Quenza

Quenza is a digital care and client-engagement platform for coaches, therapists, and other helping professionals. Practitioners build activities - worksheets, exercises, psycho-education, intake forms, reflection prompts, and surveys - bundle them into timed pathways (care programs), and share them with clients through a branded client portal and mobile apps, then track responses, results, notes, tasks, and chat. Quenza exposes a documented public REST API (v1) for programmatically managing clients, team members, groups, and tasks, authenticated with a workspace Bearer token. API access is available on the Collective and Beyond plans; webhooks are available from the Growth plan up.

Quenza publishes 4 API contracts indexed on the APIs.io network, including Clients API, Groups API, Members API, and 1 more. Tagged areas include Coaching, Therapy, Client Engagement, Digital Health, and Mental Health.

The Quenza catalog on APIs.io includes 1 Spectral governance ruleset.

Quenza’s developer surface includes engineering blog, pricing, authentication, documentation, and 10 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health 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.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Health and Wellness (consumer health, fitness, wearables)	undeclared	-	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 1

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
