United Nations Federal Credit Union Exchange Rate API: USD Buy and Sell Rates as JSON

UNFCU is a credit union in Long Island City, New York, for staff of the United Nations and its agencies. Its exchange-rates page lists the US dollar price it pays and charges for 13 foreign currencies, for cash at its New York branches and for Digital Banking conversions. The page is updated Monday to Saturday at 15:00 UTC. This guide shows how to read that board as JSON: what the rates mean, how they compare with the Federal Reserve official rate and with other banks in the United States, and the calls that return them.

What the UNFCU board shows

• 13 currencies against the US dollar: AUD, CAD, CHF, DKK, EUR, GBP, HKD, JPY, KES, NOK, NZD, SEK and ZAR. Every value is USD per 1 unit of the foreign currency.
• The foreign cash at the new york branches and digital banking conversions, buy / sell pair. US banks do not post a transfer board: the rate on a wire is quoted per transaction. What they publish is the price of foreign bank notes, with spreads of around 10% between buying and selling. Tax and accounting use the official Federal Reserve, Treasury and IRS rates instead; the Federal Reserve’s official H.10 rate is shown next to each row.
• EUR on 15 November 2026: UNFCU bought at 1.0314 and sold at 1.1689 USD, a spread of 12.50%. The Federal Reserve official rate was 1.1154, so the bank's mid sat -1.37% from it.
• The bank's own timestamp. The page prints a last-updated stamp (15 November 2026 on the board above), returned as bank_updated_at next to our captured_at.
• Every day's board is kept permanently, from 14 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 tightest spreads were CAD (12.50%), EUR (12.50%), GBP (12.50%) and the widest KES (21.93%), ZAR (16.53%), NOK (14.73%). 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 Federal Reserve rate is the one tax, accounting and customs rules in the United States name; nobody transacts at it. UNFCU'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 Federal Reserve endpoint when a rule asks for the official rate.

FAQ

Where do the United Nations Federal Credit Union rates come from?

From the bank's own public rates page (https://www.unfcu.org/exchange-rates/), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price UNFCU shows, with the mid, the spread and the Federal Reserve rate added.

Are these the official USD exchange rates?

No. They are UNFCU's retail prices for customers. The official rate in the United States is the Federal Reserve 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 UNFCU 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 UNFCU rates for a past date?

Yes, from 14 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=EUR&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.
