What I built
A local FastAPI reverse proxy and Streamlit dashboard that logs LLM token usage, latency, task tags and YAML-configured pricing to SQLite with budget alerts and deterministic mock mode.
Developed with AI coding assistance. Source code, reproduction instructions and tests are available in the linked repository.
What was checked
20 automated pytest checks passed locally on 2 November 2026.
Verification date: 2 November 2026. Tests cover the included fixtures and do not establish production performance.
What this demonstrates
Tracks token usage and estimated cost against local YAML price tables. Mock-mode and local proxy tests do not verify third-party provider billing accuracy or multi-tenant production security.
