NBU Exchange Rates API — official hryvnia rates, history and invoice conversion

NBU Exchange Rates API returns the official National Bank of Ukraine exchange rates as flat JSON: any date, any range, any currency. Convert invoices to UAH on the invoice and payment dates and get the exchange difference (курсові різниці) ready for accounting.

What it does

• Rates - all currencies or a selected list for one date, many dates, or a long range (one currency = one request for the whole range).
• Convert - invoices with amount, currency, invoice date and payment date -> UAH on each date and exchange gain or loss.
• Monitor - get an alert when USD, EUR or any currency moves by a chosen percentage since the previous run.
• Official source only: bank.gov.ua, no scraping, no API key.

Who it's for

• Ukrainian sole proprietors (ФОП) and accountants
• ERP, billing and marketplace integrations
• Fintech and treasury dashboards
• Importers and exporters booking foreign currency invoices

Use with MCP, n8n, Make and Zapier

• Apify MCP server — add https://mcp.apify.com?tools=tiger19935/nbu-exchange-rates to Claude, Cursor or any MCP client so an AI agent can call this Actor as a tool.
• n8n / Make / Zapier — use the Apify integration, pick Run Actor, select tiger19935/nbu-exchange-rates and map the dataset items. Saved Tasks + a schedule turn it into a monitor with webhooks.

FAQ

Is it legal to use this data? The Actor only reads official open data from the National Bank of Ukraine (bank.gov.ua). NBU rates are public official data. Every row carries source and sourceUrl so you can attribute it. No captcha, login or personal data of private individuals is bypassed or collected.

How fresh is the data? Each row has dataAsOf - the publication date of the source file or API. If the publisher stops updating, dataAsOf stops moving and the daily self-test run fails, so you can tell stale data from a broken Actor.

What happens when nothing is found or the source is down? You get a not_found or source_error row and you are not charged. The Actor never fails silently with an empty dataset.

How do I get alerts? Create a Task with mode: monitor, schedule it (hourly or daily) and add a webhook, or connect the Apify integration in n8n, Make or Zapier. Only new, changed and removed records are returned and charged.

Why is there no rate for some dates? The NBU publishes rates for working days and announces rates for the following day; for dates it has not published yet you get a free not_found row.
