fix: _isGrokXAI() false-positive substring match breaks token usage for domains containing "x.ai" - #1484
Conversation
… domains containing 'x.ai' Fixes Zoo-Code-Org#1483 The _isGrokXAI() method used urlHost.includes('x.ai') which matches any domain containing 'x.ai' as a substring (e.g. box.ai, fox.ai, max.ai). This false-positive causes stream_options:{include_usage:true} to be omitted, so the API never returns usage data and the token bar shows 0. Fix: Use exact host match (api.x.ai) or subdomain match (*.x.ai) instead of substring includes. Added tests for false-positive scenarios and valid x.ai domain detection. AI-assisted: developed with Zoo Code/GLM-5.2, reviewed and verified by the contributor.

| Fix `_isGrokXAI()` false-positive substring match that broke token usage for OpenAI-compatible providers whose domain contains "x.ai" as a substring (e.g. box.ai, fox.ai, max.ai). | ||
|
|
||
| The `_isGrokXAI()` method in `src/api/providers/openai.ts` used `urlHost.includes("x.ai")` which is a substring match. Any domain containing "x.ai" anywhere in its host (e.g. `box.ai`, `fox.ai`, `max.ai`) was falsely identified as a Grok/xAI endpoint. This caused `stream_options: { include_usage: true }` to be omitted from API requests in both `createMessage()` and `handleO3FamilyMessage()`, so the API never returned usage data and the token bar showed 0 — a silent failure with no error message. | ||
|
|
||
| Fixed by using exact host match (`api.x.ai`) or subdomain suffix check (`.x.ai`) instead of substring `includes()`. |

Use the URL hostname for xAI matching.
For https://api.x.ai:8443/v1, URL.host returns api.x.ai:8443, so _isGrokXAI() returns false and the streaming request includes stream_options. Return URL.hostname and add an explicit-port regression test.

Summary
The
_isGrokXAI()method insrc/api/providers/openai.tsusedurlHost.includes("x.ai")which is a substring match. Any domain containing "x.ai" as a substring (e.g.box.ai,fox.ai,max.ai) was falsely identified as a Grok/xAI endpoint. This causedstream_options: { include_usage: true }to be omitted from API requests, so the API never returned usage data and the token bar showed 0 — a silent failure with no error message.Root Cause
The bug affects two code paths:
createMessage()— main message streaming (line 153)handleO3FamilyMessage()— O3 family model streaming (line 351)Both conditionally omit
stream_optionswhen_isGrokXAI()returns true:Fix
This ensures only
api.x.aiand subdomains ofx.ai(e.g.custom.x.ai) are detected as Grok/xAI endpoints.Changes
src/api/providers/openai.ts: Changed_isGrokXAI()to use exact host match or subdomain suffix check instead of substringincludes()src/api/providers/__tests__/openai.spec.ts: Added test suite "Grok xAI false-positive prevention" with 5 test cases:box.aishould NOT be detected as Grok xAIfox.aiandmax.aishould NOT be detected as Grok xAIapi.x.aiSHOULD be detected as Grok xAIcustom.x.ai(subdomain) SHOULD be detected as Grok xAIstream_optionsshould be included when using a non-Grok provider whose URL contains "x.ai" substringTesting
All existing Grok xAI tests continue to pass. New tests verify the false-positive scenarios are fixed.
