By [Madhushan](https://allratestoday.com/authors/madhushan/), Founder & Lead Developer · Updated 15 Nov 2026 **Retail board rates.** These are the prices 3 Banka displayed on [its own rates page](https://www.3bank.rs/) when we last read it. They are indicative, change through the day, and are not official rates. For the reference rate, see the [National Bank of Serbia](https://allratestoday.com/central-bank-rates-api/nbs/). ![](https://allratestoday.com/logos/banks/trecabankars.webp) ## About 3 Banka [www.3bank.rs](https://www.3bank.rs/) 3 Banka is a Serbian bank based in Novi Sad (formerly Opportunity banka). Its home page lists the euro’s non-cash and cash buy and sell rates in dinars. ## ![](https://flagcdn.com/24x18/rs.png) Latest board, read 15 Nov 2026, 19:31 Serbia time (1h ago) Bank’s own last-updated stamp: **2026-11-13** (as printed on its page, local time). Board shown: **Devize (non-cash) buy / sell**. Banks outside the Gulf publish several boards for the same currency — counter notes, drafts, transfers, cards — and this page shows one of them, the same one for every bank in Serbia so the comparison is like for like. The others are on the bank’s own page. | Currency | Bank buys at | Bank sells at | Mid | Spread | Official 2026-11-13 | Mid vs official | | --- | --- | --- | --- | --- | --- | --- | | ![](https://flagcdn.com/24x18/eu.png)`EUR` | 116.15 | 119.09 | 117.62 | 2.50% | 117.62 | 0.00% | All values are RSD per 1 unit of the currency. Spread = (sell − buy) ÷ mid. Average spread across the board: **2.50%**.

Every plan. - `GET /api/v1/bank-rates/rs/trecabankars/history?ccy=EUR&from=YYYY-MM-DD&to=YYYY-MM-DD` — one currency, one row per day (`date`, `buy`, `sell`, `mid`; SBI adds `bill_*`, `card_*` and `cash_*`).

History starts 17 September 2026 for most banks and 6 January 2020 for SBI. ## Response fields | Field | Meaning | | --- | --- | | `quote_ccy` | RSD. Every price is RSD per 1 unit of `ccy`. | | `buy` | What the bank pays you in RSD for one unit of foreign currency. | | `sell` | What the bank charges you in RSD 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 National Bank of Serbia 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 National Bank of Serbia 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 3 Banka board API Free key, JSON responses, hourly board captures with the official rate alongside.

Machine-readable copy: Markdown [https://allratestoday.com/bank-exchange-rate-api/rs/trecabankars.md](https://allratestoday.com/bank-exchange-rate-api/rs/trecabankars.md). JSON needs an API key: `https://allratestoday.com/api/v1/bank-rates/rs/trecabankars`. ## Frequently asked questions ### Is the 3 Banka rate the official Serbia exchange rate? No. 3 Banka sets its own buying and selling rates and changes them through the day. The official rate is published once per business day by the National Bank of Serbia; it is shown in the Official column and is the figure accounting, tax and customs rules refer to. ### Which 3 Banka rate applies when I send money abroad? The sell rate: you are buying foreign currency from the bank. When you convert foreign currency into RSD, 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. ### Do you have historical 3 Banka rates? Yes, from 13 Nov 2026 onwards, one board per day. One day: /api/v1/bank-rates/rs/trecabankars?date=YYYY-MM-DD (every plan). A range: /api/v1/bank-rates/rs/trecabankars/history?ccy=USD (paid plans). ## Compare [All Serbia banks side by sideBest buy and sell per currency](https://allratestoday.com/bank-exchange-rate-api/rs/) [3 Banka exchange rate API guideBoard, spreads, peers and code examples](https://allratestoday.com/blog/3-banka-exchange-rate-api/) [Banca Intesa (Serbia)Board rates](https://allratestoday.com/bank-exchange-rate-api/rs/intesars/)[Raiffeisen Bank SerbiaBoard rates](https://allratestoday.com/bank-exchange-rate-api/rs/raiffeisenrs/)[UniCredit Bank SerbiaBoard rates](https://allratestoday.com/bank-exchange-rate-api/rs/unicreditrs/)[AIK BankaBoard rates](https://allratestoday.com/bank-exchange-rate-api/rs/aikbank/)[OTP banka SrbijaBoard rates](https://allratestoday.com/bank-exchange-rate-api/rs/otprs/)[NLB Komercijalna bankaBoard rates](https://allratestoday.com/bank-exchange-rate-api/rs/nlbkb/)[Banka Poštanska štedionicaBoard rates](https://allratestoday.com/bank-exchange-rate-api/rs/postanska/)[Erste Bank SerbiaBoard rates](https://allratestoday.com/bank-exchange-rate-api/rs/ersters/)[ProCredit Bank SerbiaBoard rates](https://allratestoday.com/bank-exchange-rate-api/rs/procreditrs/)[Addiko Bank SerbiaBoard rates](https://allratestoday.com/bank-exchange-rate-api/rs/addikors/)[Adriatic BankBoard rates](https://allratestoday.com/bank-exchange-rate-api/rs/adriaticrs/)[API BankBoard rates](https://allratestoday.com/bank-exchange-rate-api/rs/apibankrs/)[Halkbank SerbiaBoard rates](https://allratestoday.com/bank-exchange-rate-api/rs/halkbankrs/)[Yettel BankBoard rates](https://allratestoday.com/bank-exchange-rate-api/rs/yettelrs/) [National Bank of SerbiaOfficial rate, daily, with history](https://allratestoday.com/central-bank-rates-api/nbs/)
