Healthcare APIs that don't fight you.
One coherent API surface for the entire Apex Ecosystem. FHIR R5 native, OAuth 2.0 / SMART on FHIR auth, six first-party SDKs, and sandbox keys in 30 seconds.
Resolve an identity. Stream a query.
Two API calls. One canonical patient identity. A streaming FHIR R5 result set, end-to-end. Same SDK, same auth, every module.
import { Parker } from "@parker/sdk";
const parker = new Parker({
apiKey: process.env.PARKER_SANDBOX_KEY,
env: "sandbox",
});
// Resolve a brand-new patient record to a canonical GPID
const id = await parker.gpid.resolve({
given: "Alex",
family: "Rivera",
dob: "1984-03-12",
source: "epic://memorial-clinic",
});
// Stream a FHIR R5 query through Nexus
for await (const r of parker.nexus.search({
resourceType: "Observation",
patient: id.gpid,
code: "loinc|4548-4", // HbA1c
})) {
console.log(r);
}One auth, every module.
Read and write across every connected EHR via a single, sub-120ms FHIR R5 endpoint. SMART on FHIR, Bulk Data Export, and USCDI v4 native.
Generate cohorts on demand from the Atlas synthetic population. Apache 2.0 for non-production; commercial keys for production deployment.
Query the dual-verified record store. Filter by source, signer, code system, or cryptographic chain.
Resolve any inbound clinical record to a canonical GPID, with a confidence score and signed evidence trail.
Tail the live signed-event stream for any tenant. Webhook delivery, gRPC streaming, or SIEM-friendly JSON pull.
Healthcare-aware payment primitives, FedNow rails, HSA/FSA-aware ledgering, and instant settlement endpoints.
Six languages, first-party.

Sign in with GitHub, get a sandbox key. No sales call, no credit card, no PHI involved.
Subscribe to any signed event from Beacon. Replay, filter, and back-test webhook handlers from the dashboard.
EHR-native auth out of the box. Standard scopes, refresh tokens, and patient/encounter context automatically threaded.
Date-stamped API versions, six-month deprecation windows, and a public changelog with every release.
Parker runs its own mission control.
Every API call, every webhook delivery, every identity resolution flows through the Parker API Command Center — the operational surface our team uses internally, and the same one we open to design partners. Latency, error rate, signed audit chain, and per-tenant throughput, all in one console.
Every endpoint, every tenant, sub-second.
Lift limits, mint scoped keys, rotate secrets.
Replay any signed event, end-to-end.
Per-module status, incident history, RCA.
Build with us.
Design partners get scoped sandbox keys, a direct line to engineering, and early access to APIs as they enter beta. We respond within two business days.
- Scoped, time-bound sandbox keys
- Per-tenant rate ceilings on request
- Shared Slack/Signal channel with the API team
- Pre-release access to new module APIs
