+## [FastAPI](https://fastapi.tiangolo.com/#installation)
+
+FastAPI is a web framework to build APIs. It needs the ASGI server like [uvicorn](https://www.uvicorn.org/).
+
+```sh
+uvicorn fastapi_main:app --reload
+```
+
+* Some URLs
+
+```sh
+http://127.0.0.1:8000/docs
+http://127.0.0.1:8000/redoc
+```
