### Links and references

- Never modify link syntax like `{.internal-link target=_blank}`.
- Keep markdown link structure intact: `[text](url){.internal-link}`.

### Preferred translations / glossary

Do not translate technical terms like path, route, request, response, query, body, cookie, and header, keep them as is.

When implementing the callback yourself, you could use something like [HTTPX](https://www.python-httpx.org) or [Requests](https://requests.readthedocs.io/).

This code won't be executed in your app, we only need it to *document* how that *external API* should look like.

Notice that `response_model` is a parameter of the "decorator" method (`get`, `post`, etc). Not of your *path operation function*, like all the parameters and body.

///

`response_model` receives the same type you would declare for a Pydantic model field, so, it can be a Pydantic model, but it can also be, e.g. a `list` of Pydantic models, like `List[Item]`.

```toml
[tool.fastapi]
entrypoint = "app.main:app"
```

that is equivalent to importing like:

```python
from app.main import app
```

That way the `fastapi` command will know where to find your app.

/// Note

You could also pass the path to the command, like:

```console
$ fastapi dev app/main.py
```

And be compatible with all of them at the same time.
