# gRPC-Erste Schritte

Erste Schritte mit der KiloCenter-gRPC-API — lokale Verbindung zu KC-Core auf Port 9090 mit grpcurl überprüfen, Dienste auflisten.

### Ziel

Lokale gRPC-Konnektivität zu KC-Core überprüfen und verfügbare API-Methoden entdecken.

### Erreichbarkeit des Dienstes prüfen

```bash
grpcurl -plaintext localhost:9090 list
```

### Hauptdienst prüfen

```bash
grpcurl -plaintext localhost:9090 describe kilocenter.api.v1.KiloCenterService
```

### gRPC-Health-Service prüfen

```bash
grpcurl -plaintext localhost:9090 grpc.health.v1.Health/Check
```

### Eine grundlegende API-Methode aufrufen

```bash
grpcurl -plaintext -d '{}' \
  localhost:9090 kilocenter.api.v1.KiloCenterService/GetSystemStatus
```

### Authentifizierungs- und Organisationskontext

Die Community Edition läuft im Entwicklungsmodus standardmäßig mit deaktivierter Authentifizierung. Die obigen gRPC-Befehle funktionieren in dieser Konfiguration ohne Auth-Header.

Wenn Sie die Authentifizierung aktivieren (Enterprise Edition oder durch Setzen von `KILOCENTER_AUTH_ENABLED=true`), fügen Sie Metadaten-Header in gRPC-Aufrufe ein:

```bash
grpcurl -plaintext \
  -H "authorization: Bearer <JWT_TOKEN>" \
  -H "x-organization-id: <ORG_ID>" \
  -d '{}' \
  localhost:9090 kilocenter.api.v1.KiloCenterService/GetSystemStatus
```

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.kiloiot.io/kilo-docs-de/kilo-center/kilo-mioty-service-center/integrations/grpc-first-steps.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
