xCures
xCures operates the Clinical Clarity Engine, an AI platform that retrieves, organizes and structures fragmented patient medical records into decision-ready clinical data. Founded in 2018 and headquartered in Oakland, California, the company connects to national health information networks (Carequality and TEFCA) to pull a patient's longitudinal record across every provider and care location, then applies LLM-based named-entity/relation extraction and retrieval-augmented checklist assertion to normalize it into FHIR R4 resources, OHDSI/OMOP-mapped vocabularies (SNOMED, LOINC, RxNorm) and HL7 mCODE oncology elements, with every field anchored to its source document. The xCures Public API exposes that engine over REST at partner.xcures.com — patient (Subject) registration, network Query dispatch and polling, document retrieval and reciprocity publishing, FHIR resource reads and bulk export, fifteen Clinical Concepts domains, AI Checklist evaluation and subject summaries — authenticated with OAuth 2.0 client-credentials bearer tokens scoped by a ProjectId header. Originally an oncology real-world-data platform, it expanded to all therapeutic areas and is sold as SaaS, embedded API connections and de-identified real-world datasets to providers, diagnostics companies, value-based-care organizations and channel partners.
xCures publishes 11 API contracts indexed on the APIs.io network, including Application API, Checklist API, Clinical Concepts API, and 8 more. Tagged areas include Health, Healthcare, Medical Records, Interoperability, and FHIR.
The xCures catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.
xCures’ developer surface includes documentation, API reference, getting-started guide, support, engineering blog, signup flow, changelog, and 32 more developer resources.
Kin Score
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 |
|---|---|---|---|---|
| Life Sciences (Biotech and Pharma R&D) | undeclared | - | - | 1 |
| Certified Health IT (health IT accreditation and certification registers) | undeclared | - | - | 1 |
| FHIR Implementation Guides (HL7 FHIR package and IG publishers) | undeclared | - | - | 1 |
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 8
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.
