UUID v4 Generator
x402
UUID v4 Generator is a paid API for AI agents from flat-rate-llm.kikoribera03.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-30).
Generates 1–100 cryptographically random UUID v4s per call using the platform CSPRNG, suitable for idempotency keys, request IDs, and correlation IDs.

How this service works
Use when an agent needs ids that must not collide: cryptographically random UUID v4s, up to 100 in one call, straight from the platform CSPRNG. For idempotency keys, request ids and correlation ids, where a repeat means a duplicate charge or a lost trace. Do not use for a secret or a password (/v1/random/password reports its entropy) or for a hash (/v1/util/sha256).
Output
Returns a JSON object containing the count of UUIDs generated and an array of UUID v4 objects, each cryptographically random and guaranteed collision-resistant, sourced from the platform CSPRNG.
Example use cases
Idempotency keys for payment batch
“I'm about to fire off 25 payment API calls and I need a unique idempotency key for each one — can you generate 25 UUIDs right now?”
Correlation IDs for distributed tracing
“I'm spinning up a microservice pipeline and need 10 fresh UUIDs to use as correlation IDs so I can trace requests end-to-end across services.”
Primary keys for new database rows
“I'm inserting 100 new records into my database and want UUID v4 primary keys for all of them — generate 100 UUIDs please.”
Technical details
Endpoint
GEThttps://flat-rate-llm.kikoribera03.workers.dev/v1/util/uuid?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need bulk, cryptographically secure UUID v4s in a single call without managing your own CSPRNG, especially in serverless or agent contexts where local random generation is unreliable or unavailable. Prefer it over client-side UUID libraries when you want server-side entropy guarantees and up to 100 UUIDs in one round-trip.
Side effects
- count out of range (must be 1–100) — returns an error response
- count not an integer or not parseable as a number — validation error
- upstream CSPRNG or worker failure — 5xx error with no UUIDs returned
