What's Wrong?

Claude Code shows "Credit balance too low · Add funds: https://platform.claude.com/settings/billing" despite being logged in via subscription (managed key, Pro plan) with Extra Usage enabled and $49.47 remaining balance.

The error links to platform.claude.com — the API billing system — even though I am authenticated via claude.ai subscription login, not an API key. Claude Code appears to be checking the wrong billing system.

Version
Claude Code 2.1.92

Auth method: /login managed key (subscription, not API key)
Organization: Individual Org
Model: claude-sonnet-4-6

What Should Happen?

Expected Behavior

Claude Code should check the claude.ai subscription and Extra Usage balance, not the platform.claude.com API credit balance, when the user is authenticated via subscription login.

Actual Behavior

Error references platform.claude.com/settings/billing — the wrong billing system for subscription users. This caused me to purchase API credits on platform.claude.com unnecessarily before realizing the error was misleading.
