Phase 02 Fix: fal.ai API 400 Error Summary

Removed multiple category params from fal.ai API requests to fix 400 error - models now filtered client-side

Performance

• Duration: 5 min
• Started: 2026-01-09
• Completed: 2026-01-09
• Tasks: 1
• Files modified: 2

Accomplishments

• Fixed UAT-001: fal.ai models endpoint now returns 200 with models array
• Removed buildCategoryFilter() function from both route.ts and fal.ts
• Models still correctly filtered to relevant categories (text-to-image, image-to-image, text-to-video, image-to-video)

Task Commits

1. Task 1: Fix UAT-001 - Multiple category parameters causing 400 error - 2fe312d (fix)

Files Created/Modified

• src/app/api/providers/fal/models/route.ts - Removed buildCategoryFilter(), simplified URL to use only status=active
• src/lib/providers/fal.ts - Same fix applied to listModels() and searchModels() methods

Decisions Made

• Fetch all active models without category filter, rely on existing isRelevantModel() function to filter results
• This approach is simpler than making 4 parallel API calls (one per category)
• fal.ai returns a manageable number of models, so client-side filtering is efficient

Deviations from Plan

None - plan executed exactly as written

Issues Encountered

None

Next Phase Readiness

• fal.ai provider is now fully functional
• Ready to proceed with additional provider implementations or UI integration
