REST, JavaScript and Python examples." canonical: https://allratestoday.com/blog/apb-agricultural-promotion-bank-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: 2026-11-15T19:13:52.022Z --- Agricultural Promotion Bank (APB) is a Lao state-owned bank focused on rural and agricultural lending. Its exchange page lists buying and selling rates in kip for five currencies. This guide shows how to read that board as JSON: what the rates mean, how they compare with the Bank of the Lao PDR official rate and with other banks in Laos, and the calls that return them. ## What the APB board shows - **5 currencies against the Laotian kip**: CNY, EUR, THB, USD and VND. Every value is LAK per 1 unit of the foreign currency. - **The counter board pair.** Lao banks print separate buying rates for notes, bills and electronic transfers against one selling rate, set each morning around the Bank of the Lao PDR reference rate. The rates here are the electronic-transfer buy against the sell. The Bank of the Lao PDR official rate is shown next to each row. - **USD on 15 November 2026**: APB bought at 22394 and sold at 22632 LAK, a spread of 1.06%. The Bank of the Lao PDR official rate was 22630, so the bank's mid sat -0.52% from it. - **The bank's own timestamp.** The page prints a last-updated stamp (`13/11/2026` 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 tightest spreads were USD (1.06%), THB (1.56%), EUR (1.82%) and the widest VND (3.55%), CNY (1.97%), EUR (1.82%). 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 APB and other banks in Laos USD on the 7 boards AllRatesToday reads in Laos, all captured on 15 November 2026 (the Bank of the Lao PDR official rate was 22630): | Bank | Buy | Sell | Spread | Mid vs official | | --- | --- | --- | --- | --- | | BCEL (Banque pour le Commerce Extérieur Lao) | 22291 | 22631 | 1.51% | -0.75% | | Lao-Viet Bank | 22302 | 22632 | 1.47% | -0.72% | | JDB (Joint Development Bank) | 22371 | 22629 | 1.15% | -0.57% | | ACLEDA Bank Lao | 22504 | 22631 | 0.56% | -0.28% | | KBank Laos (Kasikornthai Bank) | 22319 | 22632 | 1.39% | -0.68% | | **APB (Agricultural Promotion Bank)** | 22394 | 22632 | 1.06% | -0.52% | | BIC Bank Lao | 22396 | 22609 | 0.95% | -0.56% | APB had the 3rd narrowest USD spread of the 7. One call to `/api/v1/bank-rates/la` 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 Bank of the Lao PDR rate is the one tax, accounting and customs rules in Laos name; nobody transacts at it. APB'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 the Lao PDR endpoint](https://allratestoday.com/central-bank-rates-api/bol/) when a rule asks for the official rate. ## FAQ ### Where do the APB (Agricultural Promotion Bank) rates come from? From the bank's own public rates page (https://www.apb.com.la/exchange), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price APB shows, with the mid, the spread and the Bank of the Lao PDR rate added. ### Are these the official LAK exchange rates? No. They are APB's retail prices for customers. The official rate in Laos is the Bank of the Lao PDR 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 APB 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 APB 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. ## APB (Agricultural Promotion Bank) rates, as JSON Free API key, hourly board captures, the official rate alongside.
