# Update December 11, 2022
Today, OpenAI added additional Cloudflare protections that make it more difficult to access the unofficial API. _This is affecting all ChatGPT API wrappers at the moment_, including the Python ones. See [this issue](https://github.com/transitive-bullshit/chatgpt-api/issues/96).
**As a temporary workaround**, make sure you're using the latest version of this package and Node.js >= 18:
1. Log into https://chat.openai.com/chat and copy a fresh session token (same instructions as below).
2. Copy the value of the `cf_clearance` cookie and store it in a `CLEARANCE_TOKEN` environment variable in addition to your `SESSION_TOKEN`.
3. Copy your browser's `user-agent` header from any request in your browser's network tab.
4. Use both tokens when creating the API wrapper:
```ts
const api = new ChatGPTApI({
sessionToken: process.env.SESSION_TOKEN,
clearanceToken: process.env.CLEARANCE_TOKEN,
userAgent: '' // replace to match your real browser's user agent
})
await api.ensureAuth()
```
Restrictions on this method:
- Cloudflare `cf_clearance` **tokens expire after 2 hours**, so right now you'll have to manually log in and extract it by hand every so often
- Your `user-agent` and `IP address` **must match** from the real browser window you're logged in with to the one you're using for `ChatGPTAPI`.
- This means that you currently can't log in with your laptop and then run the bot on a server or proxy somewhere.
- You must use `node >= 18`. I'm using `v19.2.0` in my testing, but for some reason, all `fetch` requests using Node.js `v16` and `v17` fail at the moment (these use `undici` under the hood, whereas Node.js v18 and above use a built-in `fetch` based on `undici`).
- You should not be using this account while the bot is using it, because that browser window may refresh one of your tokens and invalidate the bot's session.
We're working hard in [this issue](https://github.com/transitive-bullshit/chatgpt-api/issues/96) to make this process easier and more automated.
Cheers,
Travis

## Intro
This package is a Node.js wrapper around [ChatGPT](https://openai.com/blog/chatgpt) by [OpenAI](https://openai.com). TS batteries included. ✨
You can use it to start building projects powered by ChatGPT like chatbots, websites, etc...
## Install
```bash
npm install chatgpt
```
## Usage
```ts
import { ChatGPTAPI } from 'chatgpt'
async function example() {
// sessionToken is required; see below for details
const api = new ChatGPTAPI({
sessionToken: process.env.SESSION_TOKEN
})
// ensure the API is properly authenticated
await api.ensureAuth()
// send a message and wait for the response
const response = await api.sendMessage(
'Write a python version of bubble sort.'
)
// response is a markdown-formatted string
console.log(response)
}
```
ChatGPT responses are formatted as markdown by default. If you want to work with plaintext instead, you can use:
```ts
const api = new ChatGPTAPI({
sessionToken: process.env.SESSION_TOKEN,
markdown: false
})
```
If you want to automatically track the conversation, you can use `ChatGPTAPI.getConversation()`:
```ts
const api = new ChatGPTAPI({
sessionToken: process.env.SESSION_TOKEN
})
const conversation = api.getConversation()
// send a message and wait for the response
const response0 = await conversation.sendMessage('What is OpenAI?')
// send a follow-up prompt to the previous message and wait for the response
const response1 = await conversation.sendMessage('Can you expand on that?')
// send another follow-up to the same conversation
const response2 = await conversation.sendMessage('Oh cool; thank you')
```
Sometimes, ChatGPT will hang for an extended period of time before beginning to respond. This may be due to rate limiting or it may be due to OpenAI's servers being overloaded.
To mitigate these issues, you can add a timeout like this:
```ts
// timeout after 2 minutes (which will also abort the underlying HTTP request)
const response = await api.sendMessage('this is a timeout test', {
timeoutMs: 2 * 60 * 1000
})
```
You can stream responses using the `onProgress` or `onConversationResponse` callbacks. See the [docs](./docs/classes/ChatGPTAPI.md) for more details.

<summary>Usage in CommonJS (Dynamic import)</summary>
```js
async function example() {
// To use ESM in CommonJS, you can use a dynamic import
const { ChatGPTAPI } = await import('chatgpt')
const api = new ChatGPTAPI({
sessionToken: process.env.SESSION_TOKEN
})
await api.ensureAuth()
const response = await api.sendMessage('Hello World!')
console.log(response)
}
```
</details>
### Docs
See the [auto-generated docs](./docs/classes/ChatGPTAPI.md) for more info on methods and parameters.
### Demos
A [basic demo](./src/demo.ts) is included for testing purposes:
```bash
# 1. clone repo
# 2. install node deps
# 3. set `SESSION_TOKEN` in .env
# 4. run:
npx tsx src/demo.ts
```
A [conversation demo](./src/demo-conversation.ts) is also included:
```bash
# 1. clone repo
# 2. install node deps
# 3. set `SESSION_TOKEN` in .env
# 4. run:
npx tsx src/demo-conversation.ts
```
### Session Tokens
**This package requires a valid session token from ChatGPT to access it's unofficial REST API.**
To get a session token:
1. Go to https://chat.openai.com/chat and log in or sign up.
2. Open dev tools.
3. Open `Application` > `Cookies`.

4. Copy the value for `__Secure-next-auth.session-token` and save it to your environment.
If you want to run the built-in demo, store this value as `SESSION_TOKEN` in a local `.env` file.
> **Note**
> This package will switch to using the official API once it's released.
> **Note**
> Prior to v1.0.0, this package used a headless browser via [Playwright](https://playwright.dev/) to automate the web UI. Here are the [docs for the initial browser version](https://github.com/transitive-bullshit/chatgpt-api/tree/v0.4.2).

## Compatibility
This package is ESM-only. It supports:
- Node.js >= 16.8
- If you need Node.js 14 support, use [`v1.4.0`](https://github.com/transitive-bullshit/chatgpt-api/releases/tag/v1.4.0)
- Edge runtimes like CF workers and Vercel edge functions
- Modern browsers
- Mainly meant for chrome extensions where your code is protected to a degree
- We recommend against using `chatgpt` from client-side browser code because it would expose your private session token
- If you want to build a website using `chatgpt`, we recommend using it only from your backend API
