The credit balance is the prepaid funds remaining for requests, tracked to five decimal places because per-request costs are often fractions of a cent. Requests are rejected when the combined organization and personal balances cannot cover them, so balance health drives availability.
Why it matters
Because per-request costs are often fractions of a cent, the balance must be precise. It also drives availability: when it cannot cover a request, the request is rejected.
How it works
The balance is tracked to five decimal places and shown with status levels (Normal, Warning, Critical, No Credit). Organization balances are consumed before personal balances for org tokens.
