# Cron y Scheduler

La API de Cron permite programar llamadas HTTP recurrentes a endpoints de
Synapse (o a endpoints HTTPS externos). Ideal para sincronización periódica,
recordatorios y tareas de mantenimiento.

## Endpoints

### POST /cron

Crea una tarea programada.

```bash
curl -X POST https://synapse.schaefer.zone/cron \
  -H "Authorization: Bearer YOUR_MIND_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "schedule": "0 * * * *",
    "endpoint": "https://synapse.schaefer.zone/memory/recall",
    "method": "GET",
    "headers": {"Authorization": "Bearer YOUR_MIND_KEY"}
  }'
```

Respuesta:

```json
{
  "id": "cron_001",
  "schedule": "0 * * * *",
  "endpoint": "https://synapse.schaefer.zone/memory/recall",
  "method": "GET",
  "enabled": true,
  "next_run": "2026-06-27T13:00:00Z",
  "created_at": "2026-06-27T..."
}
```

### GET /cron

Lista todas las tareas programadas.

```bash
curl -H "Authorization: Bearer YOUR_MIND_KEY" \
     https://synapse.schaefer.zone/cron
```

### DELETE /cron/:id

Elimina una tarea programada.

```bash
curl -X DELETE -H "Authorization: Bearer YOUR_MIND_KEY" \
     https://synapse.schaefer.zone/cron/cron_001
```

### PUT /cron/:id/toggle

Habilita o deshabilita una tarea sin eliminarla.

```bash
curl -X PUT -H "Authorization: Bearer YOUR_MIND_KEY" \
     https://synapse.schaefer.zone/cron/cron_001/toggle
```

## Sintaxis de programación

### Cron estándar (5 campos)

```
┌───── minute (0-59)
│ ┌───── hour (0-23)
│ │ ┌───── day of month (1-31)
│ │ │ ┌───── month (1-12)
│ │ │ │ ┌───── day of week (0-6, 0=Sunday)
│ │ │ │ │
* * * * *
```

Ejemplos:

| Programación | Significado |
|----------|---------|
| `0 * * * *` | Cada hora |
| `*/15 * * * *` | Cada 15 minutos |
| `0 9 * * 1-5` | Días laborables a las 9am |
| `0 0 * * 0` | Cada domingo a medianoche |
| `0 0 1 * *` | El primero de cada mes a medianoche |

### Intervalo entero (segundos)

Para intervalos simples, pase un entero:

```json
{ "schedule": "300" }  // Every 5 minutes
```

## Restricciones de endpoints

> [!WARNING]
> Los endpoints deben ser URLs `http://` o `https://` que apunten a:
> - La misma instancia de Synapse (p. ej. `http://synapse:12800/memory/recall`)
> - URLs HTTPS públicas (no IPs privadas, no localhost, no IPs de metadata)

Esto evita ataques SSRF donde un mind comprometido podría programar peticiones
a servicios internos.

## Patrones comunes

### Recall de memoria cada hora (para agentes LLM)

```bash
curl -X POST .../cron -d '{
  "schedule": "0 * * * *",
  "endpoint": "https://synapse.schaefer.zone/memory/recall",
  "method": "GET",
  "headers": {"Authorization": "Bearer YOUR_MIND_KEY"}
}'
```

### Backup diario

```bash
curl -X POST .../cron -d '{
  "schedule": "0 2 * * *",
  "endpoint": "https://synapse.schaefer.zone/memory/mind-export",
  "method": "GET",
  "headers": {"Authorization": "Bearer YOUR_MIND_KEY"}
}'
```

### Poll periódico de chat (cada 5 minutos)

```bash
curl -X POST .../cron -d '{
  "schedule": "300",
  "endpoint": "https://synapse.schaefer.zone/chat/poll",
  "method": "GET",
  "headers": {"Authorization": "Bearer YOUR_MIND_KEY"}
}'
```

### Disparador de reporte semanal

```bash
curl -X POST .../cron -d '{
  "schedule": "0 9 * * 1",
  "endpoint": "https://my-app.com/weekly-report",
  "method": "POST",
  "body": "{\"mind_id\": \"m_xyz789\"}",
  "headers": {"Content-Type": "application/json", "X-API-Key": "my-secret"}
}'
```
