# Premiers pas avec gRPC

Premiers pas avec l’API gRPC de KiloCenter — vérifiez la connectivité locale au port 9090 de KC-Core avec grpcurl, listez les services.

### Objectif

Vérifiez la connectivité gRPC locale vers KC-Core et découvrez les méthodes d’API disponibles.

### Vérifier l’accessibilité du service

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

### Inspecter le service principal

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

### Vérifier le service de santé gRPC

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

### Appeler une méthode d’API de base

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

### Authentification et contexte de l’organisation

L’édition Community fonctionne avec l’authentification désactivée par défaut en mode développement. Les commandes gRPC ci-dessus fonctionnent sans en-têtes d’authentification dans cette configuration.

Si vous activez l’authentification (édition Enterprise ou en définissant `KILOCENTER_AUTH_ENABLED=true`), incluez des en-têtes de métadonnées dans les appels gRPC :

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

### Étape suivante

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-fr/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.
