我有一个API路由在我的数据库中生成数据，该API路由仅在Vercel中的CRON作业集中调用。
但是，每次我构建项目时，数据库中都会显示新数据。我相信这是因为NextJS的性质，预执行一个端点，所以它将有缓存，但我如何防止在我的数据库中添加数据？

代码很简单：https://github.com/guifeliper/dart-throwing-monkey-crypto/blob/main/apps/monkey-crypto/app/api/generateTokens/route.ts

export const revalidate = 60 * 60 * 24 * 6; // every 6 days
export async function GET(request: Request) {
  const url =
    `${process.env.COINMARKETCAP_URL}/v1/cryptocurrency/listings/latest?limit=100` ??
    "";
  var options = {
    headers: {
      "X-CMC_PRO_API_KEY": process.env.COINMARKETCAP_API ?? "",
    },
    next: { revalidate: 60 * 60 * 24 * 6 },
  };

  const res = await fetch(url, options);
  const data = await res.json();

  const tokensList: Tokens[] =
    data?.data?.map((token: any) => {
      return {
        name: token.name,
        symbol: token.symbol,
        priceAtDrawn: token.quote["USD"].price,
        priceAtContest: 0,
        category: "Top-100",
        timeframe: getYearWeekString(),
      };
    }) ?? [];

  const BTCBenchmark = tokensList
    .filter((token) => token.symbol === "BTC")
    .map((token) => ({ ...token, category: "BTC-benchmark" }));

  if (tokensList?.length == 0) {
    return NextResponse.json(
      { message: "Error on token list" },
      { status: 500 }
    );
  }
  const selectedTokens = selectTokens(tokensList, 10);
  return await addTokensDrawn([...selectedTokens, ...BTCBenchmark]);
}

async function addTokensDrawn(data: any) {
  try {
    await prisma.tokenDrawn.createMany({ data });
    return NextResponse.json({ message: "Add Successfully" }, { status: 200 });
  } catch (error) {
    console.error("Request error", error);
    return NextResponse.json({ message: "Error on add" }, { status: 500 });
  }
}
