Every plan. - `GET /api/v1/bank-rates/ca/bmo/history?ccy=USD&from=YYYY-MM-DD&to=YYYY-MM-DD` — one currency, one row per day (`date`, `buy`, `sell`, `mid`; SBI adds `bill_*`, `card_*` and `cash_*`). Defaults to the last year; `&format=csv`, `xml` or `xlsx`. Paid plans, one call per month covered. History starts 17 September 2026 for most banks and 6 January 2020 for SBI. ## Response fields | Field | Meaning | | --- | --- | | `quote_ccy` | CAD. Every price is CAD per 1 unit of `ccy`. | | `buy` | What the bank pays you in CAD for one unit of foreign currency. | | `sell` | What the bank charges you in CAD for one unit — the rate for sending money abroad. | | `mid`, `spread_pct` | Midpoint of buy and sell; spread = (sell − buy) ÷ mid, in percent. | | `official`, `vs_official_pct` | The Bank of Canada rate for the same currency and how far the bank’s mid sits from it. | | `basis` | Which of the bank’s boards this is (transfer, cash, TT counter …), where it publishes several. | | `captured_at` | When AllRatesToday read the bank’s page (UTC). Boards are read hourly. | | `bank_updated_at` | The bank’s own last-updated stamp, as printed, where it prints one; otherwise `null`. | ## Errors and limits - `401` — no key or an invalid key. Any plan’s key works, the free one included. - `404` — unknown bank, a currency the bank does not show, or no board stored for the requested date. - `400` — `date` not in `YYYY-MM-DD` form, or in the future. - Each call counts against your plan. Responses can be cached for five minutes; past-day boards never change. - Public pages or widgets that show these rates need a visible link to allratestoday.com. ## Why use bank board rates through an API? The Bank of Canada official rate is what accounting, tax and customs rules name, but it is not what a customer pays at the counter or in an app. Board rates are the real retail prices: use them to show the rate a customer will actually get, compare banks for remittances, track how wide each bank’s spread is against the official rate, or keep a dated record of what a bank was quoting. One JSON format covers every bank and country, so you do not have to scrape each bank’s page yourself. ## Start calling the BMO Bank of Montreal board API Free key, JSON responses, hourly board captures with the official rate alongside.

No. BMO Bank of Montreal sets its own buying and selling rates and changes them through the day. The official rate is published once per business day by the Bank of Canada; it is shown in the Official column and is the figure accounting, tax and customs rules refer to. ### Which BMO Bank of Montreal rate applies when I send money abroad? The sell rate: you are buying foreign currency from the bank. When you convert foreign currency into CAD, the buy rate applies. Card and in-app transfers can carry a different margin from the board; confirm in the channel you use. ### How current is this table? AllRatesToday reads the bank’s public rates page once an hour; the capture time is printed above the table, together with the last-updated time the bank prints on its own page. Rates may have changed since. ## Compare [All Canada banks side by sideBest buy and sell per currency](https://allratestoday.com/bank-exchange-rate-api/ca/) [RBC Royal BankBoard rates](https://allratestoday.com/bank-exchange-rate-api/ca/rbc/)[ScotiabankBoard rates](https://allratestoday.com/bank-exchange-rate-api/ca/scotiabank/)[TD Canada TrustBoard rates](https://allratestoday.com/bank-exchange-rate-api/ca/td/) [Bank of CanadaOfficial rate, daily, with history](https://allratestoday.com/central-bank-rates-api/boc/)
