I built this after hitting the same wall repeatedly — no good
way to enforce token budgets in application code. Provider
caps are account-level and tell you what happened, not what
is happening.
Two ways to add it:
# Direct client wrapper
client = tokencap.wrap(anthropic.Anthropic(), limit=50_000)
# LangChain, CrewAI, AutoGen, etc.
tokencap.patch(limit=50_000)
Four actions at configurable thresholds: WARN, DEGRADE
(transparent model swap), BLOCK, and WEBHOOK. SQLite out of
the box, Redis for multi-agent setups.
One design decision worth mentioning: tokencap tracks tokens,
not dollars. Token counts come directly from the provider
response and never drift with pricing changes.

Happy to answer any questions.
