baar-core

About

baar-core prevents unexpected API costs by verifying your budget before each call, immediately raising a local exception if you exceed your limit. This stops charges before any network connection is made, eliminating surprise bills from tasks like an agent running overnight. The tool integrates semantic routing for efficient resource use, offers per-user SQLite quotas, and supports LangGraph with FastAPI. Available under an MIT license, you can install it via pip.
