Tools 11 found in our last check

• get_exchange_rate

  Use this when the user asks 'what is X in Y?', 'convert X to Y', 'current rate of EUR/USD', or any single fiat-to-fiat exchange rate question. Returns { rate, source } meaning 1 source = rate target. Without an API key it answers from the official ECB daily reference table (~30…

• get_historical_rates

  Fixed-window time series ending now: 'how has EUR/USD moved this week', 'last month of GBP/JPY', '1-year AUD/USD'. Returns { source, target, period, data: [{ date, rate, timestamp }] }. Sampling: 1d=hourly, 7d/30d=daily, 1y=weekly. Requires an API key on a paid plan; free and tr…

• get_rates_authenticated

  One source against several targets in a single call ('USD vs EUR, GBP, JPY'), or the rate at a specific past datetime, optionally bucketed by hour/day/week/month. Returns { rates: [{ rate, source, target, time }] }. Requires an API key (free tier for latest rates; a past datetim…

• list_currencies

  Call this when unsure whether a currency code is supported, or for 'what currencies do you support?' / 'what is the symbol for X?'. Returns { currencies: [{ code, name, symbol }], count } for 150+ ISO 4217 fiat currencies. No API key needed; cheap to call.

• list_central_banks

  Call this FIRST when you need a bank code, or for 'which central banks do you cover?' / 'do you have rates from X?'. Returns every covered source — 123 central banks plus 6 tax authorities (HMRC, US Treasury, Swiss BAZG, India's CBIC, Peru's SUNAT, US IRS yearly averages) — with…

• get_official_rates

  OFFICIAL rates a named institution published — 'what is the ECB rate for USD?', 'Bank of Japan rate on 2026-03-14', 'HMRC rate for invoicing'. These are the fixed, citable rates for compliance, tax, customs and accounting — NOT live market rates. Omit `date` for the newest publi…

• get_official_rate_history

  Date-by-date series of one bank's OFFICIAL rates — 'ECB USD rate for every day of 2025', 'how did the CBSL rate move last quarter'. Returns { series: [{ date, rate, rate_type, derived, method }] }. Give either `symbol` (vs the bank's home currency) or a source+target pair; from/…

• compare_official_rates

  One currency pair across ALL institutions at once — 'what does each central bank say USD/EUR is?', 'spread between official USD/LKR rates'. Returns every covered bank's latest official rate for the pair plus { min, max, median, spread_bps } over fresh sources. Banks are never mi…

• get_publication_calendar

  Which dates a bank actually published a rate table — 'did the ECB publish on 2026-01-01?', 'how often does the US Treasury publish?'. Dates only, no values, so it is on every plan (API key required, free tier). Give `year` or a from/to range; large ranges are capped and flagged…

• get_reference_rate

  AllRatesToday's once-a-day, never-revised mid-market rate: the per-currency median of five samples in a five-minute window centred on 16:00 London, published each business day. Use it when the user needs ONE reproducible rate per day — index levels, return series, research datas…

• request_trial_key

  Self-issue an AllRatesToday API key with 100 lifetime calls, valid 7 days, with no account and no email. Use it when another tool answered "needs an API key" and the user wants real-time rates, history, dated central-bank tables or cross-bank comparison right now. The key is ret…
