# Primeiros Passos com gRPC

Primeiros passos com a API gRPC do KiloCenter — verifique a conectividade local à porta 9090 do KC-Core com grpcurl e liste os serviços.

### Objetivo

Verifique a conectividade gRPC local com o KC-Core e descubra os métodos de API disponíveis.

### Verificar alcance do serviço

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

### Inspecionar o serviço principal

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

### Verificar o serviço de saúde do gRPC

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

### Chamar um método básico da API

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

### Autenticação e contexto da organização

A Edição Comunitária é executada com a autenticação desativada por padrão no modo de desenvolvimento. Os comandos gRPC acima funcionam sem cabeçalhos de autenticação nessa configuração.

Se você ativar a autenticação (Edição Enterprise ou ao definir `KILOCENTER_AUTH_ENABLED=true`), inclua cabeçalhos de metadados nas chamadas gRPC:

```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-pt/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.
