/// warning

When you return a `Response` directly, like in the example above, it will be returned directly.

It won't be serialized with a model, etc.

Make sure it has the data you want it to have, and that the values are valid JSON (if you are using `JSONResponse`).

## Pydantic моделі { #pydantic-models }

[Pydantic](https://docs.pydantic.dev/) — це бібліотека Python для валідації даних.

Ви оголошуєте «форму» даних як класи з атрибутами.

І кожен атрибут має тип.

# 宣告請求範例資料 { #declare-request-example-data }

你可以宣告你的應用程式可接收資料的 examples。

以下有數種方式可達成。

## Pydantic 模型中的額外 JSON Schema 資料 { #extra-json-schema-data-in-pydantic-models }

你可以為 Pydantic 模型宣告 `examples`，它們會加入到產生出的 JSON Schema 中。

{* ../../docs_src/schema_extra_example/tutorial001_py310.py hl[13:24] *}

這些額外資訊會原封不動加入該模型輸出的 JSON Schema，並且會用在 API 文件裡。

[Prometheus](https://prometheus.io) is a cloud-native monitoring platform. Prometheus offers a multi-dimensional data model with time series data identified by metric name and key/value pairs. The data collection happens via a pull model over HTTP/HTTPS. Users looking to monitor their MinIO instances can point Prometheus configuration to scrape data from following endpoints. 

Many packages that simplify it a lot have to make many compromises with the data model, database, and available features. And some of these packages that simplify things too much actually have security flaws underneath.

---

**FastAPI** doesn't make any compromise with any database, data model or tool.

It gives you all the flexibility to choose the ones that fit your project the best.
