@trustmodel/sdk

Official TypeScript / Node SDK for TrustModel — AI trust evaluation, OpenTelemetry telemetry, and agent governance (AGP). Parity with the Python SDK (trustmodel on PyPI) for the three core surfaces.

Status: scaffold under review. Core client (eval / AGP) lands next; telemetry (autoInit) is scaffolded. See docs/DESIGN.md.

Install

npm install @trustmodel/sdk
# Telemetry (OTel) is optional — install the OTel peers only if you use autoInit():
npm install @opentelemetry/api @opentelemetry/sdk-trace-node \
  @opentelemetry/exporter-trace-otlp-http @opentelemetry/resources \
  @opentelemetry/semantic-conventions

Requires Node >= 22.12.

One-command agent eval (CLI)

npm i @trustmodel/sdk
export TRUSTMODEL_API_KEY=tm-...
npx trustmodel eval-agent           # auto-detects .codenow/runs recordings → TrustScore
# npx trustmodel eval-agent --trace trace.json --agent my-agent

Quick start

import { TrustModelClient } from "@trustmodel/sdk";

const tm = new TrustModelClient({ apiKey: process.env.TRUSTMODEL_API_KEY });

// Model eval → TrustScore
const run = await tm.evaluations.create({
  modelIdentifier: "gpt-4o",
  vendorIdentifier: "openai",
});

// Agent eval — one call, no upload dance (inline trace)
const agentRun = await tm.agentic.evaluate({
  trace: { goal: "Book a flight", steps: [{ step_type: "final_answer", content: "Booked" }] },
  agentFramework: "langchain",
  governedAgent: "my-agent",   // binds the score to the AGP agent
});

// Governance — gate a tool call
const decision = await tm.agp.decide({
  tool: "send_email",
  args: { to: "ceo@acme.com" },
  agentId: "my-agent",
});

Telemetry (OTel) — SKU2

Dependency-free, edge-safe OTLP export (Node, Deno, Bun, Workers) — no @opentelemetry/* required. Wrap work in span(); traces stream to TrustModel with the trustmodel.agent_id binding the backend needs.

import { autoInit } from "@trustmodel/sdk/telemetry";

const tm = autoInit({
  apiKey: process.env.TRUSTMODEL_API_KEY!,
  agentId: "my-agent",     // → trustmodel.agent_id (binds to your agent)
  domain: "general_ai",
});

const answer = await tm.span("llm.call", async () => callOpenAI(prompt), { model: "gpt-4o" });

await tm.flush();      // send buffered spans (also auto-flushes on a timer + on exit)

Automatic instrumentation (openai / anthropic / langchain)

Opt-in, zero-code capture via OpenInference — install the OTel + instrumentor peers, then:

npm i @opentelemetry/sdk-trace-node @opentelemetry/sdk-trace-base \
  @opentelemetry/exporter-trace-otlp-http @opentelemetry/resources @opentelemetry/instrumentation \
  @arizeai/openinference-instrumentation-openai   # + -langchain / -anthropic as needed

import { enableAutoInstrumentation } from "@trustmodel/sdk";

const ai = await enableAutoInstrumentation({
  apiKey: process.env.TRUSTMODEL_API_KEY!,
  agentId: "my-agent",
  domain: "general_ai",
});
// Every openai/anthropic call is now traced to TrustModel automatically.
// ai.installed → the instrumentors that were wired

The dependency-free autoInit() above needs none of these — it's the edge-safe path. enableAutoInstrumentation() is the full-OTel path for Node when you want zero-code capture.

Configuration

Option	Env	Default
apiKey	TRUSTMODEL_API_KEY	—
baseUrl	TRUSTMODEL_BASE_URL	per environment
environment	—	production (qa, local)
organizationId	TRUSTMODEL_ORGANIZATION_ID	— (→ X-Organization-ID)
edgeUrl	TRUSTMODEL_EDGE_URL	— (guardrails Edge)

Auth is Authorization: Bearer <apiKey> — identical to the Python SDK.
