Delete a discovery and its associated URLs.

Polling for completion

Since discovery runs asynchronously, poll until status is completed or failed:

async function waitForDiscovery(discoveryId) {
  while (true) {
    const response = await fetch(
      `https://api.meter.sh/discover/${discoveryId}`,
      {
        headers: {
          Authorization: `Bearer ${process.env.METER_API_KEY}`,
        },
      }
    );

    const discovery = await response.json();

    if (discovery.status === "completed") {
      return discovery;
    } else if (discovery.status === "failed") {
      throw new Error(discovery.errors.join(", "));
    }

    // Wait 2 seconds before next check
    await new Promise((resolve) => setTimeout(resolve, 2000));
  }
}

Error responses
