ECB Exchange Rates and Riksbank Policy Rate (EUR, SEK)

Official euro foreign exchange reference rates from the European Central Bank, daily or as monthly averages, for about 30 currencies. Get them as the ECB publishes them (units of a currency per 1 euro) or as Swedish krona cross rates, and add the ECB key interest rates and the Riksbank policy rate when you need them. One clean row per date and currency, with the source series and the license on every row.

Typical uses: converting invoices and ledgers at the official reference rate of a given day, monthly average rates for accounting and reporting, filling a currency table in an ERP or BI tool, and following when the ECB or the Riksbank changes its policy rate. The actor only delivers data. It gives no advice.

How the krona rates are calculated

The ECB quotes every currency against the euro. With base SEK the actor divides the two ECB rates of the same day: USD per SEK = (USD per EUR) / (SEK per EUR). Those rows have derived: true and both series keys in series. EUR per SEK is the inverse of the ECB's own SEK rate and is not marked as derived. Rates are rounded to six significant digits.

Cross rates calculated this way can differ slightly from the Riksbank's own SEK fixings, which are set at a different time of day. For monthly rows the krona rate is the ratio of the two ECB monthly averages.

Good to know

• Reference rates are not trading rates. The ECB sets them once a day around 14:10 CET and publishes them around 16:00 CET on TARGET business days. There are no rates on weekends and on TARGET holidays, so a run for a Saturday returns 0 exchange rate rows.
• Policy rates. The ECB series have a value for every calendar day. The Riksbank series has a value for every Swedish banking day. With monthly the actor returns the rate in force on the last day with a value in each month; for the current month that is the latest day so far.
• Why the Riksbank exchange rates are not used. The Riksbank API answers at most 5 calls per minute and 1 000 per day from one IP address without a personal key. Apify runs share IP addresses, so one call per currency would be throttled. The actor makes a single call to the Riksbank, for the policy rate, and takes all exchange rates from the ECB.
• Polite to the sources. One request to the ECB for all exchange rates, one for the ECB policy rates and one to the Riksbank. Each request is retried up to four times (2, 4, 8 and 16 seconds) on network errors, 429 and 5xx, since the ECB Data Portal answers 504 now and then. An answer in an unexpected format stops the run with a clear message instead of storing broken rows.
• Unknown currency codes stop the run with the list of valid codes.

Monitoring and scheduling

Set onlyNew to true to use the actor for a daily feed. The actor then remembers which rows it has delivered for the same input, in a named key-value store in your Apify account (nightwave-state-ecb-exchange-rates, one record per input). Each run returns and charges only rows that earlier runs did not deliver. The first run returns everything in the selection, and a run without news finishes successfully with 0 rows.

A row is identified by type, frequency, base, currency, series and date. Leave the dates empty so that every run covers the last week up to today. onlyNew and maxResults are not part of the remembered input, so you can change them without starting over. Changing any other field starts a fresh state. To start over with the same input, delete the record in the key-value store.

Example: a run every weekday at 16:30 Central European time that adds the day's krona rates and any policy rate change to your dataset. In Apify Console, open Schedules, create a schedule with the cron expression 30 16 * * 1-5, timezone Europe/Stockholm, and add this actor with the input below.

{
  "base": "SEK",
  "currencies": ["EUR", "USD", "GBP", "NOK", "DKK"],
  "includePolicyRates": true,
  "onlyNew": true,
  "maxResults": 100
}

The same schedule through the Apify API:

curl -X POST "https://api.apify.com/v2/schedules?token=<YOUR_TOKEN>" \
  -H "Content-Type: application/json" \
  -d '{"name": "daily-sek-rates", "cronExpression": "30 16 * * 1-5", "timezone": "Europe/Stockholm", "isEnabled": true, "isExclusive": true,
       "actions": [{"type": "RUN_ACTOR", "actorId": "nightwave-owner~ecb-exchange-rates",
                    "runInput": {"contentType": "application/json", "body": "{\"base\":\"SEK\",\"currencies\":[\"EUR\",\"USD\",\"GBP\",\"NOK\",\"DKK\"],\"includePolicyRates\":true,\"onlyNew\":true,\"maxResults\":100}"}}]}'

If you prefer a daily schedule, use 30 16 * * * instead. The ECB does not publish reference rates on weekends (or on TARGET holidays), so with onlyNew a daily run returns 0 new rows on Saturday and Sunday, and no rows are charged.

Data sources and licenses

• ECB Data Portal, https://data-api.ecb.europa.eu/service/data/EXR/... for the euro reference rates and .../FM/D.U2.EUR.4F.KR....LEV for the key ECB interest rates (API documentation). No key is needed. Under the ECB policy on the reuse of ESCB statistics, publicly available statistics may be reused free of charge, also commercially, provided the source is quoted ("Source: ECB statistics.") and the statistics are not modified. The krona cross rates are calculated by this actor, are marked with derived: true, and both original series are named on each row.
• Sveriges Riksbank SWEA API, https://api.riksbank.se/swea/v1/Observations/SECBREPOEFF/... for the policy rate (about the API). No key is needed. According to the Riksbank the data is free of charge and may be adapted and used without permission or agreement.

Every row carries source and license so you can credit the publisher. This actor is not affiliated with or endorsed by the European Central Bank or Sveriges Riksbank.

Pricing

Pay per result: 0.002 USD per row returned (event rate), which is 2.00 USD per 1 000 rows. Platform usage is included, so you pay only per result. maxResults caps how many rows a run returns, and so what a run can cost.

Rows are delivered only after they have been charged. If you set a maximum cost per run (maxTotalChargeUsd), the run stops there and its status message says how many rows were delivered.

På svenska

Actorn hämtar Europeiska centralbankens officiella referenskurser för euron, dagligen eller som månadsgenomsnitt, för ett 30-tal valutor. Välj bas EUR för kurserna som ECB publicerar dem, eller SEK för korskurser per svensk krona (inverseRate ger kronor per enhet, till exempel SEK per USD). Med includePolicyRates tillkommer ECB:s styrräntor (inlåningsränta, refiränta och utlåningsränta) och Riksbankens styrränta.

Exempel från en verklig körning: input och de första raderna i outputen finns i avsnittet Example from a real run ovan (körning sEQP32eEb9GBodcHz, 2026-10-04, 5 rader, 109 sekunder).

• Kronkurserna räknas fram ur två ECB-kurser samma dag och har derived: true. De kan skilja sig något från Riksbankens egna kurser, som sätts vid en annan tid på dagen.
• Riksbankens valutakurser används inte: utan personlig nyckel tillåter Riksbankens API 5 anrop per minut och 1 000 per dygn per IP-adress, och Apify-körningar delar IP-adresser. Actorn gör därför bara ett anrop till Riksbanken, för styrräntan.
• Tom input ger senaste veckans dagliga kurser för USD, SEK, GBP, NOK och DKK mot euro, 25 rader en vanlig vecka. maxResults är som standard 50.
• Med onlyNew: true levereras bara rader som tidigare körningar med samma input inte har levererat. Det passar för schemalagda körningar (se "Monitoring and scheduling").
• Källor: ECB Data Portal (fri återanvändning med källangivelse, "Source: ECB statistics.") och Riksbankens API (fritt att använda och bearbeta utan tillstånd). Endast data, inga råd.
• Pris: 0,002 USD per rad (2,00 USD per 1 000). Plattformsanvändningen ingår.
