## Ejemplo
|
|
|
|
```go
|
|
result, err := HttpGetJSON(
|
|
"https://api.example.com/users",
|
|
map[string]string{"X-Api-Key": "secret"},
|
|
10*time.Second,
|
|
)
|
|
if err != nil {
|
|
return nil, err
|
|
}
|
|
fmt.Println(result["total"])
|
|
```

## Notas
|
|
|
|
Solo usa stdlib (net/http, encoding/json). El timeout se configura en el http.Client. El error incluye los primeros 200 bytes del body para facilitar debugging. Los headers custom se fusionan con Accept: application/json (custom tiene precedencia).
