Prerequisites

​
Creating a bun server

1

Install

For bun’s installation, refer to their documentation

Now install the @unkey/api package

bun install @unkey/api
2

Creating the server

Create a file called server.ts and add the following code

server.ts
import { verifyKey } from "@unkey/api";

Bun.serve({
  async fetch(req) {
    const key = req.headers.get("Authorization")?.replace("Bearer ", "");
    if (!key) {
      return new Response("Unauthorized", { status: 401 });
    }

    const { result, error } = await verifyKey(key);
    if (error) {
      // This may happen on network errors
      // We already retry the request 5 times, but if it still fails, we return an error
      console.error(error);
      return Response.json("Internal Server Error", { status: 500 });
    }

    if (!result.valid) {
      return new Response("Unauthorized", { status: 401 });
    }

    return Response.json(result);
  },
  port: 8000,
});

Running the server

bun run server.ts

Try it out

Go to https://app.unkey.com and create a new key. Then verify it with our new server:

curl http://localhost:8000 -H "Authorization: Bearer <KEY>"

It should return { "valid": true } and potentially more information about the key, depending on what you set up in the dashboard.
