API returning 500 server error

export const prerender = false;

export async function GET() {
  const apiKey = import.meta.env.DATABUDDY_API_KEY;
  const websiteId = import.meta.env.DATABUDDY_WEBSITE_ID;

  if (!apiKey || !websiteId) {
    return new Response(
      JSON.stringify({ error: "Missing API credentials" }), 
      { status: 500, headers: { "Content-Type": "application/json" } }
    );
  }

  try {
    const response = await fetch(`https://api.databuddy.cc/v1/websites/${websiteId}/stats?period=30d`, {
      method: 'GET',
      headers: {
        'Authorization': `Bearer ${apiKey}`,
        'Content-Type': 'application/json',
      },
    });

    if (!response.ok) {
      throw new Error('Failed to fetch stats from Databuddy');
    }

    const data = await response.json();
    
    return new Response(
      JSON.stringify({ pageviews: data.pageviews || 0 }), 
      {
        status: 200,
        headers: {
          "Content-Type": "application/json",
          "Cache-Control": "public, max-age=86400, stale-while-revalidate=43200",
        },
      }
    );
  } catch (error) {
    const message = error instanceof Error ? error.message : "An unexpected error occurred";
    return new Response(
      JSON.stringify({ error: message }), 
      { status: 500, headers: { "Content-Type": "application/json" } }
    );
  }
}

this is my API fetch and its returning a 500 server error

Start by locating the API route containing the GET handler shown in the issue and run it with the relevant environment variables configured. Check the server response and the Databuddy stats request to identify which step produces the 500 error. Done means the endpoint no longer returns an unexpected 500 for a valid configuration and its error behavior is covered or documented.
