# EUR-base reference rate history

`GET /api/v1/hnb/rates`

EUR-base daily reference rates since the first Eurozone business day (2023-01-02). Use the optional `valuta`, `from`, and `to` filters to slice the panel. Known upstream quirk: combining `valuta` with a date range collapses the upstream response to the current day only. Sugra applies a workaround by fetching the full panel for the range and filtering by currency client-side. Source: api.hnb.hr/tecajn-eur/v3.

## Query parameters

- `valuta` string, nullable — Optional ISO 4217 alphabetic code to filter by currency (case-insensitive).
- `from` string, nullable — Start date (YYYY-MM-DD). If omitted, upstream returns its default recent window.
- `to` string, nullable — End date (YYYY-MM-DD). If omitted, upstream returns its default recent window.

## Response `200`

Time series of EUR-base observations, 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.

- EnvelopeHnbEurHistoryPayload
  - `data` HnbEurHistoryPayload, required — Payload for /api/v1/hnb/rates (EUR-base history).
    - `items` HnbRateRow[], required — EUR-base observations since 2023-01-02, 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 the full 13-currency panel is 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.
  - `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.
