CLIProxyAPI lists Grok subscription credentials with provider xai, but T3's hub reader filters them out and only reads Codex and Claude accounts. Connecting a hub therefore never produces Grok limits, even when the hub can read the account's billing data.
Include enabled xai accounts, map them to the Grok driver, and read the CLI billing endpoint through the existing management api-call route with token substitution and Grok identity headers. Reuse the native Grok billing schema and window conversion so quota percentages and reset dates behave consistently. Failed reads remain isolated to the account; missing percentages do not become fabricated zero-usage quotas. Native probe warnings remain unchanged because a hub account need not be the local account.
This is a focused fix to the existing hub limits workflow: no new settings, contracts, inference requests, or client-specific UI. The provider naming and billing route were checked against CLIProxyAPI's management UI and its request constants.
Validation:
vp test run apps/server/src/usage/cliproxyApi.test.ts apps/server/src/provider/GrokProvider.test.ts — 57 tests passed, including weekly/monthly Grok windows, proxy headers and account selection, absent percentages, upstream rejection, malformed billing data, disabled accounts, and rejection of Codex reset-credit redemption for Grok.vp lint on the three changed TypeScript files — passed.tsc-rs --noEmit in apps/server and packages/provider-grok — passed (existing advisory Effect suggestions).git diff --check — passed.Live authenticated Grok billing and a rendered client were not verified. API-only accounts without access to the CLI billing endpoint still cannot report subscription quotas. The local dependency install's prepare hook failed to resolve the macOS Effect tsgo replacement; the installed vp and tsc-rs binaries successfully ran the checks above.
Implemented with GPT-6 Astra through the Codex harness in T3 Code.

Verdict: Needs Human Approval
Macroscope's review found this PR requires human approval — The production hub reader now automatically processes enabled Grok accounts and retrieves subscription quota data through Grok’s billing endpoint. This changes metering-related runtime behavior and adds a new externally observable account path, despite the localized implementation and accompanying tests.

CLIProxyAPI now includes enabled xAI accounts and reads Grok billing usage as subscription limits. The change exports the Grok usage response schema, groups Grok limits by period, and updates related tests and usage documentation.

|---|---|
Grok usage response contract packages/provider-grok/package.json, packages/provider-grok/src/server/usageLimits.ts, apps/server/src/usage/cliproxyApi.ts | The provider package exports GrokUsageResponse. CLIProxyAPI decodes Grok usage responses with the schema. |
xAI account usage integration apps/server/src/usage/cliproxyApi.ts, packages/shared/src/usageLimits.ts, apps/server/src/usage/cliproxyApi.test.ts, docs/user/usage.md | CLIProxyAPI adds xAI-specific headers, maps xAI accounts to the Grok driver, reads billing data from two endpoints, and lists enabled xAI accounts. Shared limit pooling groups Grok windows by period. Tests cover billing responses, account handling, and credit redemption. The documentation describes Grok account limits. |

2edeeGrok billing reads both endpoints and forwards identity when available. No merge-blocking issue remains; live account validation is still outstanding.
b563cThis is a bounded, read-only integration through the existing authenticated hub. Account selection, error isolation, and restrictions on credit redemption remain intact. End-to-end credential handling by the external hub was not verified.

Explanation
The title "fix(server): read Grok usage limits through CLIProxyAPI" matches the main change. The changeset adds enabled xai accounts to the hub limits reader, maps them to the Grok driver, and reads Grok billing through the CLIProxyAPI management api-call route. The title is short, uses a conventional commit prefix, and names the scope and the main behavior. It does not cover every detail, such as the poolKey change or the docs update, which is acceptable.
Explanation
The description follows the template's main sections and covers the problem, the change, and verification. The Problem section is implied by the opening paragraph: xai accounts are filtered out, so no Grok limits appear. The Change section is detailed. The Scope and approval section is missing. It does not link a triaged bug issue or a discussion with maintainer approval, and it does not explain why the fix qualifies without one. The Verification section is strong: it lists specific tests, lint, typecheck, and unverified areas. The description also omits the model and harness line in the form the template asks for, though it does include 'Implemented with GPT-6 Astra through the Codex harness in T3 Code.' The author should add the scope and approval justification, and should label the problem more explicitly.
Resolution
Add a "Scope and approval" justification. Link the triaged bug issue or the discussion that contains explicit maintainer approval, with the approval comment. If no prior issue exists, explain why this very small, focused fix of an obvious bug qualifies without one. Label the opening paragraph as a "Problem" section with the expected behavior and reproduction steps or environment. Keep the verification section as written.

merged current main with a merge commit, preserving both the grok regression tests and main's claude spend/extra-usage tests. the existing fixes retain oauth identity forwarding, independent billing endpoints with failure isolation, and native/hub pooling by period. no further product changes were needed.
verified through blacksmith: vp run check:changed passed formatting, lint, knip, graphql generation, 39 package typechecks, and 85 tests. two independent scoped reviews approved 2edeee6a311d51300d1bcf9f83d4d9000d355fa3.
live grok billing and client integration remain unverified because no account credentials are available. the existing freshest-snapshot policy remains unchanged; older periods are not combined into a newer authoritative account snapshot.

31-34: External image Major · Data Integrity & Integration · Heavy liftExternal image Unverified finding Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Verify that the hub supplies the Grok subject. The inspected CLIProxyAPI
/auth-filesimplementation builds each response entry explicitly. It does not emitsub,subject,user_id, oruserId. As a result, this schema cannot provide a value forx-useridat Line 231, although the test fixture supplies one. For an account whose billing request requires that header, both reads can fail and the account becomesprobeFailed. Check a redacted response from the supported hub version. If it also omits the subject, retrieve the identity through an account-specific source before building the billing headers. (raw.githubusercontent.com)
