Banco BISA is a large Bolivian private bank based in La Paz. Its home page lists its buying and selling prices for the US dollar and the euro. This guide shows how to read that board as JSON: what the rates mean, how they compare with the Banco Central de Bolivia official rate and with other banks in Bolivia, and the calls that return them.

## What the BISA board shows

- **2 currencies against the Bolivian boliviano**: EUR and USD. Every value is BOB per 1 unit of the foreign currency.
- **The buy / sell pair.** Bolivian banks print their own buying and selling price for the US dollar, usually next to the Banco Central de Bolivia rate. Bank prices can sit several percent either side of the central bank rate. The Banco Central de Bolivia official rate is shown next to each row.
- **USD on 15 November 2026**: BISA bought at 10.97 and sold at 11.9 BOB, a spread of 8.13%. The Banco Central de Bolivia official rate was 11.67, so the bank's mid sat -2.01% from it.
- **No timestamp on the bank's page.** BISA 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 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 USD 8.13%, EUR 14.83%. 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 BISA and other banks in Bolivia

USD on the 7 boards AllRatesToday reads in Bolivia, all captured on 15 November 2026 (the Banco Central de Bolivia official rate was 11.67):

| Bank | Buy | Sell | Spread | Mid vs official |
| --- | --- | --- | --- | --- |
| Banco Nacional de Bolivia | 11.17 | 11.97 | 6.91% | -0.86% |
| Banco de Crédito de Bolivia | 11.17 | 11.97 | 6.91% | -0.86% |
| **Banco BISA** | 10.97 | 11.9 | 8.13% | -2.01% |
| BancoSol | 10.5 | 11.92 | 12.67% | -3.94% |
| Banco Unión | 10.67 | 11.97 | 11.48% | -3.00% |
| Banco Económico | 10.67 | 12.02 | 11.90% | -2.79% |
| Banco Ganadero | 10 | 11.97 | 17.93% | -5.87% |

BISA had the 3rd narrowest USD spread of the 7. One call to `/api/v1/bank-rates/bo` 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 full board:

```
curl "https://allratestoday.com/api/v1/bank-rates/bo/bisabo" \
  -H "Authorization: Bearer art_live_your_key"
```

What comes back (the 15 November 2026 board, first three rows):

  -H "Authorization: Bearer art_live_your_key"

One currency over a date range, one row per day (paid plans; add `&format=csv`, `xml` or `xlsx` for a file):

```
curl "https://allratestoday.com/api/v1/bank-rates/bo/bisabo/history?ccy=USD&from=2026-11-15&to=2026-11-15" \

## JavaScript

```
npm install @allratestoday/sdk
```

```
import { AllRatesToday } from '@allratestoday/sdk';

const client = new AllRatesToday({ apiKey: 'art_live_your_key' });

// Banco BISA's USD row
const r = await client.bankRates('bo', { bank: 'bisabo', ccy: 'USD' });
console.log(`BISA buys USD at ${r.buy}, sells at ${r.sell} BOB`);

// The board as it stood on a past day
const past = await client.bankRates('bo', { bank: 'bisabo', date: '2026-11-15' });
console.log(past.snapshot_date, past.rates.length);
```

## Python

```
import requests

r = requests.get(
    "https://allratestoday.com/api/v1/bank-rates/bo/bisabo",
    headers={"Authorization": "Bearer art_live_your_key"},
    timeout=10,
)
r.raise_for_status()
for row in r.json()["rates"]:
    print(row["ccy"], row["buy"], row["sell"], row["spread_pct"])
```

## Board rate or official rate?

The Banco Central de Bolivia rate is the one tax, accounting and customs rules in Bolivia name; nobody transacts at it. BISA'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 [Banco Central de Bolivia endpoint](https://allratestoday.com/central-bank-rates-api/bcbol/) when a rule asks for the official rate.

## FAQ

### Where do the Banco BISA rates come from?

From the bank's own public rates page (https://www.bisa.com/), read hourly. AllRatesToday does not change the numbers: each row is the buy and sell price BISA shows, with the mid, the spread and the Banco Central de Bolivia rate added.

### Are these the official BOB exchange rates?

No. They are BISA's retail prices for customers. The official rate in Bolivia is the Banco Central de Bolivia 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 BISA 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 BISA 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.
