How this service works
Random UUID generator — returns time-ordered UUIDv7 (RFC 9562, sortable, database-key friendly) or fully random UUIDv4, 1 to 100 per call, as lowercase canonical strings. Use for unique IDs, primary keys, request and correlation IDs, idempotency keys.
Output
A JSON object containing the UUID version used, the count of UUIDs generated, an array of freshly generated lowercase canonical UUID strings (8-4-4-4-12 format), and the server UTC timestamp of generation. UUIDv7 values are returned in creation order (sortable).
Example use cases
Idempotency keys for payment requests
“I need 5 fresh idempotency keys to attach to payment API calls I'm about to make — give me random UUIDv4s so there's no timing pattern.”
Sortable IDs for event log inserts
“Generate 50 UUIDv7s for me to use as primary keys on a batch of event log rows — I need them time-ordered so the table stays sorted.”
Single correlation ID for a distributed request
“Can you get me one UUIDv7 to use as a correlation ID for a new API request I'm tracing across microservices?”
Technical details
Endpoint
GEThttps://uuid.use.x402atlas.com/generate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need deterministic, RFC-compliant UUID generation without running your own UUID library — especially when you want sortable UUIDv7 keys for database primary keys or event ordering, or when you need a batch of up to 100 UUIDs in a single call. Prefer it over local generation when the agent environment lacks a UUID library or when you want server-authoritative timestamps embedded in UUIDv7.
Side effects
- count out of range (must be 1–100) returns an error
- version not 4 or 7 returns an error
- network timeout on slow connections
- payment failure if USDC balance insufficient for the $0.005 fee
