FEATURES

Everything you need for real-time capture

From fetch interception to WebSocket dispatch — every component optimized for zero detection and minimal latency.

🌐

Chrome Extension MV3

Strict PAGE/ISOLATED/SW architecture. Monkey-patch fetch + XHR for transparent capture.

  • Multi-host (es/de/it/fr/uk/com)
  • Auto-pagination up to 20 pages
  • CSRF auto-capture from real traffic
🐍

Python Receiver (FastAPI)

WebSocket + HTTP server for capture, dispatch and storage. Local SQLite for audit.

  • Deduplicated pool with TTL grace period
  • Parallel multi-dispatcher broadcast
  • Auto-stop on consecutive fails
📊

Live Dashboard

6 live charts + tabs for recent captures and raw JSONs from RAM with ZIP download.

  • Status pie · latency · body size
  • Polls/min sparkline
  • Fetch ms · recv→UI ms
🛡️

10-Gate Safety Chain

Book defense in depth: file gate + popup toggle + DOM verify + URL verify + LEVEL 4 fetch/XHR block.

  • book_unlock.json gate file
  • Lock tour ID + URL match
  • Native Amazon error code
🎯

Pull via UI Click

Click on the native Refresh button. Full telemetry, indistinguishable from a real user.

  • Robust selector via SVG path
  • Trusted click events
  • Zero bot signature
⚡

Real-time WebSocket

Instant push to dispatchers (UI, agent, etc). Queue with reconnect + backoff on connection loss.

  • 200 messages queue in background
  • Concurrent broadcast (asyncio.gather)
  • __server_ts for latency tracking
🔍

UI with advanced filters

Tours page with custom filters: country, city, distance, payout, ppd, duration, equipment, time windows, multi-stop.

  • Savable presets (see FILTER_PRESETS)
  • Instant client-side filtering
  • Highlight + sound on match
📦

Raw JSON Export

Ring buffer with last 1000 raw JSONs in RAM. ZIP download with _manifest for audit/replay/training data.

  • Ring configurable via env var
  • Download 50/100/500/1000 as ZIP
  • Formatted JSON preview in UI
🔔

Alerts & Notifications

Automatic move-to-top on new tours, CSS highlight, configurable sounds (new/price/booked), auto-clear timer.

  • 3 distinct sounds (new/price/booked)
  • Visual move-to-top + animation
  • Per-panel alert config

FLOW

From fetch to dispatcher in <50ms

1

Fetch Amazon

Amazon page JS makes the request normally /api/loadboard/search

2

Ext intercept

injected.js monkey-patch captures response + measures fetch_ms

3

IPC Bridge

postMessage → content_script → background SW

4

WS push

background.js sends payload through WebSocket to receiver

5

Broadcast

Receiver diff vs POOL → parallel broadcast to dispatchers

STEALTH

What Amazon sees — honest analysis

Detection profile identical to a real user using the Amazon Relay UI.

⚠️ What Amazon SEES

  • Normal HTTP requests Standard server-side logging. Unavoidable — user makes the request via UI anyway.
  • Normal headers (cookie, csrf, UA) Pass-through, unchanged by extension.
  • Trusted click events Pendo, csa.ContentInteraction see native clicks. Good for us: shows real user activity.
  • window.fetch wrapped Theoretically via fetch.toString(). Production anti-bot does not check this in practice.

✅ What Amazon DOES NOT SEE

  • Internal postMessage __relay_capture: true — they have no listener with this filter.
  • performance.now() local Just CPU clock, zero network.
  • Captured body Stays on device + private LAN WebSocket.
  • btn.click() vs trusted Native event listeners fire identically. Empirically verified on real Amazon production.
  • WebSocket to receiver Private LAN, inaccessible from amazon.com origin.
