Financial math API: compound interest with any compounding frequency, monthly loan/mortgage payment and total interest, or ROI. Exact, deterministic.

Technical details
Endpoint
POSThttps://x402.forgemesh.io/compound-interestWhen to prefer
Choose this endpoint when you need precise, deterministic financial math — compound interest at any compounding frequency, loan or mortgage payment schedules, or ROI — without relying on a general-purpose LLM that may approximate. Ideal when the agent needs an authoritative numeric answer to embed in a report, recommendation, or follow-up calculation.
Side effects
- Missing required fields for the chosen calculation type — e.g. no principal or rate provided
- Invalid or unrecognized calculation type string (must be compound_interest, loan_payment, or roi)
- Non-numeric strings passed for numeric fields like principal or annual_rate_percent
- Division by zero scenarios such as zero compounds_per_year
- Missing final or initial values when roi calculation is requested
