Node.js / TypeScript client

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

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

const pair = await getRate('AUD', 'USD', { 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 Reserve Bank of Australia rate?

When an auditor or tax office in Australia asks which rate you used, "the AUD mid-market rate at 14:32" is not an answer — the official rate published by Reserve Bank of Australia 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.

If a pair isn't in the bank's published table, the API computes it from that table (inverse or cross via AUD) 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.
