Introduction

What is Tallyify?

Tallyify is an AI usage telemetry and cost tracking platform. Monitor your LLM API costs across OpenAI, Anthropic, Google Gemini, and more — all in one dashboard.

What is Tallyify?

Tallyify gives you a unified view of how your application consumes LLM APIs. Instead of checking each provider's dashboard separately, install our lightweight SDK, wrap your AI calls, and see every token and every cent in one place.

It's completely transparent — the SDK intercepts completed responses (never blocking them), extracts token usage from the standard response format, and sends telemetry asynchronously in the background.

Key Features

• Multi-provider support — OpenAI, Anthropic, Google Gemini out of the box.
• Zero-latency tracking — fire-and-forget telemetry never blocks your critical path.
• Cost estimation — token counts translated into cost estimates based on current pricing.
• API key management — create, scope and audit SDK keys from your dashboard.
• Price comparison — compare 200+ AI models and track price changes with watchlist alerts.

How It Works

The integration works in three steps:

1. Install the SDK — one npm package, no extra infrastructure.
2. Wrap your AI call — pass your existing promise to tracker.track().
3. View in dashboard — token counts and costs appear in real-time.

import { Tracker } from '@tallyify/sdk';
import OpenAI from 'openai';

const tracker = new Tracker({ apiKey: process.env.TALLYIFY_API_KEY });
const openai = new OpenAI();

const response = await tracker.track(
  openai.chat.completions.create({
    model: 'gpt-4o',
    messages: [{ role: 'user', content: 'Hello!' }]
  })
);
