Cost Guard: API Budget Enforcer for AI Agents

Stop overpaying for API calls. Cost Guard is an AI agent skill that enforces budgets, tracks token spend, and prevents runaway costs across OpenAI, Anthropic, Google, and any API your agent touches.

Every agent that makes API calls has a cost problem. One infinite loop, one uncached retry storm, one misconfigured model selection — and your bill explodes. Cost Guard watches every request, compares it against budgets you define, and takes action when limits are hit. Not after you see the invoice. In real time.

The skill includes per-model pricing tables so you know exact costs before calls are made, automatic budget enforcement that stops calls when daily or monthly limits are reached, alerting that notifies you before you hit 80% of budget, and detailed cost reports that show exactly where money went. It works with any OpenClaw agent and supports custom rate cards for your specific pricing. Whether you are running a solo agent or orchestrating a fleet, Cost Guard keeps your API spend predictable and transparent. No more surprise bills.
