JavaScript SDK

@opendoor/sdk is a fetch client in packages/sdk. It reads OPENDOOR_API_KEY and OPENDOOR_BASE_URL (gateway origin, no /v1 suffix).

Install

From this monorepo:

bashCopy
bun add @opendoor/sdk

Chat

tsCopy
import { OpenDoor } from "@opendoor/sdk";

const client = new OpenDoor({
  apiKey: process.env.OPENDOOR_API_KEY,
  baseURL: process.env.OPENDOOR_BASE_URL ?? "https://opendoor-gcp.web.app",
});

const chat = await client.chat.completions.create({
  model: "gemma-4-26b-a4b-it",
  messages: [{ role: "user", content: "Hello from OpenDoor" }],
});

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

provider is OpenRouter-shaped: { order, allow_fallbacks, sort, only, ignore }. Omit it for the gateway default.

Streaming

tsCopy
const stream = await client.chat.completions.create({
  model: "gemma-4-26b-a4b-it",
  messages: [{ role: "user", content: "Hello" }],
  stream: true,
});

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

OpenAI SDK

tsCopy
import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.OPENDOOR_API_KEY,
  baseURL: "https://opendoor-gcp.web.app/v1",
});

Models, Search, OpenBot

tsCopy
await client.models.list();
await client.plugins.webSearch({ query: "OpenDoor LLM gateway", max_results: 5 });

const agent = await client.agents.create({
  name: "Desk",
  runtime: "openbot",
  modelId: "gemma-4-26b-a4b-it",
});
const turn = await client.agents.chat(agent.id, {
  message: "Open https://example.com and summarize the page.",
});
await client.agents.computer(agent.id, "take");

Search is Vertex grounding at $0.10 / query (included on Enterprise). Agents need the Agents add-on. See Search and Agents.

client.catalog.list() is GET /v1/catalog — every mounted /v1 path.

Errors: OpenDoorError with .status and .body. See Errors and Python SDK.
