Sveriges Riksbank Exchange Rates API — riksbank-exchange-rate

Official Sveriges Riksbank (Sweden) daily exchange rates for Node.js and TypeScript. The published central bank rates behind tax filings, customs valuations, audits, and compliant invoicing — not market estimates, but the numbers Sveriges Riksbank itself prints, every business day.

🚀 Why this client?

• 🏛️ Official published rates — Sveriges Riksbank's own table, with the publisher's own rate_date on every response
• 📅 History back to 2016 — point-in-time tables and daily series for any past date
• 🔀 Published vs derived, always flagged — computed inverse/cross pairs carry derived: true, never mixed with official prints
• ⚡ Zero dependencies — pure ESM + CJS over global fetch; Node 18+, Bun, Deno, and edge runtimes
• 🔷 Type-safe — full TypeScript definitions shipped with the package
• 🧾 Compliance-grade metadata — rate_type, publication date, and source disclaimer on every response

Official rate, not mid-market: every value here is a number Sveriges Riksbank itself published, fixed once printed and carrying the central bank's own rate_date — what filings and audits require. Need the live mid-market rate for pricing or display instead? Use the mid-market API or @allratestoday/sdk. The two can diverge by several percent.

📈 Latest published table

The image is rendered live from the keyless endpoint, so it follows the central bank's publications on npm and on GitHub alike without a new release. The same table as text is folded below for search and copy-paste: on GitHub a daily Action refreshes it whenever the central bank publishes a new table; on npm it is as of the package's publish date.

---

Latest pair rate

Free plan and up. Pairs the central bank does not print directly are resolved from its table and flagged (see Published vs derived rates below).

const pair = await getRate('EUR', 'SEK', { apiKey: 'art_live_...' });

Response:

{
  bank: 'riksbank',
  name: 'Sveriges Riksbank',
  rate_date: '2026-10-13',   // Sveriges Riksbank's own publication date
  source: 'EUR',
  target: 'SEK',
  rate: 11.1698,
  rate_type: 'middle',
  derived: false,
  method: 'published',
  disclaimer: 'Official rates as published by the named central bank. On weekends/holidays the most recent published rate_date is returned.'
}

Full published table

Free plan and up. The complete table for the latest publication date.

import { getLatestRates } from 'riksbank-exchange-rate';

const table = await getLatestRates({ apiKey: 'art_live_...' });
console.log(table.rate_date, table.rates.length);

Response:

{
  bank: 'riksbank',
  name: 'Sveriges Riksbank',
  rate_date: '2026-10-13',
  rates: [
    { "base": "EUR", "quote": "SEK", "type": "middle", "value": 11.1698 },
    // … the rest of the published table (29 currencies vs SEK)
  ],
  disclaimer: '…'
}

Table for a date

Paid plans. The official table for any date since 2016 — weekends and holidays return the most recent published date, flagged via published_on_requested_date, which is exactly the in-force rate a filing needs.

import { getRatesForDate } from 'riksbank-exchange-rate';

const day = await getRatesForDate('2026-06-30', { apiKey: 'art_live_...' });
// Optionally narrow to one pair:
const one = await getRatesForDate('2026-06-30', { apiKey: 'art_live_...', source: 'EUR', target: 'SEK' });

Response:

{
  bank: 'riksbank',
  requested_date: '2026-06-30',
  rate_date: '2026-06-30',                // the date actually published
  published_on_requested_date: true,      // false when a weekend/holiday fell back
  rates: [ /* the full table for that date */ ],
  disclaimer: '…'
}

Daily time series

Paid plans. One resolved rate per publication date — ready for charting, revaluation runs, or audit workpapers.

import { getHistory } from 'riksbank-exchange-rate';

const series = await getHistory(
  { source: 'EUR', target: 'SEK', from: '2026-01-01', to: '2026-10-13' },
  { apiKey: 'art_live_...' }
);

Response:

{
  bank: 'riksbank',
  source: 'EUR',
  target: 'SEK',
  from: '2026-01-01',
  to: '2026-10-13',
  count: 152,
  rates: [
    // one entry per publication date
    { date: '2026-10-13', rate: 11.1698, rate_type: 'middle', derived: false, method: 'published' },
    // …
  ],
  disclaimer: '…'
}

Pass { symbol: 'EUR' } instead of source/target to get the raw published rows for one currency (all rate types, no pair resolution).

🗺️ Currencies covered

Sveriges Riksbank currently publishes rates covering 29 currencies against the SEK (as of the latest table):

🇦🇺 AUD · 🇧🇷 BRL · 🇨🇦 CAD · 🇨🇭 CHF · 🇨🇳 CNY · 🇨🇿 CZK · 🇩🇰 DKK · 🇪🇺 EUR · 🇬🇧 GBP · 🇭🇰 HKD · 🇭🇺 HUF · 🇮🇩 IDR · 🇮🇱 ILS · 🇮🇳 INR · 🇮🇸 ISK · 🇯🇵 JPY · 🇰🇷 KRW · 🇲🇽 MXN · 🇲🇾 MYR · 🇳🇴 NOK · 🇳🇿 NZD · 🇵🇭 PHP · 🇵🇱 PLN · 🇷🇴 RON · 🇸🇬 SGD · 🇹🇭 THB · 🇹🇷 TRY · 🇺🇸 USD · 🇿🇦 ZAR

🏛️ Source

Sveriges Riksbank, founded in 1668, is the world's oldest central bank. It publishes daily middle rates for the krona against around 30 currencies each banking day.

• Publisher's own page: Interest and exchange rates search · www.riksbank.se
• Publication: every business day; the exact schedule, freshness status and any current delay are on the Sveriges Riksbank rates page
• In the API: usually by 16:20 UTC (measured over the last 10 publications). Schedule a sync at or after that time and retry hourly until rate_date moves; every response carries the same figure as available_by_utc — see when to poll
• Values are stored unmodified, with the publisher's own rate_date on every row — see the methodology

🧭 Reading the numbers

• value is always quote currency per 1 unit of base currency (base: "EUR", quote: "USD", value: 1.15 means 1 EUR = 1.15 USD).
• Sveriges Riksbank quotes SEK per 1 unit of foreign currency (e.g. base: "USD", quote: "SEK" means SEK per one US dollar).
• Need the other way round? Ask getRate(target, source) and the API inverts or crosses for you, flagged derived: true — never divide a published rate yourself in a compliance workflow.
• rate_type tells you which of the central bank's series a row belongs to (middle here); some publishers print buy/sell or several fixings for the same pair.

🧩 ERP & accounting systems

Loading the official Sveriges Riksbank rate into an accounting system is a supported workflow, not a hack. Step-by-step guides with the direction each system expects:

• Dynamics 365 Business Central — built-in Currency Exchange Rate Service, no code
• Xero · QuickBooks Online · SAP S/4HANA and ECC · Odoo

The same keyed endpoints return ?format=csv, ?format=xml and ?format=xlsx, and accept the key as ?api_key= on the URL for importers that cannot send headers:

curl "https://allratestoday.com/api/v1/central-bank/riksbank/latest?format=xml&api_key=art_live_..."

🤖 AI agents

• MCP server: npx -y @allratestoday/central-bank-mcp (stdio) or the hosted endpoint https://allratestoday.com/api/mcp — tools for official rates, history, cross-bank comparison and publication calendars
• Already using the general SDK or MCP server? Since 2026-10-01 @allratestoday/sdk 1.4+ has officialRates('riksbank') and @allratestoday/mcp-server 0.6+ has a get_official_rates tool — both return this source's latest table with no key, so you can add it without a second dependency
• Claude Code plugin (no key): /plugin marketplace add AllRates-Today/claude-code-plugin then /plugin install allratestoday@allratestoday — bundles both MCP servers plus an /official-rate riksbank ... command
• Evaluating? Agents can self-issue a trial key with no signup: POST https://allratestoday.com/api/agent/keys (send Content-Type: application/json) returns a 100-call key valid 7 days that covers the free-plan methods (latest table, pairs); dated tables and history need a paid plan. The MCP servers expose it as request_trial_key

⚖️ Published vs derived rates

If Sveriges Riksbank does not print a pair directly, the API resolves it from the central bank's own table and says so — official and computed values are never confused:

method	derived	Meaning
published	false	The central bank printed this pair directly
inverse	true	Computed as 1 ÷ the published opposite direction
cross	true	Computed via SEK from two published rates

🛡️ Error handling

Errors are thrown as Error with status (HTTP code) and body (the API's JSON error) attached:

try {
  const pair = await getRate('EUR', 'XXX', { apiKey: 'art_live_...' });
} catch (err) {
  console.log(err.message); // human-readable reason
  console.log(err.status);  // e.g. 404
}

Status	Meaning
—	Missing apiKey (thrown before any request)
400	Malformed date or parameters
401	Invalid API key
403	Endpoint needs a paid plan (historical dates & series)
404	Pair or date range not covered by Sveriges Riksbank
429	Monthly quota exceeded

🔷 TypeScript

Full definitions ship with the package — no @types install:

import type { LatestRates, PairRate, DatedRates, RateEntry, HistoryQuery, RequestOptions } from 'riksbank-exchange-rate';

📦 CommonJS

const { getRate } = require('riksbank-exchange-rate');

getRate('EUR', 'SEK', { apiKey: 'art_live_...' }).then((pair) => console.log(pair.rate));

💡 Quota tips

• Rates change once per business day — cache the published table locally and a small monthly quota goes a long way.
• Every request counts toward your AllRatesToday quota, shared across all AllRatesToday endpoints on your key.
