Node.js / TypeScript client
A dedicated zero-dependency npm package wraps these endpoints — 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.
Full reference — installation, all four functions, response shapes, error codes: snb-exchange-rate documentation.
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.
