Qwil

Qwil (qwil.co) is a financial-technology company and a 500 Global portfolio company. It operates a consumer-facing web and mobile application ("Qwil WebApp" at app.qwil.com) backed by a private, authenticated REST API at api.qwil.co. The platform connects to users' bank accounts through Plaid and uses Firebase Authentication (Google Identity Platform) for identity, with bearer tokens presented to a Django REST Framework API. Qwil does not publish a public API specification, developer portal, or SDK documentation; the API is private and partner-gated. Note that qwil.co is distinct from Qwil Messenger (qwil.io), an unrelated secure client-collaboration platform. This profile was enriched by live probing of Qwil's public network surface; most standard developer artifacts are unavailable because Qwil exposes no public developer program.

Qwil publishes 1 API on the APIs.io network. Tagged areas include Company, Fintech, Financial-Services, Payments, and Banking.

Qwil’s developer surface includes authentication and 4 more developer resources.

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