Regulatory Posture applies to this provider. Its tags matched the Telecommunications 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/acoustic: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →

  note: Contract discovery beat a JS-rendered docs host twice. The full Acoustic Content OpenAPI 3.0.0 (136 paths / 178 operations
    / 294 schemas) was extracted from the ReadMe-embedded API definition at /branches/1.0/apis/acoustic-content-api.json on
    developer.goacoustic.com, and a first-party Swagger 2.0 copy (142 paths / 187 operations) was found at github.com/acoustic-content-samples/wch-openapi-documentation.
    Acoustic Campaign turned out to serve a live, unauthenticated Swagger 1.1 service description from every regional pod
    at /restdoc (11 resources, 64 operations), and Acoustic Connect is a GraphQL API whose endpoint is the region host root
    with introspection gated behind X-API-Key. The developer portal also serves a real RFC 9727 /.well-known/api-catalog advertising
    six API products, four more than this profile previously knew about.
