Migrating from v1

The v1 API will remain available at /v1/ endpoints. To migrate to /v2:

• Change your base URL from /v1/latest to /v2/rates.
• Update response parsing: rates are now an array of {"date", "base", "quote", "rate"} objects instead of {"base", "date", "rates": {"USD": 1.23}}.
• The symbols parameter is renamed to quotes.
• The from and to parameters are now used for date ranges in v2.
