$ curl -s "https://open.er-api.com/v6/latest/USD" \
  | jq '{base: .base_code, time: .time_last_update_utc, rates: (.rates | {EUR, GBP, JPY, CHF, AUD})}'

1. [01] curlcurl -s "https://open.er-api.com/v6/latest/USD"
   Base = USD; returns ~170 rates. Updated daily. Swap `USD` for any ISO code (EUR, GBP, ...).
2. [02] jqjq '{base, time: .time_last_update_utc, rates: (.rates | {EUR, GBP, JPY, CHF, AU…
   Object construction: keep base + timestamp at the top, then project just the rates you care about. `(.rates | {EUR, ...})` is jq's shorthand for `{EUR: .rates.EUR, ...}`.
