Installation

Use Captar when you want runtime controls inside your application rather than a proxy or gateway layer. The install footprint is intentionally small: the SDK, your provider client, and whatever exporter configuration you choose for traces. 
pnpm add @captar/sdk openai

​
Environment

OPENAI_API_KEY=...
CAPTAR_INGEST_URL=http://localhost:3000/api/ingest
CAPTAR_INGEST_API_KEY=

​
Base runtime

import { createCaptar } from "@captar/sdk";

export const captar = createCaptar({
  project: "support-bot",
  exporter: {
    url: process.env.CAPTAR_INGEST_URL!,
    apiKey: process.env.CAPTAR_INGEST_API_KEY,
  },
});

​
After install

  1. Create a runtime module you can import anywhere in your app.
  2. Store project defaults in one place, not inline in every request handler.
  3. Decide whether exporter settings come from environment variables or code.
  4. Start with one session path, then add policies and tool tracking.
Captar v1 is intentionally optimized for OpenAI and OpenAI-compatible request flows. Other provider integrations should stay out of scope for now.
