A server's first observation is its baseline; later probes record what changes.
Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

amortization_scheduleread-only | Principal, interest and remaining balance over the life of one loan. Yearly summary by default; period 'month' gives every payment (up to 120 rows). When optional inputs are omitted, the result includes assumed_defaults (the values actually used) and a short text line so you can call again with those parameters. assumed_defaults is omitted when every optional input was provided. |
calculate_auto_loanread-only | Monthly payment, amount financed, total interest and total cost for one US car loan. Amount financed = price − down − trade-in + owed on trade-in; sales tax and fees are paid upfront unless tax_and_fees_financed is true, then they are added to the loan. total_cost = cash due at purchase + all payments (price + tax + fees + interest − trade-in + owed). Returns the inputs echoed back and a carloanmath.com share_url. When optional inputs are omitted, the result includes assumed_defaults (the values actually used) and a short text line so you can call again with those parameters. assumed_defaults is omitted when every optional input was provided. |
compare_auto_loansread-only | Side-by-side comparison of 2–4 loan scenarios (e.g. 60 vs 72 months, dealer vs credit-union APR, more down). Each result has a share_url; differences are against the first scenario, plus which is cheapest overall and lowest monthly. When optional inputs are omitted, the result includes assumed_defaults (the values actually used) and a short text line so you can call again with those parameters. assumed_defaults is omitted when every optional input was provided. On this tool, assumed_defaults is per scenario; a top-level assumed_defaults is included only when country was omitted. |
max_vehicle_price_for_budgetread-only | Reverse calculation: the highest vehicle price whose monthly payment stays within monthly_budget, for one or more terms. Uses the same tax, fee, down payment and trade-in rules as calculate_auto_loan. Each row includes the check calculation and its share_url. When optional inputs are omitted, the result includes assumed_defaults (the values actually used) and a short text line so you can call again with those parameters. assumed_defaults is omitted when every optional input was provided. |
