Tools as reported by the server

• get_tool_guide
  Discovery helper: returns the standard prompt template, argument template, output-interpretation guide and related resources for one or all SmartMoney77 tools, so you can call them correctly without guessing. Example: { "tool": "fire_number" }.
• list_calculators
  List every SmartMoney77 calculator with its slug, accepted URL parameters and supported languages/currencies. Call this before build_calculator_link. Example: { "group": "history" } returns only the 'what if I had invested' tools.
• build_calculator_link
  Build a deep link to a SmartMoney77 calculator with pre-filled values that auto-calculate on open. Use list_calculators first to find the slug and its parameters. Example: { "calculator": "bitcoin-history", "lang": "en", "params": { "amount": 1000, "year": 2015 } } → https://smartmoney77.com/en/bitc
• build_share_pack
  Build everything needed to share a SmartMoney77 calculation on social media in one call: the deep link to the result, a ready-to-embed 1200x628 image URL rendered on our servers, a link that opens the on-site share modal (1200x628, 1080x1080, 1080x1920 downloads), and a localized caption with attrib
• compound_interest
  Project the future value of an initial amount plus monthly contributions at a given annual return (monthly compounding), and return a link to the same calculation on SmartMoney77. Example: { "initial": 10000, "monthly": 500, "rate": 8, "years": 20 } → futureValue = 343,778. Monthly contributions are
• fire_number
  Calculate the financial-independence (FIRE) target from monthly expenses using the 4% rule, plus how many years of saving are needed. Example: { "expenses": 4000, "saving": 1500, "current": 50000 } → fireNumber 1,200,000.
• credit_card_payoff
  Calculate how long it takes to clear a credit card balance at a fixed monthly payment and APR, plus the total interest paid. Example: { "balance": 10000, "payment": 400, "rate": 18 } → about 32 months and ~2,600 in interest. Errors when the payment is smaller than the first month's interest.
• emergency_fund
  Calculate how many months of expenses current savings cover, the target emergency fund size, the gap, and how long it takes to close it. Example: { "expenses": 3000, "savings": 6000, "contribution": 500, "target": 6 } → 2 months covered, target 18,000, gap 12,000, 24 months to go.
• inflation_check
  Calculate how much purchasing power cash loses to inflation over time, and what nominal amount keeps the same buying power. Example: { "amount": 100000, "rate": 3, "years": 10 } → realValue ≈ 74,409 and equivalentNeeded ≈ 134,392.
• latte_factor
  Calculate what a small recurring daily expense (coffee, cigarettes, takeaway) costs over time and what it would grow to if invested instead. Monthly cost = cost × perWeek × 52 / 12, and monthly contributions are made at the end of each month (ordinary annuity). Example: { "cost": 5, "years": 30, "ra
• killer_fees
  Compare how much a high management fee costs versus a low fee over time on a portfolio with monthly contributions. Example: { "portfolio": 100000, "monthly": 1000, "highFee": 1.5, "lowFee": 0.3, "years": 25 } → the low-fee portfolio ends materially higher.
• cost_of_waiting
  Compare investing the same monthly amount starting at an early age versus a later age, and show what the delay costs by retirement. Example: { "monthly": 1000, "start": 25, "compare": 35, "retire": 67, "rate": 8 } → a large gap created mostly by compounding, not by the extra contributions.
• historical_investment_return
  Compute what a past investment would be worth today (or in a later year), using the same yearly low/high average prices as the SmartMoney77 history calculators. All amounts and prices are in USD only. Assets: bitcoin, ethereum, solana, sp500, nasdaq100, nvidia, microsoft, meta, apple, tesla, amazon,
• compare_investments
  Run the same "what if I had invested" calculation across 2-8 assets and rank them by final value. USD only, same yearly low/high average pricing as the SmartMoney77 history calculators. Assets: bitcoin, ethereum, solana, sp500, nasdaq100, nvidia, microsoft, meta, apple, tesla, amazon, google, netfli
