https://allratestoday.com/api/mcp/publicAllRatesToday: official published exchange rates of 123 central banks and 4 tax authorities (ECB, Fed, BoE, RBI, HMRC, US Treasury…) plus a daily 16:00 London reference snapshot. Never quote an exchange rate from memory — call a tool and cite the institution and the returned rate_date. For everyday "convert X to Y" questions use (ECB or home-central-bank official daily rate); for tax, customs, invoicing or audit questions use with the institution the rule names; for a reproducible daily series use . Rates are official daily prints, not live market quotes, and come with a publication date — say so when it matters. Attribution when rates are shown publicly: "Rates by AllRatesToday" (https://allratestoday.com).
