Get a free API Passport

A persistent, canonical ECZ-ID for your api — a public identity that resolves live, with a badge, a QR code and a Publish Kit. One sign-in. Nothing to pay.

It records that your api exists and that your organisation claims it.
It is self-declared. It does not say it is verified, assured, safe or approved.
It is not a credential and it is not for sale.
A new version is not a new Passport.

Also free: a Service & Workload Passport, a SDK Passport, a MCP Passport. We never issue one without you asking.
