Integracija s Pythonom

Python je mogoče popolnoma zaščititi — brez paketa in brez odvisnosti. Preverjanje je en sam klic HTTPS.

Ne objavljamo SDK za Python. To govori o naši distribuciji, ne o vaši zaščiti: kar počnejo SDK-ji, spodnji klic opravi s standardno knjižnico.

1. Vstavitev pripomočka

Skript meri vedenje v brskalniku in v vsak obrazec vstavi skrito polje. Vstavite ga enkrat v glavo strani.

HTMLhtml

<!-- Add to <head> with SRI for security -->
(function () {
  var KEY = "YOUR_API_KEY";
  var SITE = location.hostname;
  var V = "2025.09.1";
  var s = document.createElement('script');
  s.src = "https://api.silentshield.io/client.js?k=" + encodeURIComponent(KEY)
    + "&v=" + encodeURIComponent(V)
    + "&site=" + encodeURIComponent(SITE);
  s.async = true;
  s.crossOrigin = "anonymous";
  document.head.appendChild(s);
})();

2. Preverjanje na strežniku

Ob pošiljanju preberite skrito polje in nas vprašajte, preden sprejmete oddajo. Brez tega koraka odloča samo brskalnik — bot brez JavaScripta pa gre mimo.

Flask, Django in FastAPI

Zgornja funkcija ni odvisna od ogrodja. Tri mesta klica so v komentarju na koncu odseka: Flask bere slovar obrazca, Django podatke POST, FastAPI parameter obrazca.

Ko nismo dosegljivi

Odsek obiskovalca spusti naprej. Neupravičeno zavrnjena stranka stane več kot spuščen bot. Če želite obratno, v veji z napako vrnite neresnično — takrat vas motnja stane oddaje.

Agenti UI

Opažanja agentov sporočajte po istem vzorcu na telemetrično končno točko: en POST in ista glava.
