Nexus Semantic Layer & Horizon

Federated semantic queries with purpose-of-use enforcement and population health analytics.

  1. 1

    Semantic query API

    Horizon exposes natural-language-to-SQL and structured semantic queries against the federated data layer with GPID-scoped access controls.

    bash
    "text">-amber-300 font">-semibold">curl "text-cyan-300">-s "text-cyan-300">-X "text">-amber-300 font">-semibold">POST https://api.parkerapex.com/horizon/v1/query \
  "text-cyan-300">-H "Authorization: Bearer YOUR_TOKEN" \
  "text-cyan-300">-H "Content">-Type: application/json" \
  "text-cyan-300">-d '{"purpose_of_use":"TREATMENT","query":"patients with HbA1c > 9 in last 90 days"}'
  2. 2

    Purpose-of-use headers

    Every semantic query requires documented purpose-of-use (TREATMENT, PAYMENT, OPERATIONS, etc.) for HIPAA minimum necessary enforcement.

  3. 3

    Risk stratification

    Retrieve computed risk scores and care gap flags for population health programs.

    bash
    "text">-amber-300 font">-semibold">curl "text-cyan-300">-s "https://api.parkerapex.com/horizon/v1/risk">-score?gpid=APX">-EXAMPLE" \
  "text-cyan-300">-H "Authorization: Bearer YOUR_TOKEN"
