Open Usage in your workspace to inspect the account’s allocation and recent request outcomes. This control read is free.
Understand the counters
Limit: the current included-credit allocation.
Used: credits settled for completed eligible responses.
Reserved: capacity temporarily held for requests still settling.
Remaining: capacity after used and reserved credits.
Reset: the exact UTC boundary of the current cycle.
Concurrent requests can make headers differ from a later Usage read. A reservation is not proof that the client consumed data. Unknown expired holds are recovered without retrospective charging.
When requests are blocked
A 402 may mean no quota policy or exhausted credits. A 429 is a separate rate/abuse window; follow its Retry-After value. Free account checks and errors remain free at zero data quota. Overage is disabled.
If a result looks wrong, send support the request ID, approximate UTC time and operation. Do not send the key, Authorization header or a full private response. An API-key rotation does not refill the account.
