Problem Statement

Hello Anthropic Team,

I am a heavy user of Claude Code and currently manage multiple accounts (e.g., Personal and Work). I have built a custom monitoring dashboard to track my 5-hour and weekly usage limits across these accounts to better manage my workflow.

However, I frequently encounter 403 Forbidden errors and session revocations when querying api.anthropic.com/api/oauth/usage from a secondary tool, even when using the official client_id.

Request:

Proposed Solution

Could you provide a stable, documented way to query usage limits for multiple authenticated accounts?

Ideally, a "Read-Only Usage API Key" would be perfect for dashboards like mine, so I don't have to rely on OAuth session tokens that expire or get revoked during inactivity.

Supporting a first-party "Usage Dashboard" that can aggregate multiple accounts would also be a huge productivity boost.
