agentbelt-budget
A lightweight, in-process circuit breaker for LLM token and cost spend. Part of the agentbelt suite.
pip install agentbelt-budget
Quickstart
from agentbelt_budget import Budget, CircuitBreaker, BudgetExceeded
breaker = CircuitBreaker(Budget(max_tokens=100_000, max_cost_usd=5.0, window="24h"))
try:
breaker.check("session-123")
response = call_llm(prompt)
breaker.record_response("session-123", response, model="gpt-4o")
except BudgetExceeded as e:
print(f"blocked: {e}")
What did this actually catch?
print(breaker.impact_report())
# 5 call(s) blocked across 1 session(s) before exceeding budget (1 distinct trip event(s))
Countable events (calls blocked, distinct sessions, trip count) — not a
dollar estimate, since there's no way to know what a blocked call would
have actually cost. .metrics on the returned ImpactReport gives the
same numbers as a plain dict if you want to log or export them.
See the suite README for the
full concept and how this fits with agentbelt-loop and
agentbelt-sampler.
