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 API contracts indexed 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, 1 JSON-LD context, and 1 Spectral governance ruleset.

Flexpa’s developer surface includes authentication, documentation, engineering blog, changelog, sandbox, API reference, getting-started guide, and 41 more developer resources.

What people ask Flexpa 4

The questions people put to an LLM, and the jobs they hand an agent, that Flexpa's APIs answer — each one linked to the operation that does it. Generated by API Evangelist

Flexpa FHIR API Check which FHIR resources the server supports “Which FHIR resources and operations does the Flexpa server support?” Search patients by identifier “Can I find a Patient resource using an identifier such as a member ID?” Get a patient's demographic record “How do I read one patient's demographics once I have their Patient ID?” Search a patient's insurance coverage “Which health insurance plans cover a given patient?”

Flexpa Claims Data API Get every record for a patient “Can I pull every resource in a patient's compartment in a single call instead of searching each type?” Generate an International Patient Summary “Can I generate an International Patient Summary (IPS) document for a connected patient?” Export a patient's health data as a PDF “Can I export a patient's health data as a printable PDF?” Search a patient's insurance claims “How do I list a patient's health insurance claims as ExplanationOfBenefit resources?”

Flexpa Link API Start a patient's health plan authorization “Where do I send a patient so they can pick their health insurance plan and authorize my app in Flexpa Link?”

Flexpa Access Tokens API Exchange a code or refresh an access token “What do I send to Flexpa to swap a Link authorization code and PKCE verifier for a Patient Access Token?”

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/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. 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.

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
Healthcare (FHIR)	standard	20.2 (thin)	-	-

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.
