Summary

• Read the xAI subscription tier before applying weekly credits.
• Skip the weekly allowance for free accounts.
• Treat a missing creditUsagePercent on a weekly period as 0% usage for paid plans.
• Derive the plan name from subscriptionTier when monthly billing does not identify one.

Problem

/v1/billing?format=credits returns a weekly period for free accounts as well as paid subscriptions. Free accounts are not entitled to that allowance, but the collector previously turned the response into an xai-weekly-usage window.

Paid accounts at 0% usage are also easy to miss. proto3 JSON omits creditUsagePercent when the value is zero, so dropping that response hides a valid weekly window.

Solution

Request /v1/user?include=subscription and branch on subscriptionTier:

• null, an empty string, free, or none: skip weekly credits.
• A paid tier: keep the weekly window. A missing percent is recorded as 0/100.
• Profile request failure, or a response with no tier field: keep the previous behavior and still apply weekly credits.
• When monthly billing does not identify a plan, use the tier name: SuperGrok, SuperGrok Plus, or SuperGrok Heavy.

The stored profile base URL stays https://cli-chat-proxy.grok.com/v1/user. include=subscription is added only when the request is sent.

Tests

• go test ./internal/quota/...
• CGO_ENABLED=1 go build -o test-output ./cmd/home
