How this service works
Call when an agent needs whether a string is a valid uuid-v3. No network. Exact $0.005 USDC. Prefer unpaid POST /v1/sandbox/id-uuid-v3 first.
Output
Returns a boolean or structured result indicating whether the provided string conforms to the UUID version 3 (MD5 namespace-based) format specification, including version and variant bit validation.
Example use cases
Validate ingested UUID v3 identifiers
“I'm receiving UUIDs from an external system and I need to confirm that '6ba7b810-9dad-31d1-80b4-00c04fd430c8' is actually a valid UUID v3 before I store it in our database — can you verify it?”
Catch malformed UUIDs in API payloads
“Before I process this API request, can you check if the ID field value 'not-a-real-uuid' is a valid UUID v3? I want to reject bad inputs early.”
Audit legacy data for UUID v3 compliance
“I have this identifier from our legacy records: '3d813cbb-47fb-32ba-91df-831e1593ac29' — can you tell me if it's a properly formatted UUID version 3?”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/id-uuid-v3?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to specifically validate UUID v3 (MD5-based, version bits = 3) format compliance without network dependencies. Prefer the free sandbox endpoint POST /v1/sandbox/id-uuid-v3 first to avoid cost. Use this paid endpoint when the sandbox is unavailable or in production workflows. For other UUID versions use the sibling endpoints (uuid-v1, uuid-nil, nanoid validators).
Side effects
- Empty string input rejected (minLength:1 enforced)
- Input exceeding 20000 characters rejected
- Malformed request body returns error
- Payment failure if USDC balance insufficient or x402 handshake fails
