## How to tell a real GPTBot from an impostor

Anyone can put "GPTBot" in a user agent. What can't be faked is below.

- **Check the address.** OpenAI publishes the IP ranges GPTBot uses: [openai.com/gptbot.json](https://openai.com/gptbot.json). A request whose user agent says GPTBot from an address outside them is an impostor.

## How Punchline counts GPTBot

Punchline labels a request that names GPTBot with how sure it is: **verified** or **declared** when the evidence checks out, a lower tier when it can't be checked, and **impostor** when the evidence contradicts it. Each visit is counted under OpenAI, with its purpose, so you can see whether GPTBot is reading your site and which pages it reads.
