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:

• Forbid Extra Query Parameters
• Forbid Extra Headers
• Forbid Extra Cookies
