[Bug] Anthropic API Error: Extra usage required for 1M context access

Bug Description
Claude code complains that "Extra usage is required for 1M context"... FWIW i've been using the 1M context for a few days and it didn't complain until now. My extra usage is indeed turned off and it was working, so it feels like a glitch to me? I tried restarting and clearing and login. Limits are all under 25%, except Claude Design at 88%. On Max 20x.

Is the message just misleading and it means the servers are under stress? (it's written rate-limited and not "denied"). Maybe the error message should be clearer / more transparent?
