How this service works
Machine-readable settlement service
Output
Returns a generated UUID string as a proven unique identifier, wrapped in a JSON response object. The exact shape of the response may vary but will contain the UUID value.
Example use cases
Unique ID for new database record
“I'm inserting a new user record into my database and I need a fresh, collision-resistant UUID to use as its primary key — can you generate one for me?”
Idempotency key for distributed transaction
“I need a new UUID to use as an idempotency key before I submit this payment request, so I can safely retry it without duplicates.”
Unique session token generation
“Generate a UUID I can use as a unique session identifier for a new user login event I'm about to log.”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/utility.uuid-generate--proven-uuidWhen to prefer
Choose this endpoint when you need a lightweight, pay-per-use UUID generation service without setting up your own infrastructure, particularly in agentic or micro-service pipelines that already use x402 payment rails. It is well-suited for low-volume, on-demand unique ID generation where spinning up a dedicated service is overkill.
