Cron & Scheduler

\n

Die Cron-API ermöglicht das Planen wiederkehrender HTTP-Aufrufe an Synapse-\nEndpunkte (oder externe HTTPS-Endpunkte). Perfekt für periodischen Sync,\nErinnerungen und Wartungsaufgaben.

\n

Endpunkte

\n

POST /cron

\n

Einen geplanten Task anlegen.

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

Antwort:

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

GET /cron

\n

Alle geplanten Tasks auflisten.

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

DELETE /cron/:id

\n

Einen geplanten Task löschen.

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

PUT /cron/:id/toggle

\n

Einen Task aktivieren oder deaktivieren, ohne ihn zu löschen.

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

Schedule-Syntax

\n

Standard-Cron (5 Felder)

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

Beispiele:

\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
ScheduleBedeutung
0 * * * *Jede Stunde
*/15 * * * *Alle 15 Minuten
0 9 * * 1-5Werktags um 9 Uhr
0 0 * * 0Jeden Sonntag um Mitternacht
0 0 1 * *Ersten jeden Monats um Mitternacht
\n

Integer-Intervall (Sekunden)

\n

Für einfache Intervalle übergibst du einen Integer:

\n
{ "schedule": "300" }  // Alle 5 Minuten

Endpunkt-Einschränkungen

\n
Endpoints must be `http://` or `https://` URLs pointing to:

Das verhindert SSRF-Angriffe, bei denen ein kompromittierter Mind Anfragen an\ninterne Dienste planen könnte.

\n

Häufige Patterns

\n

Stündlicher Memory-Recall (für LLM-Agenten)

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

Tägliche Sicherung

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

Periodischer Chat-Poll (alle 5 Minuten)

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

Wöchentlicher Report-Trigger

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