Phase 02-02: fal.ai Provider Summary

fal.ai provider with model discovery via REST API, filtered to image/video categories, with optional API key authentication

Performance

• Duration: 5 min
• Started: 2026-01-09T execution start
• Completed: 2026-01-09T execution end
• Tasks: 2
• Files created: 2

Accomplishments

• Created fal.ai provider implementing full ProviderInterface contract
• Built API route for server-side model fetching with optional API key
• Implemented category-based filtering to text-to-image, image-to-image, text-to-video, image-to-video
• Provider self-registers in registry when module is imported
• Works without API key (rate limited) unlike Replicate which requires auth

Task Commits

Each task was committed atomically:

1. Task 1: Create fal.ai provider implementation - 523bc1f (feat)
2. Task 2: Create fal.ai models API route - 3d4a97f (feat)

Files Created/Modified

• src/lib/providers/fal.ts - fal.ai provider with listModels, searchModels, getModel, isConfigured, getApiKey
• src/app/api/providers/fal/models/route.ts - GET endpoint for model fetching with optional X-API-Key auth

Decisions Made

• fal.ai category field maps directly to ModelCapability (no keyword inference needed unlike Replicate)
• API key authentication is optional - fal.ai works without but with lower rate limits
• Authorization header uses "Key" prefix (fal.ai format) rather than "Bearer" (Replicate format)
• Status filter set to "active" to exclude deprecated models
• generate() returns stub error - implementation deferred to Phase 3

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None.

Next Phase Readiness

• fal.ai provider complete and ready for use
• Both providers (Replicate and fal.ai) now implemented
• Model caching to be added in 02-03
• Two different auth patterns documented (required vs optional)
