How this service works
Machine-readable settlement service
Output
Returns a UUID version 7 string — a 128-bit, time-ordered unique identifier encoded in standard UUID hyphenated format (e.g. 018f1234-abcd-7000-8000-000000000001). The response is a JSON object containing the generated UUID value.
Example use cases
Database primary key generation
“I need a new UUID v7 to use as the primary key for a record I'm about to insert into my Postgres table — can you generate one?”
Distributed event tracking ID
“Generate a time-ordered UUID v7 I can attach to this new event in my event-sourcing pipeline so records stay naturally sortable.”
Idempotency key for API request
“I need a fresh UUIDv7 to use as an idempotency key before I send off a payment request — can you get me one?”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/utility.uuid-generate--uuid-v7When to prefer
Choose this endpoint when you need a time-sortable, monotonically increasing unique identifier (UUID v7) rather than a random UUID v4. Prefer it in distributed systems where records must be sortable by creation time using the ID alone, or when inserting into databases that benefit from sequential key ordering. Use over UUID v4 generators when chronological ordering of IDs matters for performance or auditing.
Side effects
- Payment failure: insufficient USDC balance or x402 payment not accepted, resulting in 402 Payment Required
- Empty or malformed input object causes validation error
- Service unavailability on Vercel hosting returns 5xx
- Rate limiting if too many calls are made in quick succession
