API Reference

ryOS backend APIs use Node.js route handlers in api/, deployable on Vercel or the standalone Bun API server.

Most actively refactored JSON routes use the shared apiHandler utility (api/_utils/api-handler.ts) for CORS, method checks, auth resolution, and consistent error handling. Some specialized routes (for example multipart upload handlers) still use explicit/manual handling.

Endpoint Documentation

Cross-Cutting Handler Pattern

• apiHandler: shared wrapper for CORS preflight, origin checks, method allowlists, optional JSON parsing, unified logger wiring, and default JSON error handling.

• request-auth: shared auth resolver for token endpoints, expecting:
  • Authorization: Bearer {token}
  • X-Username: {username}
• Partial auth headers return 400.
• Invalid token/username pairs return 401.
• Optional-auth endpoints can be anonymous while still validating provided auth headers.

Infrastructure Adapters

• Redis (api/_utils/redis.ts): Centralized Redis client factory supporting Upstash REST (REDIS_KV_REST_API_URL) and standard Redis (REDIS_URL) backends with a unified API.

• Storage (api/_utils/storage.ts): Switchable object storage adapter supporting Vercel Blob and S3-compatible backends for cloud backups and sync.

Authentication

Authorization: Bearer {token}
X-Username: {username}

Token-based sessions use a 90-day TTL. Auth-required endpoints use the shared request-auth validation boundary for consistent 400/401 semantics.
