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/.

  description: Public, unauthenticated Atlassian Statuspage v2 JSON API served on DolarApp's own status host. Exposes overall
    status, the ten monitored components (sign up, sign in, website, and card payments / bank transfers per country for AR,
    MX, CO and US), open incidents and scheduled maintenances. This is the only machine-readable HTTP surface DolarApp/ARQ
    publishes anonymously; it is vendor-provided rather than a first-party developer API.

  detail: DolarApp (rebranded ARQ) runs api.dolarapp.com purely as the backend for its own mobile and business apps — it answers
    every anonymous request, including /openapi.json and /.well-known/*, with HTTP 403 — and the crawlable site map carries
    no /developers, /docs or /api path in any of its twelve locales, so there is no public developer program to profile.
