description: Send your Vercel request logs to a Sommet drain URL to count ChatGPT, Gemini, Claude, Perplexity, Copilot and other AI bot visits in near real time.
---

Vercel can push the logs of your projects to an HTTP endpoint, called a drain. Sommet gives you a secret drain URL and counts the AI bot requests in each delivery.

Drains are available on the Vercel **Pro** and **Enterprise** plans. On Hobby, put the [Cloudflare proxy](/docs/ai-bots/cloudflare) in front of your site, or use a [custom drain](/docs/ai-bots/custom) from your app.

## Connect

1. **Start a drain in Vercel**

    Open your team in Vercel, then **Settings → Drains → Add Drain** and choose **Logs**.

    - **Projects:** the project that serves your domain.
    - **Sources:** the ones that serve requests: static files, functions and middleware. Leave out builds.
    - **Environments:** Production.
    - **Sampling rate:** 100 %. A lower rate lowers the counts by the same ratio.

    Choose a custom HTTP endpoint as the destination. Vercel shows a **verification code**. Copy it and keep this tab open.

2. **Create the drain URL in Sommet**

    In Sommet, open **Settings → AI bot visits**, choose **Vercel** and paste the verification code. Select **Create a drain URL**, then copy the **Drain URL**.

3. **Finish the drain in Vercel**

    Paste the drain URL as the endpoint. Choose **JSON** or **NDJSON** as the format and leave compression off. Vercel calls the URL to verify it: Sommet answers with your verification code in the `x-vercel-verify` header.

The overview shows "Last logs received" after the first delivery. A delivery arrives every few seconds to every few minutes, depending on your traffic.

## Notes

- Vercel can log one request several times, once per runtime that served it. Sommet counts each request ID once.
- Vercel retries failed deliveries. Sommet drops a request ID it already counted in the last 6 hours.
- If you change the verification code, paste the new one in **Change source** and select **Save**. The drain URL stays the same.
- Switching between Vercel and a custom drain keeps the same URL. Switching to Cloudflare deletes it.

:::warning
The drain URL is the only credential. Anyone who has it can send logs to your workspace. Do not commit it to a public repository. To rotate it, disconnect the source and connect it again.
