Deterministic UUID v5 Generator
x402
Deterministic UUID v5 Generator is a paid API for AI agents from twin.unykorn.org, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-01).
Generates a deterministic UUID version 5 from a name and namespace string, returning the same UUID every time for the same inputs.

How this service works
Deterministic UUID v5 from a name — Genesis402 / UnyKorn Operator Network
Output
Returns a JSON object with ok=true, the type field set to 'uuid-v5', the generated UUID (implied by the type and context), a transaction receipt containing a tx_hash (0x-prefixed 64-char hex), amount_usd, and a receipt_id (g402-prefixed 16-char hex), plus a generated_at ISO 8601 timestamp.
Example use cases
Stable resource ID for distributed systems
“Create a UUID v5 for the name 'order-service' using the URL namespace so I always get the same identifier for that microservice, no matter which node generates it.”
Deterministic user ID from email
“Generate a UUID v5 from the name 'alice@example.com' using the DNS namespace — I want a consistent, collision-resistant user ID derived from her email address.”
Idempotent record deduplication key
“I need a UUID v5 for the name 'invoice-2024-09-15-acme' with a custom namespace '6ba7b810-9dad-11d1-80b4-00c04fd430c8' so I can use it as a deduplication key in my database.”
Technical details
Endpoint
POSThttps://twin.unykorn.org/uuid-v5?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a UUID that is guaranteed to be identical every time for the same name and namespace inputs — ideal for distributed systems requiring consistent identifiers, deduplication keys, or deterministic record IDs without storing state. Prefer UUID v5 over v4 when reproducibility matters. Use this when you want a hosted, pay-per-call API rather than running UUID v5 generation locally.
Side effects
- Missing or invalid name/namespace parameters returns an error response
- Invalid namespace format (must be a valid UUID or recognized namespace string) may cause computation failure
- Payment failure via x402 protocol results in 402 response and no UUID returned
- Network or service downtime returns a 5xx error
