Get services by carrier and country

Returns the shipping service levels (e.g., ground, express, next-day) offered by a specific carrier in a given country. If no carrier is specified, returns all services for all carriers in that country.

When to use: Call this endpoint after selecting a carrier to populate the service-level dropdown in your shipping form, or to discover all available service tiers before requesting a quote.

Prerequisites:

• Valid JWT token in the Authorization header
• A valid two-letter ISO country code (e.g., MX, US, CO)
• Optionally, a carrier name obtained from the GET /carrier endpoint

Key behaviors:

• When carrier is omitted, returns services for all carriers in the specified country
• Each service object includes name (the service identifier used in quote/shipment requests), description, carrier, and active status
• The service name returned here is the exact value required by the Shipping API carrier_service field when creating a quote or shipment
• Only active services are returned by default
