What
The internal data used for /usage-style rate-limit reporting has grown three new fields:
overagePeriodMonthly.utilization— how much of a monthly overage allowance has been usedoveragePeriodChannel.utilization— how much of a channel-scoped overage allowance has been usedrateLimitGraceActive— a flag marking whether a grace period is currently active
These sit alongside the overage fields that already existed in this data shape.
Why
This gives Claude Code more detail to draw on when reporting usage and rate limits, including tracking overage separately by month and by channel, and recognizing when an account is in a grace period rather than fully rate-limited.
Names in the bundle/usage
The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.
Added since
A small documentation edit on First request touched a line naming /usage after this was published.
For complete parameter details and response schemas, see the [Claude Code Analytics API reference](https://platform.claude.com/docs/en/api/beta/organization/usage_report/retrieve_claude_code).manage-claude/claude-code-analytics-api see the edit
Confirmed since
Anthropic's documentation has since written up /usage, on Claude Code changelog.
* Improved keyboard navigation in tabbed dialogs such as `/permissions` and `/usage`: ↑/↓ move focus between the tab row and the content, and a list responds to keys only while it has focuschangelog see the edit
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
The writer flagged doubt
The finding does not say whether or when this new data is actually surfaced to users in `/usage` output.
Anthropic's documentation agrees
