Official TypeScript SDK for the ClarisMD governed-AI gateway for healthcare — PHI scanning, policy enforcement, audit logs, and OpenAI-shaped chat / embeddings, exposed through a single client.

• Isomorphic. Native fetch only. Works in Node 18+, modern browsers, Cloudflare Workers, Deno, and Bun.
• Zero runtime dependencies. ≤ 15 kB gzipped.
• Strict TypeScript. Hand-written types ship today; OpenAPI codegen drops in once packages/openapi/v1.yaml stabilizes.

ClarisMD is healthcare infrastructure. The SDK does not transmit PHI on its own — it is the caller's responsibility to set the gateway policy headers (X-ClarisMD-Policy, X-ClarisMD-PHI-Action) appropriately. No real PHI on hosted demos — use synthetic data only.

Install

From npm (recommended):

npm install @clarismd/sdk
pnpm add @clarismd/sdk
yarn add @clarismd/sdk
bun add @clarismd/sdk

From the public GitHub repo (latest main, or pin to a tag/commit):

npm install github:amanjaiswal777/clarismd-node
npm install github:amanjaiswal777/clarismd-node#v0.1.0
npm install git+https://github.com/amanjaiswal777/clarismd-node.git#<commit-sha>

In a package.json:

{
  "dependencies": {
    "@clarismd/sdk": "github:amanjaiswal777/clarismd-node#v0.1.0"
  }
}

For local development:

git clone https://github.com/amanjaiswal777/clarismd-node.git
cd clarismd-node
npm install
npm run build && npm test

Requires Node.js 18+. Also runs unmodified on modern browsers, Cloudflare Workers, Deno, and Bun.

Quickstart

import { ClarisMD } from "@clarismd/sdk";

const client = new ClarisMD({ apiKey: process.env.CLARISMD_API_KEY });

const completion = await client.chat.completions.create({
  model: "gpt-4o-mini",
  messages: [{ role: "user", content: "Summarize this discharge note." }],
});

console.log(completion.choices[0]?.message.content);

Migrating from the OpenAI SDK

Drop-in compatible — change two lines:

-import OpenAI from "openai";
-const client = new OpenAI({ apiKey: process.env.OPENAI_API_KEY });
+import { ClarisMD } from "@clarismd/sdk";
+const client = new ClarisMD({ apiKey: process.env.CLARISMD_API_KEY });

Self-hosting / private gateways

const client = new ClarisMD({
  apiKey: process.env.CLARISMD_API_KEY,
  baseURL: "https://gateway.internal.example.com/v1",
});

baseURL also resolves from CLARISMD_BASE_URL if you'd rather keep it out of code.

Verify the gateway is reachable (no API key required server-side):

const status = await client.health.check();
console.log(status.status, status.version); // "ok" "0.4.2"

Streaming

const stream = await client.chat.completions.create({
  model: "gpt-4o-mini",
  messages: [{ role: "user", content: "Stream me a haiku." }],
  stream: true,
});

for await (const chunk of stream) {
  process.stdout.write(chunk.choices[0]?.delta.content ?? "");
}

Mid-stream errors raise the same typed exceptions as synchronous calls — e.g. PHIPolicyViolationError when the gateway blocks an in-flight generation.

PHI scan

const result = await client.phi.scan(
  "Patient John Doe, DOB 1970-01-01, called about test results.",
);
console.log(result.detected, result.entities);

Audit logs

const page = await client.audit.list({
  startDate: new Date("2026-04-01"),
  endDate: new Date("2026-05-01"),
  phiDetected: true,
  limit: 100,
});

const blob = await client.audit.export({ format: "json" });
// In Node: await Bun.write("audit.json", blob); or fs.writeFileSync(...)

Compliance dashboard

const score = await client.compliance.score({ framework: "hipaa" });
const requirements = await client.compliance.requirements();
const evidence = await client.compliance.evidence(requirements[0]!.id);
await client.compliance.acknowledge(requirements[0]!.id, {
  status: "acknowledged",
  notes: "Reviewed Q2 2026",
});

Error handling

Every error inherits from ClarisMDError. Inspect instanceof for typed handling:

import {
  PHIPolicyViolationError,
  RateLimitError,
  APITimeoutError,
} from "@clarismd/sdk";

try {
  await client.chat.completions.create({ ... });
} catch (err) {
  if (err instanceof PHIPolicyViolationError) {
    // gateway blocked the request — fall back to a redaction flow
  } else if (err instanceof RateLimitError) {
    // 429 — backoff
  } else if (err instanceof APITimeoutError) {
    // network slow — retry or escalate
  } else {
    throw err;
  }
}

The SDK retries 429 / 5xx / network failures automatically with exponential backoff (500 ms, 1 s, 2 s) plus ±25% jitter; Retry-After is honored, capped at 60 s. Override per request:

await client.chat.completions.create({ ... }, { maxRetries: 0 });

AbortSignal

const controller = new AbortController();
setTimeout(() => controller.abort(), 30_000);

await client.chat.completions.create(
  { model: "gpt-4o-mini", messages: [...] },
  { signal: controller.signal },
);

ClarisMD-specific options

Per-request:

| Option | Header | Purpose | |---|---|---| | clarismdPolicy | X-ClarisMD-Policy | Override the gateway policy for this call | | clarismdPhiAction | X-ClarisMD-PHI-Action | One of block, redact, tokenize, alert | | idempotencyKey | Idempotency-Key | Pass false to disable; pass a string to set verbatim |

POSTs auto-generate Idempotency-Key: cmd-ts-${uuid} unless explicitly disabled.

Browser usage

Don't ship your gateway API key in browser-side JavaScript. Mint a short-lived scoped key on your backend and inject it into the page or exchange it via your own auth endpoint. The SDK runs in browsers; that doesn't mean a long-lived key is safe in one.

Cloudflare Workers

The SDK targets ES2020 + the standard fetch / Response / ReadableStream / crypto.randomUUID APIs available in Workers. See examples/cloudflare-worker.ts for an end-to-end fetch handler.

Examples

Runnable scripts live in examples/:

• quickstart.ts — basic chat completion
• streaming.ts — server-sent-events streaming
• phi-scan.ts — PHI entity detection
• audit-export.ts — pull a signed evidence bundle
• compliance-score.ts — auto vs. manual breakdown
• cloudflare-worker.ts — end-to-end Workers fetch handler
