Assiniboine Credit Union Exchange Rate API: CAD Buy and Sell Rates as JSON

Assiniboine Credit Union is a Manitoba credit union based in Winnipeg, now including the former Westoba and Entegra credit unions. Its rates page lists daily US dollar buy and sell rates by amount tier. This guide shows how to read that board as JSON: what the rates mean, how they compare with the Bank of Canada official rate and with other banks in Canada, and the calls that return them.

What the Assiniboine CU board shows

• 1 currency against the Canadian dollar: USD. Every value is CAD per 1 unit of the foreign currency.
• The US dollar buy / sell (first tier, us$0 to us$24,999) pair. Canadian banks post buy and sell prices in Canadian dollars per unit of foreign currency, usually separate for cash and for non-cash transfers and drafts, and tiered by amount. The Bank of Canada publishes one daily average rate per currency, which sits between the banks' buying and selling prices. The Bank of Canada official rate is shown next to each row.
• USD on 15 November 2026: Assiniboine CU bought at 1.4056 and sold at 1.4456 CAD, a spread of 2.81%. The Bank of Canada official rate was 1.4257, so the bank's mid sat -0.01% from it.
• The bank's own timestamp. The page prints a last-updated stamp (November 13, 2026 on the board above), returned as bank_updated_at next to our captured_at.
• Every day's board is kept permanently, from 13 November 2026. Read one past day with ?date=, or a range for one currency with the /history endpoint (paid plans).

Spreads across the board

On the 15 November 2026 board the spread was USD 2.81%. Spread is (sell − buy) ÷ mid: what a round trip through the bank costs, before any fees. The API returns it on every row as spread_pct, so you can rank currencies or alert when a bank widens its board.

Board rate or official rate?

The Bank of Canada rate is the one tax, accounting and customs rules in Canada name; nobody transacts at it. Assiniboine CU's board is the price a customer actually gets. The API puts both on every row: official is the central bank's rate for the same currency and vs_official_pct is how far the bank's mid sits from it. Use the board to show customers a real price, compare banks for a remittance, or keep a dated record of what the bank quoted; use the Bank of Canada endpoint when a rule asks for the official rate.

FAQ

Where do the Assiniboine Credit Union rates come from?

From the bank's own public rates page (https://www.acu.ca/rates), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price Assiniboine CU shows, with the mid, the spread and the Bank of Canada rate added.

Are these the official CAD exchange rates?

No. They are Assiniboine CU's retail prices for customers. The official rate in Canada is the Bank of Canada rate, which the API returns as official on each row where the central bank has one, and in full from the central-bank endpoint.

How often is the Assiniboine CU board updated?

AllRatesToday reads the page every hour. The bank's own last-updated stamp is returned as bank_updated_at, so you can tell a fresh read of an unchanged board from a new board.

Can I get Assiniboine CU rates for a past date?

Yes, from 13 November 2026 onward; every day's board is kept permanently. Add ?date=YYYY-MM-DD for one day: the response is the board captured that day, or the nearest earlier day within five days, with date_requested and snapshot_date added. For a range, /history?ccy=USD&from=…&to=… returns one row per day as JSON, CSV, XML or XLSX on paid plans.

Do I need an API key?

Yes. Commercial bank boards need an API key; any plan works, the free key included, and each call counts against the plan. Public pages or widgets that show the rates need a visible link to allratestoday.com.
