Auth: API Key only — not available with OAuth tokens. The caller’s identity is derived entirely from the API key, so the request takes no parameters.

Scope: For an API key that belongs to a team sub-account, the response reflects the team’s shared credit pool. For a personal account, it reflects the personal balance.

total_credits is authoritative: Treat total_credits as the single source of truth for spendable balance. Other fields break down where the credits come from but do not always sum to total_credits — when the membership has lapsed, periodic_credits and addon_credits are excluded from the total even though addon_credits still reports its real (non-zero) balance.

Quota vs. balance: pro_monthly_credits and max_refresh_credits describe how much will be issued; periodic_credits and refresh_credits are how much currently remains.

Personal accounts only: max_refresh_credits, next_refresh_time, and refresh_interval are populated only for personal accounts. Team accounts have no daily/weekly refresh, so these return 0 / 0 / "". Time fields are Unix timestamps in seconds (UTC), not milliseconds.

Headers

x-manus-api-key

string

required

API key for authentication. This endpoint does not support OAuth2 tokens. See Authentication.

Response

Available credits retrieved successfully.

boolean

Whether the request was successful.

Example:

true

request_id

string

Unique identifier for this API request.

data

object

Credit balance and refresh information for the API key's caller. All credit fields are 32-bit integers in credit points. total_credits is the authoritative spendable balance — see the field descriptions for how it is composed.

Hide child attributes

data.total_credits

integer

Total available credits — the actual spendable wallet balance. Equals free_credits + periodic_credits + addon_credits + event_credits + refresh_credits, minus team overflow credits, where periodic_credits and addon_credits are counted as 0 when the membership has lapsed and event_credits is 0 when no event is active. Always treat this as the single authoritative value for how many credits can be spent.

data.free_credits

integer

Free credits unrelated to any subscription, such as sign-up gifts and system grants.

data.periodic_credits

integer

Remaining periodic subscription credits issued in the current billing cycle and not yet spent. Returns 0 when the membership has lapsed.

data.addon_credits

integer

Remaining add-on / credit-pack credits that were purchased separately and do not reset with the subscription cycle. In team scenarios this already accounts for deducted-but-unpaid overflow credits.

data.pro_monthly_credits

integer

VIP monthly periodic-credit quota — how many periodic credits the current membership tier issues each month. This is a quota, not a current balance. 0 for non-VIP accounts.

data.event_credits

integer

Remaining event (live event) credits. Returns the real value only while the account's bound campaign is still active; otherwise 0.

data.refresh_credits

integer

Remaining auto-refresh credits accumulated on the account (daily/weekly) and not yet spent.

data.max_refresh_credits

integer

Amount granted by a single refresh — the cap the next auto-refresh will issue. Only present for personal accounts; 0 for team accounts.

data.next_refresh_time

integer

Time of the next refresh as a Unix timestamp in seconds (UTC). Only present for personal accounts; 0 when there is no upcoming refresh.

data.refresh_interval

enum<string>

Refresh cadence: daily or weekly. Empty string when there is no refresh schedule (e.g., team accounts).

Available options:

daily,

weekly,
