ID Generator: UUID v4, UUID v7, ULID, NanoID, Base62, Hex
x402
ID Generator: UUID v4, UUID v7, ULID, NanoID, Base62, Hex is a paid API for AI agents from agent-data-tools.revmesh2074.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-30).
Generates multiple unique ID formats (UUID v4, UUID v7, ULID, NanoID, base62, hex) in a single call and optionally decodes the timestamp embedded in a ULID or UUID v7.

How this service works
Generate unique IDs of every common kind in one call: UUID v4 (random), UUID v7 and ULID (time-ordered, sort by creation), NanoID (21 URL-safe characters) and random base62 and hex strings, up to 20 of each, from the platform's cryptographic random source; and decode the creation time hidden in a ULID or UUID v7. Use for database keys, request and trace IDs, file names or test data.
Output
Returns a JSON object with arrays of generated IDs for each requested type (uuidV4, uuidV7, ulid, nanoid, base62, hex — each containing up to 20 entries), and optionally a 'decoded' object with the input ID, its kind (ULID or UUID v7), the embedded timestamp as an ISO string, and the raw millisecond value.
Example use cases
Database primary key generation
“I need 10 ULIDs to use as primary keys for a new batch of records I'm inserting — they need to be time-ordered so I can sort by creation time.”
Request trace ID for distributed tracing
“Generate 3 UUID v4s and 3 UUID v7s I can use as trace IDs for my API requests — I want to see both random and time-sortable options.”
Decode ULID creation timestamp
“Can you tell me when this ULID was created? Here it is: 01HPZM3K2NQVW8X5R7J4G6B0F1”

Endpoint
GEThttps://agent-data-tools.revmesh2074.workers.dev/pack/id-toolbox?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need multiple ID formats generated in a single HTTP call from a cryptographic random source, especially when you want time-ordered IDs (ULID or UUID v7) that sort by creation time, or when you need to decode the creation timestamp hidden inside an existing ULID or UUID v7. It is more efficient than calling separate generators for each type.
Side effects
- count out of range (not 1–20) returns an error
- length out of range (not 8–128) returns an error for string types
- invalid ULID or UUID v7 passed to decode returns an error or null decoded field
- network timeout from Cloudflare Workers edge
- malformed query parameters return a 400 error
