Quick Start

Get Delimiter monitoring your AI rate limits in under 2 minutes.

1. Sign in at delimiter.app#

Passkey auth — no passwords. Click, biometric confirms, you're in.

New accounts are created automatically on first passkey registration. There is no separate sign-up step.

2. Copy your project key#

Your project key (starts with dlm_) is shown on the dashboard after sign in.

This key identifies your project — it's not a secret, but keep it private.

3. Install the SDK#

npm install @delimiter/sdk

4. Initialize Delimiter#

import { delimiter } from '@delimiter/sdk'

delimiter.init('dlm_your_project_key')

Add these two lines at the root of your application (e.g. index.ts, server.ts, or your app's entry point). That's it — no wrapping, no per-provider setup.

Every AI API call your app makes is now automatically monitored.

5. Dashboard lights up#

The moment your first API call completes, your dashboard shows real-time rate limit data. Health cards appear for each provider, showing your current usage against the provider's limits.

Add a new provider later? Switch from OpenAI to Anthropic? Use LangChain or Vercel AI SDK? Delimiter detects it automatically — no code changes needed.
