Slot Availability Alert Automation

@amitpandeyposin

Hi! I'll build a lightweight Python monitor: curl_cffi with browser TLS/JA3 impersonation, state-change detection (no duplicate alerts), and instant Telegram messages for both 'available' and 'gone'. For IPs, a low-cost approach: a self-hosted Ubuntu VPS proxy pool with rotation, set up via Ansible/README. Includes config file, mocked-state test script, and setup docs. Which site/region and check interval do you need?

@mahmoudembaby1

Hi, that’s a service I have extensive experience in. I built tens of alert systems with Python that send alerts to Telegram when conditions are met. I am very excited to help you get this task done as soon as possible for only $100, with minimum cost of execution. I am ready to get started immediately and will be happy to talk to you soon to get more details about the service you are planning to build.

Handling WAF fingerprinting requires matching the full TLS signature and HTTP/2 framing using curl_cffi alongside a clean, stateful session loop. ✅ Python monitoring service built with curl_cffi Chrome/Safari TLS impersonation, automatic header order alignment, and backoff handling. ✅ Lightweight proxy rotation layer with health checking and complete Ubuntu VPS deployment scripts (configured as an auto-restarting systemd service). ✅ State-diff alert engine wiring into the Telegram Bot API to notify exclusively on status toggles without duplicate spam. ✅ Mock test harness to validate state changes and push notifications safely before targeting the live endpoint. ✅ 10+ years production experience | 400+ completed projects | 320+ five-star reviews ✅ Microsoft® Certified: MCSA | MCSE | MCT & cPanel Certified (CWSA-2) Does the target slot endpoint return a clean internal JSON payload or server-rendered HTML, and does querying it require maintaining an authenticated session cookie? I can deliver this in 1 day for 135 USD and can jump on it right now.

The requirement for stealth requests due to the strict WAF is critical for the success of this project. Implementing curl_cffi along with TLS-impersonation will help mimic genuine browser behavior and evade detection. I’ll evaluate both methods to determine which provides the most stable performance. The first step involves developing the core scraper using the selected techniques, followed by integrating a reliable IP rotation method such as a self-hosted VPS proxy setup. Before starting, I’d like to confirm your preferred method for monitoring the state changes and any specific Telegram chat settings you have in mind. With a 98% completion rate over 126 projects, I understand the nuances of automation in web scraping. What specific Telegram chat configuration do you envision for receiving alerts?

@PINESCRIPTERR

Hi, I can build the Python monitoring service with a resilient HTTP layer using curl_cffi where appropriate, configurable proxy routing, state-change detection, and Telegram alerts that trigger only when availability actually changes. I’ll keep the service lightweight and fault-tolerant with retries, timeouts, logging, duplicate protection, and clear configuration, plus Ubuntu deployment instructions and a mocked test flow for validating the alerts. Question 1: Does the target site require authentication/session cookies in addition to its WAF protection, and will you provide the required access/session setup? Question 2: Are you authorized to monitor this page and use the proposed proxy/IP-routing approach, and are there any specific request-rate or availability constraints we should respect? Regards, Houssame.

**Available now to build your slot alert with stealth checks and instant Telegram pushes** I am Anand and this is right in my lane with curl_cffi and TLS impersonation to beat strict WAF fingerprinting. For stealth I will use curl_cffi impersonating Chrome with session persistence and fallback header ordering to keep traffic looking like a real browser. For zero to low cost rotation I will wire a self hosted Ubuntu VPS proxy chain with dynamic IP switching plus open source aggregator fallback so no costly residential subs needed. For Telegram I will push only on real state flips available to unavailable and back with deduped state tracking so zero spam. You get clean Python source with config for URL interval token and chat ID plus Bash Ansible steps for VPS setup plus a mocked test script proving alerts fire. Recent work: built stealth slot monitor with curl_cffi and VPS rotation for booking site, built Telegram change detector with sub second push for inventory flips. Can I see the target slot page and your Ubuntu VPS specs so I can start today

@Hrolgar

Most WAF stacks like Cloudflare and Akamai fingerprint the TLS handshake itself, the JA3 hash, not just headers or user agent, so a plain requests session gets flagged before a cookie is even set. That's why curl_cffi's impersonation profiles, chrome120 or safari17_1, matter here rather than just rotating user agents. For the proxy side I'd run a small pool of residential or datacenter IPs behind a rotating layer, worked into the poll loop so a block on one exit node just rotates instead of killing the run. State comparison sits on top, diffing the relevant fields so Telegram only fires when available/unavailable actually flips, not on every poll. I'd start by mocking the state change locally, swap the response, confirm the alert fires once and stays quiet on repeats, which gets a working demo before touching the real WAF. Once that's proven I move to the live target and tune the impersonation profile and rotation cadence against it. Rough split for the 600: M1: mocked demo, polling loop, Telegram alert on simulated flip, $200, 1d. M2: curl_cffi/TLS impersonation on the live page plus proxy rotation, $250, 2d. M3: dedupe hardening, error handling, handover, $150, 1d. The 600 is my read off the brief. The real unknown is how aggressive the WAF gets once I hit it live, so I'll firm the number up once I see the target. Send me the URL and I'll have a tighter number back tomorrow.

Hi, I can build the monitoring service with a clean Python polling loop, persistent state tracking and Telegram alerts so you only get notified when availability actually changes. I’m comfortable with curl_cffi/browser-like HTTP clients, proxy routing and handling protected pages, and I’ll keep the service lightweight with clear configuration and proper error/retry handling. I’ll also include the Ubuntu setup instructions and a small mocked test so you can verify the available/unavailable alerts without touching the real site.

@Sv3nie

IF YOU ARE NOT HAPPY YOU DON'T PAY! The risk here isn't curl_cffi, it's the state machine: if a WAF challenge page parses as "no slots", you get a false "slots available" alert the moment it clears. I'd make blocked/unknown its own state and only push to Telegram on a confirmed parse flip. For the IP side I'd keep the proxy layer behind one interface so it stays swappable. Honestly, free self-hosted rotation means datacenter ranges, which a strict WAF blocks harder than residential, so jitter and session reuse matter more than raw IP count. Is the slot page behind a login, or reachable without a session? Send me a message and I'll explain exactly how I'd approach your project.

Hello there, I can build a resilient Python monitoring service with curl_cffi, browser-like TLS behavior, state-change detection, and instant Telegram alerts with clean configuration and logging. I can also provide the Ubuntu VPS/proxy setup, deployment instructions, and a mocked test script to verify availability/unavailability alerts without notification spam. I’ll keep the implementation lightweight, reliable, and easy to maintain, with clear source code and deployment documentation.

@arslanshahid386

Hi, I see you're looking to develop a Python service that monitors a protected "slot" page and sends alerts via Telegram when availability changes. The project involves navigating a strict WAF and requires stealthy HTTP requests using curl_cffi or TLS-im to avoid detection. The main technical challenge here is bypassing the site's WAF without triggering security mechanisms, which could block requests. My approach would involve assessing the site's fingerprinting techniques, ensuring the requests mimic genuine browser traffic. Prioritizing the stability of the scraping mechanism is crucial to maintain consistent monitoring without interruptions. I have experience in web scraping and developing alert systems, particularly using Python, PHP, and Linux environments. My past projects include similar work where I successfully bypassed security layers to gather data in real-time. Q1 – What is the specific URL of the slot page, and are there any known changes in its structure over time? Q2 – Do you have specific requirements for the frequency of checks, or should it be as frequent as possible without being blocked? Q3 – Is there a preferred format or additional data that should be included in the Telegram alerts? Looking forward to hearing from you.

@Aaleen110

The main risk is the WAF fingerprinting and blocking your requests. I handle this by using curl_cffi and TLS-impersonation to mimic real browser traffic. I will build a Python service using those libraries to check the page repeatedly. When it detects the change from "no slots" to "slots available," it will send a Telegram notification. Does the target site require specific headers beyond what's standard for impersonation? I need confirmation of the Telegram bot token and chat ID before starting. I have a 5.0 rating across 10 reviews here, also Preferred Freelancer status.

@TeraByte26

Hi Gurdeep, I will deliver a Python service that checks the slot page every few seconds, uses curl_cffi/TLS‑impersonation with a VPS‑based rotating proxy, and sends a single Telegram alert on each availability change. I can have it running on your Ubuntu VPS within 48 hours. Shall I start with a mock‑test script? Best, Alex Waiting for your response in chat! Best Regards.

Hey, This one's right up my alley - I've built this kind of stealth monitor-and-alert setup before (FedEx account automation past Akamai Bot Manager, proxy integration, DrissionPage CDP), so none of these pieces are new to me. Plan: - curl_cffi for TLS/JA3 impersonation on the request layer, with a session-refresh fallback if the WAF starts flagging fingerprints - Self-hosted proxy chain on a cheap Ubuntu VPS (or a couple) with rotating outbound IPs - skips residential proxy subscriptions entirely, and I'll hand over setup scripts/README so you can add nodes yourself later - A simple last-status vs current-status diff so Telegram only fires on real transitions, no spam - Clean config block - target URL, interval, bot token, chat ID all in one place I can have a working version, VPS setup steps, and a mock-alert test script ready in 3-4 days. Quick questions before I start: do you already have a VPS for the proxy piece, or should provisioning be in scope? And do you know which WAF this is (Cloudflare, Akamai, PerimeterX, custom), or is that part of what needs figuring out? Happy to share relevant past scraping/automation work if useful.

@deshasoft

hello , i have created some applications like that , please check my last projects done on my profile thanks.

@codeandcommand

I have built scrapers exactly like this. For a protected slot page, I would run a Python service with requests or Playwright depending on the auth type, poll every few seconds with jitter to stay under the radar, and push alerts through a queue so nothing gets missed on a fast VPS deploy. Can start today, working version within 48 hours. The 30 to 250 range is a starting point based on the post, real numbers depend on how the page is protected, which we can nail down in a quick call.

@albertc1996

Hi, I can build a lightweight Python service that monitors slot availability and sends alerts whenever the status changes, with duplicate notifications prevented through state tracking. The solution will include configurable check intervals, robust error handling, logging, and bot integration. I’ll also provide a simple Ubuntu VPS setup guide and a mock test to demonstrate both availability and unavailability alerts. I can implement reliable HTTP monitoring with "curl_cffi" where permitted, while respecting the target site's access controls and rate limits. You’ll receive clean, documented source code, configuration instructions, and a ready-to-run solution.
