Account balance query API

Updated 2026-09-18 · Suno-API team

Endpoint description

The account balance query lets users check their New API account balance with their own API key. This endpoint only queries the balance; it triggers no generation task and charges nothing.

Endpoint: GET /api/user/balance

Billing: Free.

Balance unit: yuan. In the response, effective_amount has already been converted by quota_per_unit into the yuan amount a user can understand.

Request parameters

Headers

Query parameters

Field reference

Notes

• This endpoint uses the same API key as the generation endpoints.
• When an API key's balance is exhausted, balance queries are still allowed.
• Disabled or expired API keys cannot query.
• The endpoint does not return USD, CNY, $ or ¥; it always uses yuan, to avoid misunderstandings.
