Quick start

from acrossed import Acrossed

ac = Acrossed(
    api_key="ack_live_...",
    signing_secret="acsk_...",
)

d = ac.check(ip="203.0.113.1", method="POST", path="/login")
if d.deny:
    print("blocked:", d.reason)

Flask

from flask import Flask, request, abort
from acrossed import Acrossed

ac = Acrossed(api_key="ack_live_...", signing_secret="acsk_...")
app = Flask(__name__)

@app.before_request
def gate():
    d = ac.check_request(request)
    if d.deny:
        abort(403, description=d.reason)

FastAPI (async)

from fastapi import FastAPI, Request, HTTPException
from acrossed import AsyncAcrossed

ac = AsyncAcrossed(api_key="ack_live_...", signing_secret="acsk_...")
app = FastAPI()

@app.middleware("http")
async def gate(req: Request, call_next):
    d = await ac.check_request(req)
    if d.deny:
        raise HTTPException(status_code=403, detail=d.reason)
    return await call_next(req)

Fails open by default. Use fail_closed=True for stricter postures.
