Authentication

All endpoints require authentication unless AUTH_ENABLED=false.

Session Token

# Login
curl -X POST http://localhost:1349/api/auth/login \
  -H "Content-Type: application/json" \
  -d '{"username":"admin","password":"admin"}'
# Returns: {"token":"<session-token>"}

# Use token
curl http://localhost:1349/api/v1/tools/image/resize \
  -H "Authorization: Bearer <session-token>"

Sessions expire after 7 days (configurable via SESSION_DURATION_HOURS).

API Keys

# Create a key (returns key once - store it)
curl -X POST http://localhost:1349/api/v1/api-keys \
  -H "Authorization: Bearer <session-token>" \
  -H "Content-Type: application/json" \
  -d '{"name":"my-script"}'
# Returns: {"key":"si_<96 hex chars>","id":"...","name":"my-script"}

# Use the key
curl http://localhost:1349/api/v1/tools/image/resize \
  -H "Authorization: Bearer si_<your-key>"

Keys are prefixed si_ and stored as scrypt hashes - the raw key is shown once and never retrievable again.

Auth Endpoints

Method	Path	Access	Description

GET	/api/auth/session	Auth	Validate current session
POST	/api/auth/change-password	Auth	Change own password (invalidates all other sessions + API keys)
GET	/api/auth/users	Admin	List all users
POST	/api/auth/register	Admin	Create a new user
PUT	/api/auth/users/:id	Admin	Update user role or team
POST	/api/auth/users/:id/reset-password	Admin	Reset user's password
DELETE	/api/auth/users/:id	Admin	Delete a user

Health Check

Method	Path	Access	Description
GET	/api/v1/health	Public	Basic health check. Returns {"status":"healthy","version":"..."} with 200, or {"status":"unhealthy"} with 503 if the database is unreachable.
GET	/api/v1/admin/health	Admin (system:health)	Detailed diagnostics including uptime, storage mode, database status, queue state, and GPU availability.

Using Tools

Every tool follows the same pattern:

# Single file
curl -X POST http://localhost:1349/api/v1/tools/<section>/<toolId> \
  -H "Authorization: Bearer <token>" \
  -F "file=@input.jpg" \
  -F 'settings={"width":800,"height":600}'

# Batch (returns ZIP)
curl -X POST http://localhost:1349/api/v1/tools/<section>/<toolId>/batch \
  -H "Authorization: Bearer <token>" \
  -F "files=@a.jpg" \
  -F "files=@b.jpg" \
  -F 'settings={...}'

<section> is one of image, video, audio, pdf, or files.

• Upload is multipart/form-data.
• settings is a JSON string with tool-specific options.
• Fast tools (200) return JSON: {"jobId":"...","downloadUrl":"/api/v1/download/<jobId>/<filename>","originalSize":1234,"processedSize":567}. Fetch the processed file from downloadUrl.
• Long-running tools (202) return JSON: {"jobId":"...","async":true}. Connect to SSE for progress, then download when complete (see Progress Tracking).
• Batch returns a ZIP archive streamed directly (with X-Job-Id header).
