Ideal for AI agents that already have the loan parameters and need a reliable, fast breakdown of payment schedules. Prefer over general-purpose LLM math when you need precision and a structured, machine-readable result. Use when the agent must handle financial calculations at scale via micropayment-gated API rather than a stateful financial platform.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-09-15T18:43:33.361Z","isFirstParty":false}
