Quickstart - Gatelit

What is Gatelit?

Gatelit is an AI gateway. It sits between your application and AI providers (OpenAI, Anthropic, Google, Mistral) and gives you:

Single endpoint — one URL, any model, any provider
Unified auth — your users’ tokens, not raw provider API keys in the browser
Provider key management — store keys in the dashboard, rotate without redeploying
Logging — every request logged with model, cost, and latency
Structured output — JSON schema enforcement normalised across all providers

1. Create a service key

Sign in to the Gatelit dashboard and go to Settings → Service Keys. Create a new key and copy it — you’ll use it to authenticate requests.

2. Add a provider key

Go to Settings → Providers and add your API key for at least one provider (OpenAI, Anthropic, Google, or Mistral).

3. Install the SDK

npm install @gatelit/sdk

4. Send your first request

import { GatelitClient } from "@gatelit/sdk"

const client = new GatelitClient({
  gatewayUrl: "https://gateway.gatelit.dev",
  getToken: async () => ({
    token: "glk_your_service_key",
    scheme: "GatelitKey",
  }),
})

const response = await client.chat({
  model: "openai/gpt-4o",
  messages: [{ role: "user", content: "Hello!" }],
})

console.log(response.content)
// → "Hello! How can I help you today?"

Or with curl:

curl https://gateway.gatelit.dev/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: GatelitKey glk_your_service_key" \
  -d '{
    "model": "openai/gpt-4o",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'
