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/. This rating is computed from github.com/api-evangelist/cubby: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →

  description: The Cubby Operator API is a JSON HTTP API — explicitly not RESTful — oriented around actions performed on system
    entities rather than transfer of state. Roughly 70 POST endpoints cover access codes, locks, organizations, managers,
    facilities, facility groups, units, pricing groups, customers, leads, leases, payment methods, ledgers, coverage, payments,
    auctions, notes, tasks, reports, storefront search, messaging and checkout. Responses are wrapped in a {status, data}
    envelope, money is expressed as integer cents, timestamps are ISO-8601 with facility-local or UTC semantics, and related
    entities are retrieved through explicit expansions.
