### Basic Usage

Here's a quick example of how to use the Chalk Go client:

```
package main

import (
    "context"
    "fmt"
    "log"

    "github.com/chalk-ai/chalk-go"
)

func main() {
    // Initialize the client
    client, err := chalk.NewClient(
        chalk.WithClientID("your-client-id"),
        chalk.WithClientSecret("your-client-secret"),
        chalk.WithEnvironment("your-environment-id"),
    )
    if err != nil {
        log.Fatal(err)
    }

    // Query features
    result, err := client.Query(context.Background(), chalk.QueryParams{
        Inputs: map[string]interface{}{
            "user.id": "user123",
        },
        Outputs: []string{
            "user.credit_score",
            "user.account_age_days",
        },
    })
    if err != nil {
        log.Fatal(err)
    }

    fmt.Println(result)
}
```
