For example, it was clear that ideally it should be based on standard Python type hints.

Also, the best approach was to use already existing standards.

So, before even starting to code **FastAPI**, I spent several months studying the specs for OpenAPI, JSON Schema, OAuth2, etc. Understanding their relationship, overlap, and differences.

### Just Modern Python { #just-modern-python }

It's all based on standard **Python type** declarations (thanks to Pydantic). No new syntax to learn. Just standard modern Python.

If you need a 2 minute refresher of how to use Python types (even if you don't use FastAPI), check the short tutorial: [Python Types](python-types.md).

You write standard Python with types:

```Python
from datetime import date

## Consequences

* X
* Y
* Z
```

## Consequences

* We start to use Architectural Decision Records
* We use the proposed template from this ADR
* We locate `.md` files in the folder `/architecture/standards`
* We highly encourage usage of ADR to communicate decisions

FastAPI Cloud is the primary sponsor and funding provider for the *FastAPI and friends* open source projects. ✨

## Deploy to other cloud providers { #deploy-to-other-cloud-providers }

FastAPI is open source and based on standards. You can deploy FastAPI apps to any cloud provider you choose.

Follow your cloud provider's guides to deploy FastAPI apps with them. 🤓

# Policy on AI-Assisted Contributions to the Gradle Build Tool

We use AI tools daily and welcome AI-assisted contributions—provided the human behind them meets the standards below.

## Why this policy exists

There is a fundamental **asymmetry** between submitting a contribution and reviewing one: AI tools make it easy to generate and submit large amounts of code, but they do not make it equally faster for us to review it. 

Notice that the path parameter is declared to be an integer.

## Standards-based benefits, alternative documentation { #standards-based-benefits-alternative-documentation }

And because the generated schema is from the [OpenAPI](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md) standard, there are many compatible tools.

## Abhängigkeiten { #dependencies }

FastAPI hängt von Pydantic und Starlette ab.

### `standard`-Abhängigkeiten { #standard-dependencies }

Wenn Sie FastAPI mit `pip install "fastapi[standard]"` installieren, kommt es mit der `standard`-Gruppe optionaler Abhängigkeiten:

Verwendet von Pydantic:

## Dependencies { #dependencies }

FastAPI depends on Pydantic and Starlette.

### `standard` Dependencies { #standard-dependencies }

When you install FastAPI with `pip install "fastapi[standard]"` it comes with the `standard` group of optional dependencies:

Used by Pydantic:

* [`email-validator`](https://github.com/JoshData/python-email-validator) - for email validation.

And you can use and implement secure, standard protocols, like OAuth2 in a relatively simple way.
