How this service works
Machine-readable settlement service
Output
Returns a JSON object indicating whether the provided input string conforms to valid UUID format, likely including a boolean validity flag and possibly the UUID version or canonical form.
Example use cases
Database ID pre-insert validation
“Before I insert this record, check if '6ba7b810-9dad-11d1-80b4-00c04fd430c8' is a properly formatted UUID so I don't get a database error.”
API input sanitization check
“A user submitted 'not-a-real-uuid-12345' as their account ID — can you validate whether it's a real UUID format before I try to look them up?”
Verify UUID from external system
“I got this identifier back from a third-party webhook: 'f47ac10b-58cc-4372-a567-0e02b2c3d479' — is it a valid UUID or is the data malformed?”
Technical details
Endpoint
POSThttps://pennyrail.vercel.app/api/p/nano/validation.uuid--validate-uuidWhen to prefer
Use this endpoint when you need a lightweight, pay-per-call UUID format validation without standing up your own validation logic. Suitable for agents that occasionally need to verify identifiers from untrusted sources or external systems. At $0.001 USDC per call, it is cost-effective for low-volume checks where integrating a dedicated validation library is not practical.
Side effects
- Missing 'input' field in request body returns a validation error
- Empty string input may return invalid rather than an error
- Non-string input types may cause a 400 error
- Network or server errors on the Vercel deployment may return 5xx responses
- Malformed request body returns an error response
