About Swiss National Bank

The Swiss National Bank publishes official franc exchange rates through its data portal. The SNB publishes monthly averages (no daily official series exists), with history reaching back to 1914 — one of the longest official exchange rate records anywhere.

Node.js / TypeScript client

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

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

npm install snb-exchange-rate

import { getRate } from 'snb-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.

Why use the official Swiss National Bank rate?

A market rate is a moving target; the rate Swiss National Bank publishes is a fixed, citable figure that stays put once printed — which is why invoicing, customs, audit evidence, and statutory accounting in Switzerland lean on it rather than on a live feed. Every response from this API carries the bank's own rate_date, and on days with no publication you get the most recent published table — the one compliance rules tell 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 CHF) and marks it "derived": true — published and computed values are never silently mixed.

Endpoints

• GET /api/v1/central-bank/snb/latest — latest table or single pair (all plans)
• GET /api/v1/central-bank/snb/{YYYY-MM-DD} — the table for any date (paid plans)
• GET /api/v1/central-bank/snb/history — time series, up to 5,000 rows (paid plans)
• GET /api/v1/central-bank/snb/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 a month, so caching a published table locally makes a small quota go far.

Frequently asked questions

Does an exchange rate API exist for Swiss National Bank data?

Yes. This endpoint returns Swiss National Bank's official monthly average figures as JSON; the newest table is free on every plan.

How often are the rates updated?

Swiss National Bank publishes monthly averages — one averaged rate per calendar month, published once the month has closed; the API ingests each new table shortly after publication (latest: 2026-09-30).

Are these really Swiss National Bank's official figures?

Yes. Every value comes from Swiss National Bank's own publication and is served unmodified, carrying the bank's publication date; computed pairs are explicitly flagged derived.
