# Prompt di Ingaggio: Background Tasks (T55-T58)
## 🎯 MISSIONE
Implementare i **Background Tasks** per sincronizzare automaticamente i dati da OpenRouter, validare API keys periodicamente e gestire la pulizia dei dati storici.
**Task da completare:** T55, T56, T57, T58
---
## 📋 CONTESTO
**AGENTE:** @tdd-developer
**Repository:** `/home/google/Sources/LucaSacchiNet/openrouter-watcher`
**Stato Attuale:**
- ✅ MVP Backend completato: 43/74 task (58%)
- ✅ 418+ test passanti, ~98% coverage
- ✅ Tutte le API REST implementate
- ✅ Docker support pronto
- 🎯 **Manca:** Sincronizzazione automatica dati da OpenRouter
**Perché questa fase è critica:**
Attualmente l'applicazione espone API per visualizzare statistiche, ma i dati in `UsageStats` sono vuoti (popolati solo manualmente). I background tasks sono necessari per:
1. Chiamare periodicamente le API di OpenRouter
2. Recuperare usage stats (richieste, token, costi)
3. Salvare i dati nel database
4. Mantenere le statistiche aggiornate automaticamente
**Servizi Pronti:**
- `validate_api_key()` in `services/openrouter.py` - già implementato
- `UsageStats` model - pronto
- `EncryptionService` - per decifrare API keys
- `get_db()` - per sessioni database
**Documentazione OpenRouter:**
- Endpoint usage: `GET https://openrouter.ai/api/v1/usage`
- Authentication: `Authorization: Bearer {api_key}`
- Query params: `start_date`, `end_date`
- Rate limit: 20 richieste/minuto
---
## 🔧 TASK DA IMPLEMENTARE
### T55: Setup APScheduler per Task Periodici
**File:** `src/openrouter_monitor/tasks/scheduler.py`, `src/openrouter_monitor/tasks/__init__.py`
**Requisiti:**
- Installare `APScheduler` (`pip install apscheduler`)
- Creare scheduler singleton con `AsyncIOScheduler`
- Configurare job stores (memory per MVP, opzionale Redis in futuro)
- Gestire startup/shutdown dell'applicazione FastAPI
- Supportare timezone UTC
**Implementazione:**
```python
# src/openrouter_monitor/tasks/scheduler.py
from apscheduler.schedulers.asyncio import AsyncIOScheduler
from apscheduler.triggers.interval import IntervalTrigger
from apscheduler.triggers.cron import CronTrigger
from apscheduler.events import EVENT_JOB_ERROR, EVENT_JOB_EXECUTED
import logging
logger = logging.getLogger(__name__)
# Singleton scheduler
_scheduler: AsyncIOScheduler | None = None
def get_scheduler() -> AsyncIOScheduler:
"""Get or create scheduler singleton."""
global _scheduler
if _scheduler is None:
_scheduler = AsyncIOScheduler(timezone='UTC')
return _scheduler
def init_scheduler():
"""Initialize and start scheduler."""
scheduler = get_scheduler()
# Add event listeners
scheduler.add_listener(
_job_error_listener,
EVENT_JOB_ERROR
)
if not scheduler.running:
scheduler.start()
logger.info("Scheduler started")
def shutdown_scheduler():
"""Shutdown scheduler gracefully."""
global _scheduler
if _scheduler and _scheduler.running:
_scheduler.shutdown()
logger.info("Scheduler shutdown")
def _job_error_listener(event):
"""Handle job execution errors."""
logger.error(f"Job {event.job_id} crashed: {event.exception}")
# Convenience decorator for tasks
def scheduled_job(trigger, **trigger_args):
"""Decorator to register scheduled jobs."""
def decorator(func):
scheduler = get_scheduler()
scheduler.add_job(
func,
trigger=trigger,
**trigger_args,
id=func.__name__,
replace_existing=True
)
return func
return decorator
```
**Integrazione con FastAPI:**
```python
# In main.py
from contextlib import asynccontextmanager
from openrouter_monitor.tasks.scheduler import init_scheduler, shutdown_scheduler
@asynccontextmanager
async def lifespan(app: FastAPI):
# Startup
init_scheduler()
yield
# Shutdown
shutdown_scheduler()
app = FastAPI(lifespan=lifespan)
```
**Test:** `tests/unit/tasks/test_scheduler.py`
- Test singleton scheduler
- Test init/shutdown
- Test job registration
- Test event listeners
---
### T56: Task Sincronizzazione OpenRouter
**File:** `src/openrouter_monitor/tasks/sync.py`
**Requisiti:**
- Task che gira ogni ora (`IntervalTrigger(hours=1)`)
- Per ogni API key attiva:
1. Decifra la key con `EncryptionService`
2. Chiama OpenRouter API `/usage`
3. Recupera dati: date, model, requests, tokens, cost
4. Salva in `UsageStats` (upsert per evitare duplicati)
- Gestire rate limiting (max 20 req/min)
- Gestire errori (API down, key invalida)
- Logging dettagliato
**Implementazione:**
```python

### T57: Task Validazione API Keys
**File:** `src/openrouter_monitor/tasks/sync.py` (aggiungere funzione)
**Requisiti:**
- Task che gira ogni giorno (`CronTrigger(hour=2, minute=0)`)
- Per ogni API key:
1. Decifra la key
2. Chiama OpenRouter `/auth/key` per validare
3. Se invalida: set `is_active=False`
4. Logga key invalidate
- Notifica opzionale (per MVP solo logging)
**Implementazione:**
```python
async def validate_api_keys():
"""Validate all API keys and mark invalid ones."""
logger.info("Starting API keys validation")
db = SessionLocal()
try:
api_keys = db.query(ApiKey).filter(ApiKey.is_active == True).all()

headers={"Authorization": f"Bearer {plaintext_key}"}
)
if response.status_code != 200:
# Key is invalid
api_key.is_active = False
invalid_count += 1
logger.warning(f"API key {api_key.id} marked as invalid")

### T58: Task Cleanup Dati Vecchi
**File:** `src/openrouter_monitor/tasks/cleanup.py`
**Requisiti:**
- Task che gira ogni settimana (`CronTrigger(day_of_week='sun', hour=3, minute=0)`)
- Rimuove `UsageStats` più vecchi di X giorni (configurabile, default 365)
- Mantiene dati aggregati (opzionale per MVP)
- Logga numero record eliminati
**Implementazione:**
```python

```
**Test:** `tests/unit/tasks/test_cleanup.py`
- Test eliminazione dati vecchi
- Test conservazione dati recenti
- Test configurazione retention_days
---
## 🔄 WORKFLOW TDD
Per **OGNI** task:
1. **RED**: Scrivi test che fallisce (prima del codice!)
2. **GREEN**: Implementa codice minimo per passare il test
3. **REFACTOR**: Migliora codice, test rimangono verdi

| sync_usage_stats | Ogni ora | - | Recupera dati da OpenRouter |
| validate_api_keys | Giornaliera | 02:00 | Verifica validità API keys |
| cleanup_old_usage_stats | Settimanale | Dom 03:00 | Pulizia dati vecchi |
---
## ⚠️ NOTE IMPORTANTI
- **Rate Limiting**: OpenRouter ha limiti. Usa `asyncio.sleep()` tra richieste
- **Error Handling**: Task non devono crashare l'applicazione
- **Logging**: Tutte le operazioni devono essere loggate
- **Database**: Ogni task crea la propria sessione (non condividere tra thread)
- **Timezone**: Usa sempre UTC
- **Idempotenza**: Il task sync deve gestire upsert (non creare duplicati)
---
## 🔍 TESTING MANUALE
Dopo l'implementazione:
1. **Aggiungi una API key** via POST /api/keys
2. **Verifica nel log** che il task sync parta (o attendi 1 ora)
3. **Forza esecuzione** per test:
```python
from openrouter_monitor.tasks.sync import sync_usage_stats
import asyncio
asyncio.run(sync_usage_stats())
```
4. **Verifica dati** in GET /api/usage (dovrebbero esserci dati)
---
**AGENTE:** @tdd-developer
**INIZIA CON:** T55 - Setup APScheduler
**QUANDO FINITO:** I dati si sincronizzeranno automaticamente da OpenRouter! 🚀

# Prompt di Ingaggio: Gestione Token API (T41-T43)
## 🎯 MISSIONE
Implementare la fase **Gestione Token API** per permettere agli utenti di generare, visualizzare e revocare i loro token API pubblici.
**Task da completare:** T41, T42, T43
---
## 📋 CONTESTO
**AGENTE:** @tdd-developer
**Repository:** `/home/google/Sources/LucaSacchiNet/openrouter-watcher`
**Stato Attuale:**
- ✅ Setup (T01-T05): 59 test
- ✅ Database & Models (T06-T11): 73 test
- ✅ Security Services (T12-T16): 70 test
- ✅ User Authentication (T17-T22): 34 test
- ✅ Gestione API Keys (T23-T29): 61 test
- ✅ Dashboard & Statistiche (T30-T34): 27 test
- ✅ API Pubblica (T35-T40): 70 test
- 🎯 **Totale: 394+ test, ~98% coverage sui moduli implementati**
**Servizi Pronti:**
- `generate_api_token()`, `verify_api_token()` - Generazione e verifica token
- `get_current_user()` - Autenticazione JWT
- `ApiToken` model - Database
- `ApiTokenCreate`, `ApiTokenResponse` schemas - Già creati in T35
**Flusso Token API:**
1. Utente autenticato (JWT) richiede nuovo token
2. Sistema genera token (`generate_api_token()`)
3. Token in plaintext mostrato UNA SOLA VOLTA all'utente
4. Hash SHA-256 salvato nel database
5. Utente usa token per chiamare API pubblica (/api/v1/*)
6. Utente può revocare token in qualsiasi momento
**Documentazione:**
- PRD: `/home/google/Sources/LucaSacchiNet/openrouter-watcher/prd.md` (sezione 2.4.1)
- Architecture: `/home/google/Sources/LucaSacchiNet/openrouter-watcher/export/architecture.md`

## 🔧 TASK DA IMPLEMENTARE
### T41: Implementare POST /api/tokens (Generazione Token)
**File:** `src/openrouter_monitor/routers/tokens.py`
**Requisiti:**
- Endpoint: `POST /api/tokens`
- Auth: JWT richiesto (`get_current_user`)
- Body: `ApiTokenCreate` (name: str, 1-100 chars)
- Limite: MAX_API_TOKENS_PER_USER (default 5, configurabile)
- Logica:
1. Verifica limite token per utente
2. Genera token: `generate_api_token()` → (plaintext, hash)
3. Salva nel DB: `ApiToken(user_id, token_hash, name)`
4. Ritorna: `ApiTokenCreateResponse` con token PLAINTEXT (solo questa volta!)
- Errori: limite raggiunto (400), nome invalido (422)
**Implementazione:**
```python
from fastapi import APIRouter, Depends, HTTPException, status

)
async def create_api_token(
token_data: ApiTokenCreate,
current_user: User = Depends(get_current_user),
db: Session = Depends(get_db)
):
"""Create a new API token for programmatic access.
The token is shown ONLY ONCE in the response. Store it securely!
Max 5 tokens per user (configurable).
"""
# Check token limit
current_count = db.query(func.count(ApiToken.id)).filter(
ApiToken.user_id == current_user.id,
ApiToken.is_active == True
).scalar()
if current_count >= settings.max_api_tokens_per_user:

return ApiTokenCreateResponse(
id=api_token.id,
name=api_token.name,

)
```
**Test:** `tests/unit/routers/test_tokens.py`
- Test creazione successo (201) con token in risposta
- Test limite massimo raggiunto (400)
- Test nome troppo lungo (422)
- Test senza autenticazione (401)
- Test token salvato come hash nel DB (non plaintext)
---
### T42: Implementare GET /api/tokens (Lista Token)
**File:** `src/openrouter_monitor/routers/tokens.py`
**Requisiti:**
- Endpoint: `GET /api/tokens`
- Auth: JWT richiesto
- Ritorna: lista di `ApiTokenResponse` (senza token plaintext!)
- Include: id, name, created_at, last_used_at, is_active
- Ordinamento: created_at DESC (più recenti prima)
- NO token values nelle risposte (mai!)
**Implementazione:**
```python
from typing import List
@router.get("", response_model=List[ApiTokenResponse])
async def list_api_tokens(
current_user: User = Depends(get_current_user),
db: Session = Depends(get_db)
):
"""List all API tokens for the current user.
Token values are NEVER exposed. Only metadata is shown.
"""
tokens = db.query(ApiToken).filter(
ApiToken.user_id == current_user.id
).order_by(ApiToken.created_at.desc()).all()
return [
ApiTokenResponse(
id=t.id,
name=t.name,
created_at=t.created_at,
last_used_at=t.last_used_at,
is_active=t.is_active
)
for t in tokens
]
```
**Test:**
- Test lista vuota (utente senza token)
- Test lista con token multipli
- Test ordinamento (più recenti prima)
- Test NO token values in risposta
- Test senza autenticazione (401)
---
### T43: Implementare DELETE /api/tokens/{id} (Revoca Token)
**File:** `src/openrouter_monitor/routers/tokens.py`
**Requisiti:**
- Endpoint: `DELETE /api/tokens/{token_id}`
- Auth: JWT richiesto
- Verifica: token esiste e appartiene all'utente corrente
- Soft delete: set `is_active = False` (non eliminare dal DB)
- Ritorna: 204 No Content
- Token revocato non può più essere usato per API pubblica
- Errori: token non trovato (404), non autorizzato (403)
**Implementazione:**
```python
@router.delete("/{token_id}", status_code=status.HTTP_204_NO_CONTENT)
async def revoke_api_token(
token_id: int,
current_user: User = Depends(get_current_user),
db: Session = Depends(get_db)
):
"""Revoke an API token.
The token is soft-deleted (is_active=False) and cannot be used anymore.
This action cannot be undone.
"""
api_token = db.query(ApiToken).filter(ApiToken.id == token_id).first()
if not api_token:
raise HTTPException(
status_code=status.HTTP_404_NOT_FOUND,
detail="API token not found"
)
if api_token.user_id != current_user.id:
raise HTTPException(
status_code=status.HTTP_403_FORBIDDEN,
detail="Not authorized to revoke this token"
)
# Soft delete: mark as inactive
api_token.is_active = False
db.commit()
return None
```
**Test:**
- Test revoca successo (204)
- Test token non trovato (404)
- Test token di altro utente (403)
- Test token già revocato (idempotent)
- Test token revocato non funziona più su API pubblica
- Test senza autenticazione (401)

## 📊 FLUSSO COMPLETO TOKEN API
```
1. Utente autenticato (JWT)
↓
2. POST /api/tokens {"name": "My Token"}
↓
3. Server genera: (or_api_abc123..., hash_abc123...)
↓
4. Salva hash nel DB
↓
5. Ritorna: {"id": 1, "name": "My Token", "token": "or_api_abc123..."}
⚠️ Token mostrato SOLO questa volta!
↓
6. Utente salva token in modo sicuro
↓
7. Usa token per chiamare API pubblica:
GET /api/v1/stats
Authorization: Bearer or_api_abc123...
↓
8. Server verifica hash, aggiorna last_used_at
↓
9. Utente può revocare token:
DELETE /api/tokens/1
↓
10. Token revocato non funziona più
```
---
## 🔒 SICUREZZA CRITICA
### ⚠️ IMPORTANTE: Token in Plaintext
**DO:**
- ✅ Mostrare token in plaintext SOLO nella risposta POST /api/tokens
- ✅ Salvare SOLO hash SHA-256 nel database
- ✅ Documentare chiaramente che il token viene mostrato una sola volta
- ✅ Consigliare all'utente di salvarlo immediatamente
**DON'T:**
- ❌ MAI ritornare token plaintext in GET /api/tokens
- ❌ MAI loggare token in plaintext
- ❌ MAI salvare token plaintext nel database
- ❌ MAI permettere di recuperare token dopo la creazione
### Soft Delete vs Hard Delete
**Soft delete** (is_active=False) è preferito:
- Mantiene storico utilizzo
- Preverte errori utente (recupero impossibile con hard delete)
- Permette audit trail
- Il token non può più essere usato, ma rimane nel DB
---
## 📝 NOTE IMPORTANTI
- **Path assoluti**: Usa sempre `/home/google/Sources/LucaSacchiNet/openrouter-watcher/`
- **MAX_API_TOKENS_PER_USER**: Aggiungi a config.py (default 5)
- **Autenticazione**: Usa JWT (get_current_user), non API token
- **Verifica ownership**: Ogni operazione deve verificare user_id
- **Soft delete**: DELETE setta is_active=False, non rimuove dal DB
- **Rate limiting**: Non applicare a /api/tokens (gestito da JWT)

@router.get("/stats", response_model=PublicStatsResponse, dependencies=[Depends(rate_limit_by_token)])
async def get_public_stats_endpoint(...):
...
```
**Test:**
- Test rate limit token (100/ora)
- Test rate limit IP (30/minuto)
- Test 429 quando limite raggiunto
- Test headers X-RateLimit-* presenti
- Test reset dopo window

## 🔄 WORKFLOW TDD
Per **OGNI** task:
1. **RED**: Scrivi test che fallisce (prima del codice!)
2. **GREEN**: Implementa codice minimo per passare il test
3. **REFACTOR**: Migliora codice, test rimangono verdi

## 🧪 ESEMPI TEST
### Test Dependency API Token
```python
@pytest.mark.asyncio
async def test_get_current_user_from_api_token_valid_returns_user(db_session, test_user):
# Arrange
token, token_hash = generate_api_token()
api_token = ApiToken(user_id=test_user.id, token_hash=token_hash, name="Test")
db_session.add(api_token)
db_session.commit()
# Act
user = await get_current_user_from_api_token(token, db_session)
# Assert
assert user.id == test_user.id
```
### Test Endpoint Stats
```python
def test_public_stats_with_valid_token_returns_200(client, api_token):
response = client.get(
"/api/v1/stats",
headers={"Authorization": f"Bearer {api_token}"}
)
assert response.status_code == 200
assert "summary" in response.json()
```
### Test Rate Limiting
```python
def test_rate_limit_429_after_100_requests(client, api_token):
# Make 100 requests
for _ in range(100):
response = client.get("/api/v1/stats", headers={"Authorization": f"Bearer {api_token}"})
assert response.status_code == 200
# 101st request should fail
response = client.get("/api/v1/stats", headers={"Authorization": f"Bearer {api_token}"})
assert response.status_code == 429
```

## 📋 DIFFERENZE CHIAVE: API Pubblica vs Web API
| Feature | Web API (/api/auth, /api/keys) | API Pubblica (/api/v1/*) |
|---------|--------------------------------|--------------------------|
| **Auth** | JWT Bearer | API Token Bearer |
| **Scopo** | Gestione (CRUD) | Lettura dati |
| **Rate Limit** | No (o diverso) | Sì (100/ora) |
| **Audience** | Frontend web | Integrazioni esterne |
| **Token TTL** | 24 ore | Illimitato (fino a revoca) |
---
## 🔒 CONSIDERAZIONI SICUREZZA
### Do's ✅
- Verificare sempre API token con hash in database
- Aggiornare `last_used_at` ad ogni richiesta
- Rate limiting per prevenire abusi
- Non esporre mai API key values (cifrate)
- Validare date (max range 365 giorni)
### Don'ts ❌
- MAI accettare JWT su API pubblica
- MAI loggare API token in plaintext
- MAI ritornare dati di altri utenti
- MAI bypassare rate limiting
- MAI permettere range date > 365 giorni
---
## 📝 NOTE IMPORTANTI
- **Path assoluti**: Usa sempre `/home/google/Sources/LucaSacchiNet/openrouter-watcher/`
- **Dependency**: Crea `get_current_user_from_api_token()` separata da `get_current_user()`
- **Rate limiting**: In-memory per MVP, Redis per produzione
- **Token format**: API token inizia con `or_api_`, JWT no
- **last_used_at**: Aggiornare ad ogni chiamata API pubblica
---
**AGENTE:** @tdd-developer
**INIZIA CON:** T35 - Pydantic public API schemas
**QUANDO FINITO:** Conferma completamento, coverage >= 90%, aggiorna progress.md
