Comerțbank Exchange Rate API: MDL Buy and Sell Rates as JSON

Comerțbank is a Chișinău-based commercial bank, formerly BCR Chișinău. Its home page lists dated buy and sell rates in lei for the euro, US dollar and Romanian leu. This guide shows how to read that board as JSON: what the rates mean, how they compare with the National Bank of Moldova official rate and with other banks in Moldova, and the calls that return them.

What the Comerțbank board shows

• 3 currencies against the Moldovan leu: EUR, RON and USD. Every value is MDL per 1 unit of the foreign currency.
• The branch buy / sell pair. Moldovan banks publish short boards, usually the euro, US dollar and a few neighbouring currencies, with separate rates for cash at the counter and for card operations, quoted in lei per unit. The National Bank of Moldova official rate is shown next to each row.
• USD on 15 November 2026: Comerțbank bought at 18 and sold at 18.15 MDL, a spread of 0.83%. The National Bank of Moldova official rate was 18.1762, so the bank's mid sat -0.56% from it.
• The bank's own timestamp. The page prints a last-updated stamp (2026-11-15 on the board above), returned as bank_updated_at next to our captured_at.
• Every day's board is kept permanently, from 15 November 2026, the day collection started. 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 spreads were EUR 0.55%, USD 0.83%, RON 1.33%. 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.

USD at Comerțbank and other banks in Moldova

USD on the 8 boards AllRatesToday reads in Moldova, all captured on 15 November 2026 (the National Bank of Moldova official rate was 18.1762):

Comerțbank had the narrowest USD spread of the 8. One call to /api/v1/bank-rates/md returns every board in the table at once.

Board rate or official rate?

The National Bank of Moldova rate is the one tax, accounting and customs rules in Moldova name; nobody transacts at it. Comerțbank'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 National Bank of Moldova endpoint when a rule asks for the official rate.

FAQ

Where do the Comerțbank rates come from?

From the bank's own public rates page (https://comertbank.md/), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price Comerțbank shows, with the mid, the spread and the National Bank of Moldova rate added.

Are these the official MDL exchange rates?

No. They are Comerțbank's retail prices for customers. The official rate in Moldova is the National Bank of Moldova 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 Comerțbank 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 Comerțbank rates for a past date?

Yes, from 15 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.
