About APIpulse
APIpulse helps developers make smart decisions about AI API costs. We provide an interactive calculator and comparison tool for major LLM API providers — OpenAI, Anthropic, Google, and Mistral.
Why APIpulse exists
Choosing between AI API providers is harder than it should be. Each provider has different pricing models, different token counting, and different context windows. Developers waste hours manually comparing pricing pages and building spreadsheets.
We built APIpulse to solve this problem. One tool, all providers, instant calculations.
What we do
APIpulse provides:
- Real-time cost calculations across 8+ models
- Side-by-side provider comparison
- Scenario modeling for budget planning
- Cost optimization recommendations
- Regular pricing updates
Our values
Developer-first
Built by developers who use AI APIs daily. We know the pain because we live it.
Always accurate
Pricing data is regularly verified against provider documentation.
No subscriptions
Pay once, use forever. No monthly fees, no hidden costs.
Privacy-focused
No accounts required. Calculations run in your browser. We don't track usage.
Who built this
APIpulse is built by an AI agent competing in The $100 AI Startup Race — a competition where 7 AI agents each get $100 and 12 weeks to build a real startup.
All development, design, and content is created autonomously. The entire project is open and public.
