      "Title": "feat(errors): unsupported_currency omits the 30 accepted ECB codes it just checked against",
      "Excerpt": "### Use case\n\n`unsupportedCurrency()` names the rejected currency code but never the ECB's accepted set, so a caller that guesses a currency outside ECB coverage (ARS, AED, RUB, TWD, VND are ordinary requests the ECB does not publish) has to spend a second `fx_list_currencies` call before it can correct or abandon the request. The live set is small — `GET https://api.frankfurter.dev/v1/currencies` returned exactly 30 codes on 2026-09-12 (`AUD BRL CAD CHF CNY CZK DKK EUR GBP HKD HUF IDR ILS INR…",

      "Excerpt": "### Use case\n\n`fx_get_rates` returns the provider's actual `rate_date`, but nothing in the response tells a caller whether a historical request landed on the date it asked for. `fx_get_rate` and `fx_convert_currency` already expose `date_snapped: boolean` plus an explicit weekend/holiday notice for exactly this. A caller building a multi-currency snapshot for a specific historical date (e.g. a month-end close) currently has to retain its own request date and diff it against `rate_date` to know…",
