Get prepaid balance (deprecated alias)

GET /v1/api-gateway/moon-reserve

Superseded by GET /v1/api-gateway/moon-credit, which is the same endpoint under the current name and returns the identical response. This path keeps working and nothing about its behaviour has changed; point new integrations at moon-credit. Available prepaid balance for the organization. Returns balance: 0 when no prepaid balance account exists yet.
