* Serialization: you could return an arbitrary object and the

be a Pydantic model, it could be other things, like a `list`, `dict`,
etc.
It will be used for:
* Documentation: the generated OpenAPI (and the UI at `/docs`) will
show it as the response (JSON Schema).
* Serialization: you could return an arbitrary object and the
`response_model` would be used to serialize that object into the
corresponding JSON.
* Filtering: the JSON sent to the client will only contain the data
(fields) defined in the `response_model`. If you returned an object
that contains an attribute `password` but the `response_model` does
not include that field, the JSON sent to the client would not have
that `password`.
* Validation: whatever you return will be serialized with the
`response_model`, converting any data as necessary to generate the
corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an
error and return a 500 error code (Internal Server Error).

It could be any valid Pydantic *field* type. So, it doesn't have to

* Documentation: the generated OpenAPI (and the UI at `/docs`) will

* Serialization: you could return an arbitrary object and the

corresponding JSON.
* Filtering: the JSON sent to the client will only contain the data

that contains an attribute `password` but the `response_model` does
not include that field, the JSON sent to the client would not have
that `password`.

* Documentation: the generated OpenAPI (and the UI at `/docs`) will
show it as the response (JSON Schema).
* Serialization: you could return an arbitrary object and the
`response_model` would be used to serialize that object into the
corresponding JSON.
* Filtering: the JSON sent to the client will only contain the data
(fields) defined in the `response_model`. If you returned an object
that contains an attribute `password` but the `response_model` does
not include that field, the JSON sent to the client would not have
that `password`.
* Validation: whatever you return will be serialized with the
`response_model`, converting any data as necessary to generate the
corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an

The type to use for the response.
It could be any valid Pydantic *field* type. So, it doesn't have to
be a Pydantic model, it could be other things, like a `list`, `dict`,
etc.
It will be used for:
* Documentation: the generated OpenAPI (and the UI at `/docs`) will
show it as the response (JSON Schema).
* Serialization: you could return an arbitrary object and the
`response_model` would be used to serialize that object into the
corresponding JSON.
* Filtering: the JSON sent to the client will only contain the data
(fields) defined in the `response_model`. If you returned an object
that contains an attribute `password` but the `response_model` does
not include that field, the JSON sent to the client would not have
that `password`.
* Validation: whatever you return will be serialized with the
`response_model`, converting any data as necessary to generate the
corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an
error and return a 500 error code (Internal Server Error).

* Documentation: the generated OpenAPI (and the UI at `/docs`) will
show it as the response (JSON Schema).
* Serialization: you could return an arbitrary object and the
`response_model` would be used to serialize that object into the
corresponding JSON.
* Filtering: the JSON sent to the client will only contain the data
(fields) defined in the `response_model`. If you returned an object
that contains an attribute `password` but the `response_model` does
not include that field, the JSON sent to the client would not have
that `password`.
* Validation: whatever you return will be serialized with the
`response_model`, converting any data as necessary to generate the
corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an

The type to use for the response.
It could be any valid Pydantic *field* type. So, it doesn't have to

etc.
It will be used for:
* Documentation: the generated OpenAPI (and the UI at `/docs`) will
show it as the response (JSON Schema).
* Serialization: you could return an arbitrary object and the
`response_model` would be used to serialize that object into the
corresponding JSON.
* Filtering: the JSON sent to the client will only contain the data
(fields) defined in the `response_model`. If you returned an object
that contains an attribute `password` but the `response_model` does
not include that field, the JSON sent to the client would not have
that `password`.
* Validation: whatever you return will be serialized with the
`response_model`, converting any data as necessary to generate the
corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an
error and return a 500 error code (Internal Server Error).

* Documentation: the generated OpenAPI (and the UI at `/docs`) will
show it as the response (JSON Schema).
* Serialization: you could return an arbitrary object and the
`response_model` would be used to serialize that object into the
corresponding JSON.
* Filtering: the JSON sent to the client will only contain the data
(fields) defined in the `response_model`. If you returned an object
that contains an attribute `password` but the `response_model` does
not include that field, the JSON sent to the client would not have
that `password`.
* Validation: whatever you return will be serialized with the
`response_model`, converting any data as necessary to generate the
corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an

It could be any valid Pydantic *field* type. So, it doesn't have to

It will be used for:
* Documentation: the generated OpenAPI (and the UI at `/docs`) will
show it as the response (JSON Schema).
* Serialization: you could return an arbitrary object and the
`response_model` would be used to serialize that object into the
corresponding JSON.
* Filtering: the JSON sent to the client will only contain the data
(fields) defined in the `response_model`. If you returned an object
that contains an attribute `password` but the `response_model` does
not include that field, the JSON sent to the client would not have
that `password`.
* Validation: whatever you return will be serialized with the
`response_model`, converting any data as necessary to generate the
corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an
error and return a 500 error code (Internal Server Error).

* Serialization: you could return an arbitrary object and the

* Documentation: the generated OpenAPI (and the UI at `/docs`) will
show it as the response (JSON Schema).
* Serialization: you could return an arbitrary object and the
`response_model` would be used to serialize that object into the
corresponding JSON.
* Filtering: the JSON sent to the client will only contain the data
(fields) defined in the `response_model`. If you returned an object
that contains an attribute `password` but the `response_model` does
not include that field, the JSON sent to the client would not have
that `password`.
* Validation: whatever you return will be serialized with the
`response_model`, converting any data as necessary to generate the
corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an
error and return a 500 error code (Internal Server Error).

The type to use for the response.
It could be any valid Pydantic *field* type. So, it doesn't have to

It will be used for:
* Documentation: the generated OpenAPI (and the UI at `/docs`) will
show it as the response (JSON Schema).
* Serialization: you could return an arbitrary object and the
`response_model` would be used to serialize that object into the
corresponding JSON.
* Filtering: the JSON sent to the client will only contain the data
(fields) defined in the `response_model`. If you returned an object
that contains an attribute `password` but the `response_model` does
not include that field, the JSON sent to the client would not have
that `password`.
* Validation: whatever you return will be serialized with the
`response_model`, converting any data as necessary to generate the
corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an
error and return a 500 error code (Internal Server Error).

* Serialization: you could return an arbitrary object and the

not include that field, the JSON sent to the client would not have
that `password`.
* Validation: whatever you return will be serialized with the

corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an

* Filtering: the JSON sent to the client will only contain the data
(fields) defined in the `response_model`. If you returned an object
that contains an attribute `password` but the `response_model` does
not include that field, the JSON sent to the client would not have
that `password`.
* Validation: whatever you return will be serialized with the
`response_model`, converting any data as necessary to generate the
corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an
error and return a 500 error code(Internal Server Error).

(fields) defined in the `response_model`. If you returned an object
that contains an attribute `password` but the `response_model` does
not include that field, the JSON sent to the client would not have
that `password`.
* Validation: whatever you return will be serialized with the
`response_model`, converting any data as necessary to generate the
corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an
error and return a 500 error code(Internal Server Error).

It could be any valid Pydantic *field* type. So, it doesn't have to

It will be used for:
* Documentation: the generated OpenAPI (and the UI at `/docs`) will
show it as the response (JSON Schema).
* Serialization: you could return an arbitrary object and the
`response_model` would be used to serialize that object into the
corresponding JSON.
* Filtering: the JSON sent to the client will only contain the data
(fields) defined in the `response_model`. If you returned an object
that contains an attribute `password` but the `response_model` does
not include that field, the JSON sent to the client would not have
that `password`.
* Validation: whatever you return will be serialized with the
`response_model`, converting any data as necessary to generate the
corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an
error and return a 500 error code (Internal Server Error).

The type to use for the response.
It could be any valid Pydantic * field * type. So, it doesn't have to
be a Pydantic model, it could be other things, like a `list`, `dict`,
etc.
It will be used for:
* Documentation: the generated OpenAPI (and the UI at `/ docs`) will
show it as the response(JSON Schema).
* Serialization: you could return an arbitrary object and the
`response_model` would be used to serialize that object into the
corresponding JSON.
* Filtering: the JSON sent to the client will only contain the data
(fields) defined in the `response_model`. If you returned an object
that contains an attribute `password` but the `response_model` does
not include that field, the JSON sent to the client would not have
that `password`.
* Validation: whatever you return will be serialized with the
`response_model`, converting any data as necessary to generate the
corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an
error and return a 500 error code(Internal Server Error).

* Serialization: you could return an arbitrary object and the

not include that field, the JSON sent to the client would not have
that `password`.

corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an

The type to use for the response.
It could be any valid Pydantic *field* type. So, it doesn't have to

It will be used for:
* Documentation: the generated OpenAPI (and the UI at `/docs`) will
show it as the response (JSON Schema).
* Serialization: you could return an arbitrary object and the
`response_model` would be used to serialize that object into the
corresponding JSON.
* Filtering: the JSON sent to the client will only contain the data
(fields) defined in the `response_model`. If you returned an object
that contains an attribute `password` but the `response_model` does
not include that field, the JSON sent to the client would not have
that `password`.
* Validation: whatever you return will be serialized with the
`response_model`, converting any data as necessary to generate the
corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an
error and return a 500 error code (Internal Server Error).

* Serialization: you could return an arbitrary object and the

that `password`.

corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an

* Documentation: the generated OpenAPI (and the UI at `/docs`) will
show it as the response (JSON Schema).
* Serialization: you could return an arbitrary object and the
`response_model` would be used to serialize that object into the
corresponding JSON.
* Filtering: the JSON sent to the client will only contain the data
(fields) defined in the `response_model`. If you returned an object
that contains an attribute `password` but the `response_model` does
not include that field, the JSON sent to the client would not have
that `password`.
* Validation: whatever you return will be serialized with the
`response_model`, converting any data as necessary to generate the
corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an
error and return a 500 error code (Internal Server Error).

* Documentation: the generated OpenAPI (and the UI at `/docs`) will
show it as the response (JSON Schema).
* Serialization: you could return an arbitrary object and the
`response_model` would be used to serialize that object into the
corresponding JSON.
* Filtering: the JSON sent to the client will only contain the data
(fields) defined in the `response_model`. If you returned an object
that contains an attribute `password` but the `response_model` does
not include that field, the JSON sent to the client would not have
that `password`.
* Validation: whatever you return will be serialized with the
`response_model`, converting any data as necessary to generate the
corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an
error and return a 500 error code (Internal Server Error).

* Serialization: you could return an arbitrary object and the

* Filtering: the JSON sent to the client will only contain the data

* Documentation: the generated OpenAPI (and the UI at `/docs`) will
show it as the response (JSON Schema).
* Serialization: you could return an arbitrary object and the
`response_model` would be used to serialize that object into the
corresponding JSON.
* Filtering: the JSON sent to the client will only contain the data
(fields) defined in the `response_model`. If you returned an object
that contains an attribute `password` but the `response_model` does
not include that field, the JSON sent to the client would not have
that `password`.
* Validation: whatever you return will be serialized with the
`response_model`, converting any data as necessary to generate the
corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an

* Documentation: the generated OpenAPI (and the UI at `/docs`) will
show it as the response (JSON Schema).
* Serialization: you could return an arbitrary object and the
`response_model` would be used to serialize that object into the
corresponding JSON.
* Filtering: the JSON sent to the client will only contain the data

that contains an attribute `password` but the `response_model` does
not include that field, the JSON sent to the client would not have
that `password`.
* Validation: whatever you return will be serialized with the
`response_model`, converting any data as necessary to generate the
corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an

It could be any valid Pydantic * field * type. So, it doesn't have to

It will be used for:
* Documentation: the generated OpenAPI (and the UI at `/ docs`) will
show it as the response(JSON Schema).
* Serialization: you could return an arbitrary object and the
`response_model` would be used to serialize that object into the
corresponding JSON.
* Filtering: the JSON sent to the client will only contain the data
(fields) defined in the `response_model`. If you returned an object
that contains an attribute `password` but the `response_model` does
not include that field, the JSON sent to the client would not have
that `password`.
* Validation: whatever you return will be serialized with the
`response_model`, converting any data as necessary to generate the
corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an
error and return a 500 error code(Internal Server Error).

It could be any valid Pydantic *field* type. So, it doesn't have to

It will be used for:
* Documentation: the generated OpenAPI (and the UI at `/docs`) will
show it as the response (JSON Schema).
* Serialization: you could return an arbitrary object and the
`response_model` would be used to serialize that object into the
corresponding JSON.
* Filtering: the JSON sent to the client will only contain the data
(fields) defined in the `response_model`. If you returned an object
that contains an attribute `password` but the `response_model` does
not include that field, the JSON sent to the client would not have
that `password`.
* Validation: whatever you return will be serialized with the
`response_model`, converting any data as necessary to generate the
corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an
error and return a 500 error code (Internal Server Error).

* Documentation: the generated OpenAPI (and the UI at `/docs`) will
show it as the response (JSON Schema).
* Serialization: you could return an arbitrary object and the
`response_model` would be used to serialize that object into the
corresponding JSON.
* Filtering: the JSON sent to the client will only contain the data
(fields) defined in the `response_model`. If you returned an object
that contains an attribute `password` but the `response_model` does
not include that field, the JSON sent to the client would not have
that `password`.
* Validation: whatever you return will be serialized with the
`response_model`, converting any data as necessary to generate the
corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an

* Serialization: you could return an arbitrary object and the
`response_model` would be used to serialize that object into the

not include that field, the JSON sent to the client would not have
that `password`.
* Validation: whatever you return will be serialized with the

corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an

* Validation: whatever you return will be serialized with the

corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an

* Documentation: the generated OpenAPI (and the UI at `/docs`) will
show it as the response (JSON Schema).
* Serialization: you could return an arbitrary object and the
`response_model` would be used to serialize that object into the
corresponding JSON.
* Filtering: the JSON sent to the client will only contain the data
(fields) defined in the `response_model`. If you returned an object
that contains an attribute `password` but the `response_model` does
not include that field, the JSON sent to the client would not have
that `password`.
* Validation: whatever you return will be serialized with the
`response_model`, converting any data as necessary to generate the
corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an
error and return a 500 error code (Internal Server Error).
