AgentCore Pricing

Critical Rules

• NEVER use training data for prices. All prices must come from cached JSON files at runtime.
• NEVER implement billing formulas manually. Always use calculate_agentcore_cost() and calculate_evaluation_cost().
• Only include components explicitly requested. If user says "run in AC Runtime," add ONLY Runtime — do not auto-add Gateway, Memory, etc.
• STM reads are free — only writes are billed.
• vCPU is free during I/O wait — do not apply I/O wait discount to BrowserTool or CodeInterpreter.
