Keys you control
Up to 5 per account. We keep a SHA-256 hash, never the key. Revoking lands within a minute.
A free API platform by Webrizen AI Labs. Built around the smallest unit of time.
Utility APIs built and hosted by Webrizen, free for every developer. One Webrizen sign-in, one key, plain JSON. No card, no trial, no catch.

02The idea
A chronon is the shortest possible moment. Our APIs aim to cost you about that much.
03Why Chronon
Chronon runs on Webrizen's own servers. Keys and limits exist to share them fairly, never to sell you something.
Up to 5 per account. We keep a SHA-256 hash, never the key. Revoking lands within a minute.
X-RateLimit and X-Quota headers on every response, so you can slow down before you're told to.
Every failure is the same JSON: a stable code, a readable message and a link to the fix.
Plain HTTPS and JSON, CORS open everywhere. No SDK to install, nothing to learn.
Breaking changes ship as /v2. What you build today keeps working tomorrow.
Code, data and limits are MIT-licensed. Fix a dish, add a region, propose an API.
04How it works
The account you already use across Webrizen products. No new password.
Name it after your project and copy it. It's shown once, stored as a hash.
Send it as a bearer token. That's the whole integration.

06Open source
Every endpoint, every dataset and every limit lives in one MIT-licensed repository. Fix a dish, add a region, or propose a whole new API. Review happens in public.
07Fair use
Extra keys never add capacity, and requests turned away by the per-minute window don't count toward your month. Open-source and education projects can ask for more.
How limits work08Questions
Yes. There's no paid plan and nothing to upgrade to. Webrizen builds and hosts the APIs and covers the servers.
Keys aren't for billing. They tell us which account a request belongs to, so limits stay fair and one runaway script can't take the service down for everyone.
You get a 429 with a Retry-After header and a JSON body naming the limit. The headers on every response let you back off before that.
Curated by hand and reviewed in pull requests. Diet labels describe the traditional recipe; check with the kitchen when it matters for allergies or faith.
Open-source, educational and non-profit projects can ask for the Elevated tier (300 a minute, 500,000 a month) by opening an issue.
