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/.

    carries the routing decision (route.type of skill, external, agent or hangup, plus route.value and route.reason), static
    meta.* fields from the integration and transfer-destination configuration, task.* attributes including the task SID, and
    definedContactData.* values collected by Set Contact Data actions in the Agent Builder. Regal documents this endpoint
    as currently enabled only for inbound calls connected through the Five9 AI Agent Connect integration, at 10 requests per
    second.
