Flexpa

Flexpa is a patient-access platform that lets applications connect a patient to their health insurance plan and retrieve claims and clinical data as normalized FHIR R4 resources. Patients authorize access through Flexpa Link / OAuth 2.0 PKCE, and applications read ExplanationOfBenefit, Coverage, Patient, and other resources from a single FHIR API at https://api.flexpa.com.

Flexpa publishes 4 APIs on the APIs.io network, including Access Tokens API, Claims Data API, FHIR API, and 1 more. Tagged areas include Healthcare, FHIR, Patient Access, Claims Data, and Health Insurance.

The Flexpa catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Flexpa’s developer surface includes authentication, documentation, engineering blog, changelog, sandbox, API reference, getting-started guide, and 33 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.
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/flexpa: open an issue to ask a question, or submit a pull request to add artifacts. Want it done for you? Prioritized profiling — $2,500 →
