+# ChatGPT-to-API
+Create a fake API using ChatGPT's website
+
+**API endpoint: http://127.0.0.1:8080/v1/chat/completions.**
+
+**When calling the API, you must include the authorization parameter in the request header: `'Authorization':'Bearer ' + accessToken`.**
+
+**You can get your accessToken from the following link: [ChatGPT](https://chat.openai.com/api/auth/session)**
+
+**This API can be used with the project [BetterChatGPT](https://github.com/huangzt/BetterChatGPT)**
+
+## Docker build & Run
+
+```bash
+docker build -t chatgpt-to-api .
+
+# Running the API
+docker run --name chatgpttoapi -d -p 127.0.0.1:8080:8080 chatgpt-to-api
+
+# API path
+http://127.0.0.1:8080/v1/chat/completions
