I Got a $400 AI API Bill I Didnt Expect - So I Built CostPulse

The Wake-Up Call

Last month I opened my OpenAI billing dashboard and saw $400.

I had been running experiments. Testing features. Building prototypes. Each API call seemed small, but they added up fast.

The Problem

  • No real-time visibility into API spend
  • Forecasting is nearly impossible
  • By the time you see the bill, it is too late
  • Cost centers are hard to attribute to specific projects

What I Built

CostPulse.ai - Real-time API cost forecasting for AI developers.

Features

  • Connect your OpenAI/Anthropic accounts
  • See costs as they happen (not 30 days later)
  • Get alerts before you hit your budget
  • Forecast end-of-month spend
  • Attribute costs to projects/users/features

The Math

If you are spending more than $50/month on AI APIs, you need visibility.

One unexpected spike can cost more than CostPulse would have saved you.

Pricing

  • Free: 1 API key, daily updates
  • Pro ($19/mo): Unlimited keys, real-time alerts, forecasting

Visit: costpulse-cypress-signal.vercel.app


How do you track your AI API costs? Has anyone else been surprised by a bill?
