Node.js / TypeScript client

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

npm install nbc-cambodia-exchange-rate
import { getRate } from 'nbc-cambodia-exchange-rate';

const pair = await getRate('USD', 'KHR', { 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.

Why use the official National Bank of Cambodia rate?

Live market rates move continuously, but tax filings, customs declarations, audits, and statutory accounting in Cambodia and beyond typically require the official rate published by National Bank of Cambodia for a given date — a fixed, citable number that never changes after publication. This API serves those published tables with the bank's own rate_date on every response; weekends and holidays return the most recent published date, which is the rate compliance rules require you to apply.

If a pair isn't in the bank's published table, the API computes it from that table (inverse or cross via KHR) and marks it "derived": true — published and computed values are never silently mixed.

Endpoints

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.
