Worthune is a financial modeling API providing verified results for complex financial decisions. Each model includes a published specification with formulas and input ranges, an independent implementation, 250 test cases for consistency, sourced constants with verification dates, a public changelog, and cryptographic hashes to ensure integrity. The platform supports calculations for housing, retirement, equity compensation, insurance, debt, and life events. Integration options include REST API, Model Context Protocol for AI assistants, or embedded calculators. Its verification feature assesses financial claims as verified, violated, or out-of-scope. Organizations can compare their calculation engines to Worthune's models to identify discrepancies. The system also generates print-ready reports with cryptographic proofs. FinPlanBench provides an open benchmark for testing financial model accuracy against standardized cases.
