About Swiss Federal Office for Customs and Border Security

The Federal Office for Customs and Border Security (BAZG) sets the exchange rates that apply to Swiss customs declarations and import VAT. It publishes a rate each working morning that is legally valid for the following day — a Friday publication covers the weekend and Monday — which makes it the only daily official Swiss rate: the Swiss National Bank publishes monthly averages rather than a daily fixing.

Node.js / TypeScript client

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

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

const pair = await getRate('EUR', 'CHF', { 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: bazg-exchange-rate documentation.

Why use the official Swiss Federal Office for Customs and Border Security rate?

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

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

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.
