REST, JavaScript and Python examples." canonical: https://allratestoday.com/blog/erste-bank-serbia-exchange-rate-api/ source: AllRatesToday (https://allratestoday.com/) — Markdown mirror of the page above; index of all pages at https://allratestoday.com/llms.txt generated: 2026-11-15T19:13:45.196Z --- Erste Bank a.d. Novi Sad is the Serbian subsidiary of Austria’s Erste Group. Its kursna lista gives non-cash (devize) and cash (efektiva) buying and selling rates in dinars for 11 currencies. This guide shows how to read that board as JSON: what the rates mean, how they compare with the National Bank of Serbia official rate and with other banks in Serbia, and the calls that return them. ## What the Erste Srbija board shows - **11 currencies against the Serbian dinar**: AUD, CAD, CHF, CNY, DKK, EUR, GBP, JPY, NOK, SEK and USD. Every value is RSD per 1 unit of the foreign currency. - **The non-cash (devize) buy / sell pair.** Serbian banks publish a daily list with a non-cash (devizni) pair for transfers and accounts and a cash (efektiva) pair for notes, around the National Bank of Serbia’s middle rate. The rates here are the non-cash pair. The National Bank of Serbia official rate is shown next to each row. - **USD on 15 November 2026**: Erste Srbija bought at 102.09 and sold at 110.6 RSD, a spread of 8.00%. The National Bank of Serbia official rate was 106.35, so the bank's mid matched it. - **No timestamp on the bank's page.** Erste Srbija does not print a last-updated time, so `bank_updated_at` is `null` and `captured_at` (when AllRatesToday read the page) is the only time available. - **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 tightest spreads were EUR (4.00%), AUD (8.00%), CAD (8.00%) and the widest DKK (10.00%), CNY (10.00%), USD (8.00%). 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 Erste Srbija and other banks in Serbia USD on the 14 boards AllRatesToday reads in Serbia, all captured on 15 November 2026 (the National Bank of Serbia official rate was 106.35): | Bank | Buy | Sell | Spread | Mid vs official | | --- | --- | --- | --- | --- | | Banca Intesa (Serbia) | 101.03 | 111.66 | 10.00% | 0.00% | | Raiffeisen Bank Serbia | 101.03 | 111.56 | 9.90% | -0.05% | | UniCredit Bank Serbia | 103.16 | 109.54 | 6.00% | 0.00% | | AIK Banka | 103.16 | 109.54 | 6.00% | 0.00% | | OTP banka Srbija | 103.16 | 109.54 | 6.00% | 0.00% | | NLB Komercijalna banka | 101.14 | 111.56 | 9.80% | 0.00% | | Banka Poštanska štedionica | 103.16 | 109.54 | 6.00% | 0.00% | | **Erste Bank Serbia** | 102.09 | 110.6 | 8.00% | 0.00% | | ProCredit Bank Serbia | 98.3714 | 114.32 | 15.00% | 0.00% | | Addiko Bank Serbia | 101.03 | 111.66 | 10.00% | 0.00% | | Adriatic Bank | 104.22 | 108.47 | 4.00% | 0.00% | | API Bank | 104.33 | 108.37 | 3.80% | 0.00% | | Halkbank Serbia | 102.52 | 110.18 | 7.20% | 0.00% | | Yettel Bank | 102.63 | 110.07 | 7.00% | 0.00% | Erste Srbija had the 9th narrowest USD spread of the 14. One call to `/api/v1/bank-rates/rs` returns every board in the table at once. ## Get the board (REST) You need an API key; the [free key](https://allratestoday.com/register/) works.

The National Bank of Serbia rate is the one tax, accounting and customs rules in Serbia name; nobody transacts at it. Erste Srbija'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 Serbia endpoint](https://allratestoday.com/central-bank-rates-api/nbs/) when a rule asks for the official rate. ## FAQ ### Where do the Erste Bank Serbia rates come from? From the bank's own public rates page (https://www.erstebank.rs/sr/alati/kursna-lista), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price Erste Srbija shows, with the mid, the spread and the National Bank of Serbia rate added. ### Are these the official RSD exchange rates? No. They are Erste Srbija's retail prices for customers. The official rate in Serbia is the National Bank of Serbia 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 Erste Srbija board updated? AllRatesToday reads the page every hour. The bank prints no timestamp, so `captured_at` tells you when the rates were read. ### Can I get Erste Srbija 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. ## Erste Bank Serbia rates, as JSON Free API key, hourly board captures, the official rate alongside.
