Passport

Passport (Passport Labs) is a mobility management platform for cities, universities, and agencies, covering digital parking payments, enforcement, permits, and curbside management, and is used by 800+ agencies. Passport exposes a partner developer program at developer.passportinc.com whose REST APIs let parking apps, navigation apps, in-car infotainment, and mobility/POS systems create and stop parking sessions, quote and determine rates, bulk-export the parking environment (zones, spaces, rules), receive parking event schemas, and manage enforcement immobilizations. Rates and rules are configured once by Passport's customers and pushed to payment providers via API. Access is gated - partners register an application, are issued OAuth client credentials by Passport's identity provider, and only authenticated partner applications may call the public APIs. No SDK is required. Commercial terms are partnership / agency-contract based rather than publicly listed self-serve pricing.

Passport publishes 5 APIs on the APIs.io network. Tagged areas include Parking, Mobility, Smart Cities, Payments, and Enforcement.

Passport’s developer surface includes documentation, engineering blog, and 5 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/.
