UUID Generator API — Generate Random UUID v4 Identifiers
Generate random UUID v4 (Universally Unique Identifier) strings. Generate single or batch UUIDs for distributed systems. Free API.
What is UUID Generation?
UUID (Universally Unique Identifier) generation creates standardized 128-bit identifiers in the standard 8-4-4-4-12 hexadecimal format (e.g., 550e8400-e29b-41d4-a716-446655440000). The API generates UUID v4 (random) using cryptographically strong random number generation. Supports generating multiple UUIDs at once (up to 100) for batch operations.
How to Use It
Call GET /api/v1/uuid?count=5. Returns { count: number, uuids: string[], version: string }.
