Web Slot Monitoring Tool

I need a reliable, fast VFS appointment booking bot for high-demand visa centers (slots disappear within 1 minute of opening).Core Requirements:Fast slot detection via HTTP polling (sub-second checks, multi-center support, proxy rotation to avoid blocks).
Instant slot hold/select — when a slot is detected, the bot must send the hold/select request within 1–3 seconds (critical part, because slots are taken instantly by others).
Full flow: login → OTP handling → slot polling → hold on detection → pre-fill form → Turnstile CAPTCHA solve → payment request (UPI QR generation for manual approval).
Telegram alerts on slot found / hold success / payment page ready.
Long-term support: regular updates when VFS changes endpoints, CAPTCHA, or anti-bot measures.

Important Notes:Pure HTTP polling for detection is fine (fast & lightweight).
Slot hold / form submit / payment step usually requires handling Cloudflare Turnstile CAPTCHA and browser-like behavior — hybrid approach is acceptable:HTTP for fast polling
Headless browser (Playwright / Puppeteer with stealth) only when slot is found (for CAPTCHA + hold + submit)
Extract cookies/session after hold and return to HTTP

Realistic target: 5–7 seconds end-to-end from slot detection to payment page (best case 5–10 seconds).
