I built a pricing API for LLMs — then realized the real users might not be human

Klikk her: LLM Price Watch started as a simple problem: comparing per-token pricing across Claude, GPT, Gemini, DeepSeek, and Grok meant opening five pricing pages and doing the math by hand every time a new model dropped. So I built a calculator. Then I built an API behind it. Then I noticed something about who was actually going to call that API.

The obvious version

The first version of the API was exactly what you'd expect:

GET /v1/models — every tracked model with current pricing

GET /v1/models/:id — a single model
