# HRK legacy archive (pre-2023)

`GET /api/v1/hnb/legacy-hrk/rates`

Hrvatska kuna (HRK) base reference rates, frozen at 2022-12-31 when Croatia adopted the euro. Each daily list carries 15 entries (AUD, CAD, CZK, DKK, HUF, JPY, NOK, SEK, CHF, GBP, USD, XDR, BAM, EUR, PLN) quoted against HRK, with the `jedinica` field giving the quoting unit (HUF and JPY were historically quoted per 100). Dates from 2023-01-01 onward return an empty list. Source: api.hnb.hr/tecajn/v2.

## Query parameters

- `valuta` string, nullable — Optional ISO 4217 alphabetic code to filter by currency (case-insensitive). Covers 14 non-HRK currencies and XDR.
- `from` string, nullable — Start date (YYYY-MM-DD). Values on or after 2023-01-01 always resolve to an empty list.
- `to` string, nullable — End date (YYYY-MM-DD). Values after 2022-12-31 are capped server-side (HRK series ends there).

## Response `200`

Time series of HRK-base observations through 2022-12-31, sorted by ascending date then currency. The envelope `data_time` reflects the application date at 11:00 UTC, a stable convention - HNB publishes the list around midday CET with no sub-daily granularity.

- EnvelopeHnbLegacyHrkPayload
  - `data` HnbLegacyHrkPayload, required — Payload for /api/v1/hnb/legacy-hrk/rates (HRK pre-2023 archive).
    - `items` HnbRateRow[], required — HRK-base legacy observations through 2022-12-31, sorted by ascending date then currency.
      - `broj_tecajnice` string, nullable — Annual list sequence number (resets each January - not a stable monotonic ID).
      - `datum_primjene` string, nullable — Application date of the rate (YYYY-MM-DD). On HRK legacy this corresponds to the upstream `datum` field.
      - `valuta` string, nullable — Currency ISO 4217 alphabetic code (e.g. USD, GBP, JPY).
      - `sifra_valute` string, nullable — Currency ISO 4217 numeric code, zero-padded to three digits (e.g. 840 for USD).
      - `drzava` string, nullable — Country name as published by HNB, in Croatian (e.g. SAD = USA, Njemacka = Germany).
      - `drzava_iso` string, nullable — ISO 3166-1 alpha-3 country code. Present on the EUR-base list (v3); None on the HRK legacy list (v2).
      - `jedinica` integer, nullable — Quoting unit. Present on HRK legacy (1 or 100 - JPY and HUF historically quoted per 100 units). None on EUR-base (all currencies quoted per 1 EUR).
      - `kupovni_tecaj` number, nullable — Buy rate (bid) in units of the base currency. Croatian decimal comma parsed to float.
      - `srednji_tecaj` number, nullable — Middle rate (reference). Canonical value for analytical use and the Croatian-statutory accounting rate. Croatian decimal comma parsed to float.
      - `prodajni_tecaj` number, nullable — Sell rate (ask) in units of the base currency. Croatian decimal comma parsed to float.
    - `count` integer, required — Number of rows returned after client-side currency filter.
    - `currency_filter` string, nullable — The ISO 4217 code used to filter the response client-side, or null if all 15 legacy entries are returned.
    - `date_from` string, nullable — Start date of the requested range (YYYY-MM-DD) or null when unspecified.
    - `date_to` string, nullable — End date of the requested range (YYYY-MM-DD) or null when unspecified.
    - `archive_cutoff` string, required — The last day with HRK publications (2022-12-31). Dates at or after 2023-01-01 return an empty list.
  - `meta` SugraMeta, required — Metadata attached to every /api/v1/* response envelope.
    - `endpoint` string, required — Requested endpoint path.
    - `data_time` string, required — ISO 8601 UTC timestamp of the source data, not of the request.
    - `response_time` string, required — ISO 8601 UTC timestamp when this response was produced.
    - `provider` string, required — API name and version.
    - `source` string, nullable — Identifier of the primary upstream source used for this response.
    - `attribution` string, nullable — Human-readable attribution mandated by an upstream source (e.g. a securities regulator or self-regulatory organization). Present only on responses whose source requires the owner and source to be clearly identified. Do not remove or alter it when using the response.
    - `fallback_used` boolean, nullable — True when the primary source failed and a fallback produced the data.
    - `fallback_chain` string[], nullable — Ordered list of sources attempted, in the order they were tried.
    - `cached` boolean, nullable — True when this response was served from the internal cache.
    - `stale` boolean, nullable — True when the cached response was returned after the upstream rate-limited or errored. Clients can use this to detect degraded data.

## Other responses

- `401` — Missing or invalid `x-api-key` header. JSON body with a stable `code` distinguishing `missing_api_key` (no header sent) from `invalid_api_key` (header sent, key not accepted); any other 401 source carries the generic `unauthorized` with its detail as `reason`. Plus `hint`. `plan` is always null on 401 - an unauthenticated request has no plan; quota exhaustion is 429, not 401.
- `422` — Validation Error
- `429` — Daily rate limit exceeded. Check `X-RateLimit-Reset` for the next window.
- `503` — Upstream source is temporarily unavailable. Retry after a short delay.
