Banco Sol Exchange Rate API: AOA Buy and Sell Rates as JSON

Banco Sol is an Angolan commercial bank founded in 2001 with a large branch network in Luanda and the provinces. Its home page lists indicative buy and sell rates in kwanzas for the US dollar, euro, pound, rand and real. This guide shows how to read that board as JSON: what the rates mean, how they compare with the National Bank of Angola official rate and with other banks in Angola, and the calls that return them.

What the Banco Sol board shows

• 5 currencies against the Angolan kwanza: BRL, EUR, GBP, USD and ZAR. Every value is AOA per 1 unit of the foreign currency.
• The indicative exchange rates (compra / venda) pair. Angolan banks quote the kwanza with separate divisas (transfer) and notas (bank-note) columns, often at the same price. On 2026-11-13 the BAI dollar mid sat about 5% above the market rate. The National Bank of Angola official rate is shown next to each row.
• USD on 15 November 2026: Banco Sol bought at 913 and sold at 1049.95 AOA, a spread of 13.95%. The National Bank of Angola official rate was 913, so the bank's mid sat +7.50% from it.
• The bank's own timestamp. The page prints a last-updated stamp (2026-11-13 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 BRL (13.95%), EUR (13.95%), USD (13.95%) and the widest ZAR (13.95%), GBP (13.95%), USD (13.95%). 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 National Bank of Angola rate is the one tax, accounting and customs rules in Angola name; nobody transacts at it. Banco Sol'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 Angola endpoint when a rule asks for the official rate.

FAQ

Where do the Banco Sol rates come from?

From the bank's own public rates page (https://www.bancosol.ao/), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price Banco Sol shows, with the mid, the spread and the National Bank of Angola rate added.

Are these the official AOA exchange rates?

No. They are Banco Sol's retail prices for customers. The official rate in Angola is the National Bank of Angola 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 Banco Sol 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 Banco Sol 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.
