How this service works
Pay-per-call tools for people building AI agents: live web search and page contents, point-in-time crypto market data and news for backtests (no lookahead), verifiable track records of 1,000 crypto strategies locked on the Base network, company profiles, quick AI and batch prices. Ask us to turn a public website into a JSON endpoint. Pay per call, no account, free trial.
Output
A JSON object containing the operation type and relevant computed financial metrics — for a loan: monthly payment, total paid, and total interest; for compound interest: final balance; for NPV/IRR: present value or rate; for ROI: return percentage.
Example use cases
Mortgage payment planning
“What would my monthly payment be on a $550,000 home loan at 6.75% interest over 30 years, and how much total interest will I end up paying?”
Compound savings growth projection
“If I invest $10,000 now at 7% annual return and add $500 every month, how much will I have after 20 years with monthly compounding?”
Investment ROI evaluation
“I bought something for $25,000 and sold it for $38,000 after 3 years — what's my annualized return on investment?”
Technical details
Endpoint
GEThttps://api.manylives.me/paid/calc/finance?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs quick, pay-per-call financial math without setting up an account or a dedicated financial library — especially useful for loan analysis, investment evaluation, or compound growth projections in agentic finance workflows. Ideal for agents that need ad-hoc financial calculations billed via USDC micropayments on Base.
Side effects
- Missing required 'op' parameter returns error
- Invalid or missing required parameters for the selected operation (e.g. no principal for loan) causes calculation failure
- Malformed cash flow list for NPV/IRR causes parse error
- Payment required if USDC micropayment not included in request
- Non-numeric values for numeric fields cause errors
