What's Wrong?

The Claude Code Analytics API (https://docs.claude.com/en/api/claude-code-analytics-api#get-analytics-for-a-specific-day) does not return usage for Claude.ai subscription users. Only users with customer_type=api that logged in using the Anthropic Console option show up in the API response.

What Should Happen?

The API response should return all Claude Code users, including users that log in with the Claude.ai subscription option in VS Code.

Additional Information

Logging in via the CLI also did not make a difference.

Developers who used a Claude.ai subscription still show up in the web dashboard, just not the analytics API response.

There are payloads returned to the UI that show 0 active users but non-zero lines of code accepted, which also presents an inconsistency.
