Node.js / TypeScript client

A dedicated zero-dependency npm package wraps these endpoints — banguat-exchange-rate:

npm · banguat-exchange-rate GitHub · AllRates-Today/banguat-exchange-rate

npm install banguat-exchange-rate

import { getRate } from 'banguat-exchange-rate';

const pair = await getRate('USD', 'GTQ', { apiKey: 'art_live_...' });
console.log(pair.rate, pair.rate_date);

Zero dependencies, TypeScript types included, and it runs anywhere fetch exists — Node 18+, Bun, Deno, and edge runtimes.

Full reference — installation, all four functions, response shapes, error codes: banguat-exchange-rate documentation.

Why use the official Banco de Guatemala rate?

When an auditor or tax office in Guatemala asks which rate you used, "the GTQ mid-market rate at 14:32" is not an answer — the official rate published by Banco de Guatemala for that date is. This API returns exactly those published figures, stamped with the bank's own rate_date; on weekends and holidays the most recent published table is returned, as compliance rules expect.

Pairs the bank doesn't print directly are resolved from its table (inverse or cross via GTQ) and explicitly flagged "derived": true — so what the bank printed and what was computed are never confused.

Endpoints

• GET /api/v1/central-bank/banguat/latest — latest table or single pair (all plans)
• GET /api/v1/central-bank/banguat/{YYYY-MM-DD} — the table for any date (paid plans)
• GET /api/v1/central-bank/banguat/history — time series, up to 5,000 rows (paid plans)
• GET /api/v1/central-bank/banguat/availability — publication calendar: the dates the bank actually published (all plans)

Full parameter reference in the API documentation. Every request counts toward your plan's monthly quota — rates change once per business day, so caching a published table locally makes a small quota go far.
