Request

Parse Request using await request.json():

from fastapi import FastAPI, Request
from some_supabase_client import client  # example placeholder

app = FastAPI()

@app.post("/signup")
async def sign_up(request: Request):
    body = await request.json()
    email = body.get("email")
    password = body.get("password")

    result = client.auth.sign_up({
        "email": email,
        "password": password,
    })

    return result.data

Pydantic

Pydantic automatically parses json request object:

from fastapi import FastAPI
from pydantic import BaseModel

app = FastAPI()

class SignUpRequest(BaseModel):
    email: str
    password: str

@app.post("/signup")
def sign_up(payload: SignUpRequest):
    result = client.auth.sign_up({
        "email": payload.email,
        "password": payload.password,
    })
    return result.data
