English reading guide. The complete Chinese specification remains the authoritative source for exact fields, examples, implementation status, and historical details. This page is a concise guide, not a full translation.

Separate account state from service availability

• Subscription state, credit balance, capabilities, and actual cloud calls must be checked against the current account and supported API contract.
