Wildly unique IDs.
A simple HTTP API for UUIDs. Make one request, get one unique identifier back — v4 or v7, authenticated, rate-limited, and metered. Nothing to install, nothing to maintain.
Everything an identifier needs.
Nothing it doesn't.
One endpoint
Send a request, get a UUID. The whole API is a single call you'll remember after reading it once.
v4 & v7
Random or time-sortable. Add ?version=7 when you need ordering, leave it off when you don't.
Batch requests
Need many at once? /v1/uuid/batch returns up to your plan's limit in a single round trip.
API keys
Authenticate with a bearer token. Keys are hashed at rest, scoped per environment, and rotate anytime.
Usage you can see
Every request shows up in your dashboard. Clear quotas, clear counts, no surprise invoices.
Predictable limits
Per-key rate limits with standard headers, so you always know where you stand before you hit them.
Pay for IDs. That's it.
