- Created new src/routes/unified.js (225 lines)
- detectBackendFromModel(): Detects backend from model name
- routeToBackend(): Routes to Claude/OpenAI/Gemini with permission checks
- POST /v1/chat/completions: OpenAI-compatible endpoint with intelligent routing
- POST /v1/completions: Legacy completions endpoint with intelligent routing
- Updated src/routes/api.js (reduced from 1185 to 968 lines)
- Removed ~217 lines of routing logic
- Kept Claude-specific endpoints (/api/v1/messages)
- Maintained all other Claude API functionality
- Updated src/app.js
- Added unifiedRoutes registration at /api prefix
Benefits:
- Single responsibility: api.js focuses on Claude API routes
- Better organization: routing logic isolated in unified.js
- Easier maintenance: changes to routing won't affect Claude code
- File size reduction: api.js reduced by 18%
Tested:
- ✅ Claude model routing via /v1/chat/completions
- ✅ OpenAI model routing (correct backend detection)
- ✅ Gemini model routing (correct backend detection)
- ✅ Legacy /v1/completions endpoint
- ✅ All tests pass, no regressions

Add dedicated API endpoint to fetch Claude account OAuth usage data
asynchronously, improving user experience by eliminating the need for
multiple page refreshes to view session window statistics.
Backend changes:
- Add GET /admin/claude-accounts/usage endpoint for batch fetching
- Implement fetchOAuthUsage() to call Claude API /api/oauth/usage
- Add buildClaudeUsageSnapshot() to construct frontend data structure
- Add updateClaudeUsageSnapshot() to persist data to Redis
- Add _toNumberOrNull() helper for safe type conversion
- Update getAllAccounts() to return claudeUsage from Redis cache
Data structure:
- Store three window types: 5h, 7d, 7d-Opus
- Track utilization percentage and reset timestamps
- Calculate remaining seconds for each window
Performance optimizations:
- Concurrent batch requests using Promise.allSettled
- Graceful error handling per account
- Non-blocking async execution
