CNB Exchange Rates
FinanceThe Czech National Bank publishes koruna exchange rates, PRIBOR and CZEONIA money market rates, and FX forward points through an open API. Agents pull daily, monthly, and average rate series with no account or key required.
What This Integration Enables
Most currency APIs sell you a market rate. The Czech National Bank publishes something narrower and more useful: the official koruna rate list that Czech accounting, tax filing, and statutory reporting are measured against. That distinction is the whole reason to build on this connector rather than a market feed. When an auditor asks where a revaluation figure came from, the answer you want is the central bank's published list for a named day, not a vendor's snapshot of a trading venue.
FlowRunner agents read the daily list of roughly thirty currencies, the separate monthly list of roughly one hundred and thirty, and the three average series that Czech practice actually uses: monthly for a month of transactions, cumulative for a year to date figure, quarterly for quarterly reporting. The same connectors layer reaches PRIBOR and CZEONIA for loan repricing, open market operations, FX forward points, and short term securities settlement. The API is open, so there is no key to rotate and no account to provision. What the connector adds is the arithmetic discipline the raw feed does not: Convert Amount reads the rate, divides by the amount the rate is quoted per, and reports the rate, the unit, and the effective date it used.

Use Case Scenarios
-
Month end revaluation that survives an audit
At close, an agent lists every open foreign currency balance from the ledger in NetSuite or Xero, then calls Convert Amount once per currency against the closing date. Each result comes back with the published rate, the unit that rate is quoted per, and the validFor date, and all three are written next to the revalued figure in a Google Sheets tab. Nobody has to remember that the afghani row is quoted per one hundred, because the connector already divided. The revaluation pack that reaches the auditor shows its own source for every line.
-
Year to date reporting without a manual extract
A reporting flow calls Get Cumulative Averages For Currency for the currencies the group trades in, plus Get Monthly Averages For Year for the full grid. The averages land in BigQuery beside the transaction data, so the finance team can pivot a year of foreign currency activity against the exact average series a Czech return expects. Get Quarterly Averages For Year covers the quarterly filings from the same job. What used to be a quarterly download and reshape becomes a table that is already current.

Watching a floating rate loan reprice
A treasury agent calls Get PRIBOR For Term on a schedule for the term the group's facility reprices on, and compares the published fixing against the covenant thresholds held in Airtable. Get Daily CZEONIA adds the traded overnight rate and the volume behind it, which is a different signal from a quoted one. When a fixing moves through a threshold, the agent posts the fixing, the term, and the affected facilities into Slack so treasury sees the repricing before the interest run does.
Human-in-Loop Highlight
The bank does not fail a request for a day it has not published. Ask for a Sunday, a Czech public holiday, or today before 14:30 Prague time, and the API returns the last valid list instead of an error. That behavior is convenient for a dashboard and dangerous for a close, because a revaluation posted against Friday's list and dated Sunday is a wrong number that no status code will ever flag. So the close agent compares the validFor field on the rows against the date it was asked to book, and when they disagree it stops. It posts: "Requested closing date 2026-06-30 is a Sunday. The most recent published central list is validFor 2026-06-27. Book the revaluation at the 27 June list, or hold the close until the next publication?" The controller answers, because that figure goes into a statutory filing and the choice belongs to the person who signs it.
