### Get Conversation by ID (Go)

Source: https://docs.sindarin.tech/conversations/GET--conversationId-

Demonstrates how to fetch conversation details using Go. This code snippet utilizes the `net/http` package to make a GET request to the Sindarin API, passing the conversation ID and API key. It handles potential errors and decodes the JSON response into a struct.

```go
package main

import (
	"encoding/json"
	"fmt"
	"io/ioutil"
	"net/http"
	"time"
)

type ConversationResponse struct {
	Cost     float64    `json:"cost"`
	Messages []struct{} `json:"messages"`
	Status   string     `json:"status"`
	Duration int        `json:"duration"`
}

func getConversationById(conversationId string, apiKey string) (*ConversationResponse, error) {
	client := http.Client{
		Timeout: time.Second * 10, // Set a timeout
	}

	url := fmt.Sprintf("https://api.sindarin.tech/v1/conversations/%s", conversationId)

	req, err := http.NewRequest("GET", url, nil)
	if err != nil {
		return nil, fmt.Errorf("failed to create request: %w", err)
	}

	req.Header.Set("x-api-key", apiKey)

	res, err := client.Do(req)
	if err != nil {
		return nil, fmt.Errorf("failed to execute request: %w", err)
	}
	defer res.Body.Close()

	body, err := ioutil.ReadAll(res.Body)
	if err != nil {
		return nil, fmt.Errorf("failed to read response body: %w", err)
	}

	if res.StatusCode < 200 || res.StatusCode >= 300 {
		return nil, fmt.Errorf("API returned non-success status code: %d, body: %s", res.StatusCode, string(body))
	}

	var conversationData ConversationResponse
	err = json.Unmarshal(body, &conversationData)
	if err != nil {
		return nil, fmt.Errorf("failed to unmarshal JSON response: %w", err)
	}

	return &conversationData, nil
}

// Example usage:
// func main() {
// 	conversationID := "some-conversation-id"
// 	apiKey := "your-api-key"
// 	data, err := getConversationById(conversationID, apiKey)
// 	if err != nil {
// 		fmt.Printf("Error: %v\n", err)
// 		return
// 	}
// 	fmt.Printf("Conversation Data: %+v\n", data)
// }
