primary keys as it reduces index fragmentation.
How to Use
Call GET /api/v1/uuid-v7?count=5. Returns time-sortable UUID v7 identifiers with generation timestamp.
