The tool tracks live API pricing and calculates real costs, highlighting that failed runs, retries, and per-request overhead can significantly inflate the bill. The discussion underscores the need for dashboards to expose token waste from retries and branching parallel calls.", "body_md": "# Title: CostPerPrompt: Live AI API Pricing & Real Cost Calculator\n\nPrice per million tokens is a lie when you're building agents.
