Cal.com API v2
What it says
Nothing read yet
An API specification its publisher serves: reference material for whoever writes the client, not something that runs on its own.
What this is
API spec
application/vnd.oai.openapi+jsonlast seen 2026-10-04
These are the publisher's own words, read from what they serve at their own address.
Terms
A description, not an offer
The publisher has signed no standing terms for this, so anything said here about price describes what they charge rather than binding them to it. Agreeing terms is between you and them.
Where it lives
The publisher's own address

This catalog links to it and never serves a copy, so what you get is whatever cal.com is serving now.
In its own words
What its publisher says you would ask it
