Highlights

Now you can declare Query, Header, and Cookie parameters with Pydantic models. 🎉

`Query` Parameter Models

Use Pydantic models for Query parameters:

from typing import Annotated, Literal

from fastapi import FastAPI, Query
from pydantic import BaseModel, Field

app = FastAPI()


class FilterParams(BaseModel):
    limit: int = Field(100, gt=0, le=100)
    offset: int = Field(0, ge=0)
    order_by: Literal["created_at", "updated_at"] = "created_at"
    tags: list[str] = []


@app.get("/items/")
async def read_items(filter_query: Annotated[FilterParams, Query()]):
    return filter_query

Read the new docs: Query Parameter Models.

`Header` Parameter Models

Use Pydantic models for Header parameters:

from typing import Annotated

from fastapi import FastAPI, Header
from pydantic import BaseModel

app = FastAPI()


class CommonHeaders(BaseModel):
    host: str
    save_data: bool
    if_modified_since: str | None = None
    traceparent: str | None = None
    x_tag: list[str] = []


@app.get("/items/")
async def read_items(headers: Annotated[CommonHeaders, Header()]):
    return headers

Read the new docs: Header Parameter Models.

`Cookie` Parameter Models

Use Pydantic models for Cookie parameters:

from typing import Annotated

from fastapi import Cookie, FastAPI
from pydantic import BaseModel

app = FastAPI()


class Cookies(BaseModel):
    session_id: str
    fatebook_tracker: str | None = None
    googall_tracker: str | None = None


@app.get("/items/")
async def read_items(cookies: Annotated[Cookies, Cookie()]):
    return cookies

Read the new docs: Cookie Parameter Models.

Forbid Extra Query (Cookie, Header) Parameters

Use Pydantic models to restrict extra values for Query parameters (also applies to Header and Cookie parameters).

To achieve it, use Pydantic's model_config = {"extra": "forbid"}:

from typing import Annotated, Literal

from fastapi import FastAPI, Query
from pydantic import BaseModel, Field

app = FastAPI()


class FilterParams(BaseModel):
    model_config = {"extra": "forbid"}

    limit: int = Field(100, gt=0, le=100)
    offset: int = Field(0, ge=0)
    order_by: Literal["created_at", "updated_at"] = "created_at"
    tags: list[str] = []


@app.get("/items/")
async def read_items(filter_query: Annotated[FilterParams, Query()]):
    return filter_query

This applies to Query, Header, and Cookie parameters, read the new docs:

You can restrict form fields to only include those declared in a Pydantic model and forbid any extra field sent in the request using Pydantic's model_config = {"extra": "forbid"}:

from typing import Annotated

from fastapi import FastAPI, Form
from pydantic import BaseModel

app = FastAPI()


class FormData(BaseModel):
    username: str
    password: str
    model_config = {"extra": "forbid"}


@app.post("/#/")
async def login(data: Annotated[FormData, Form()]):
    return data

Read the new docs: Form Models - Forbid Extra Form Fields.
