Collection of phone numbers from olx.pl

Budget: 4000 UAH Deadline: 7 days

Hello, I have made a similar parser for classifieds: collecting contacts from cards, bypassing phone loading on click, rotating proxies, and delays according to the site's limits. I worked with olx.pl, where phone numbers are provided upon user action; I tested this on live ads. If you are collecting contacts in bulk, it's worth adding a cache of already collected numbers right away, as this removes duplicate requests and reduces the risk of blocks by about 30%. How many ads need to be processed per run, and is this a one-time collection or regular on a schedule? And where do the links to the cards come from, from search by filter or a ready-made list? I suggest we get in touch; I will also outline a solution scheme for collecting phone numbers from olx.pl and show the logic for bypassing protection.

Good day, I have over 5 years of experience in development, data parsing, and JS automation, which I perform regularly.

I will implement a function to obtain phone numbers from olx.pl, taking into account the nuances of the site and creating a stable and adaptable method for changes.

I have attached an example of my work - please take a look.

Approximately 2-3 days for a working version. I will provide the exact cost after a few clarifications or in private messages.

Do you need to automate mass collection or one-time requests, and how do you plan to use the data?

I will develop a secure phone scanner for olx.pl based on a Chrome Extension (Manifest V3 + MutationObserver), using the same architecture that I have already automated for bypassing dynamic DOM and collecting leads in my own CRM system.

How will your current infrastructure bypass Cloudflare Turnstile blocking and generate Bearer tokens for the API request when your "simple JS function" tries to simulate clicking "Show number" more than 50 times in a row?

Good morning. I have a ready-made OLX parser that I constantly maintain in working condition, but as I understand, this is not what you need. I would like to learn more about your vision for the result, after which I can provide guidance regarding the cost.

The phone in OLX opens with a separate scenario, so on the first day, I will show the reproduced request and the function prototype on a test ad. I do not have a confirmed case specifically from olx.pl, and I will not make one up. I will gather a JS function with error handling, test it, and add a short instruction. The complete result will be ready in 2 days.

You need a function in JavaScript that will extract phone numbers from ads on olx.pl. I understand the task: the number is loaded via a separate request after user action, so it can't just be read from the HTML. My plan is as follows. First, I will analyze how the page requests the contact, then replicate this request in code and extract the number from the response, considering the site's limitations and protections. I will format the solution as a separate JS function that can be easily called and integrated into your process. I will test its functionality on real ads. I work with data parsing and JavaScript, so I can take on this task. Reply to discuss the details and let's get started.

Timur, you need to automate the extraction of numbers that are hidden behind a button on the olx.pl advertisement page. This requires bypassing Cloudflare protection and correctly simulating user actions; otherwise, the site blocks requests after a few views. I will develop a script that interacts correctly with the site's API requests and retrieves clean phone numbers without blocks. How do you plan to use this data in the future - in the form of a table or continuous monitoring of new advertisements?

How many phones approximately?
Do you have proxies?

OLX hides the phone number behind a separate request — without simulating a click and tokens, you will get either an empty response or a captcha. I have solved similar tasks on marketplaces: I analyzed network requests, found the necessary endpoint, and bypassed the rate limit. Plan:
1. I analyze the requests when clicking on "Show phone number," find the endpoint and parameters.
2. I write a function in JS (with comments for console insertion) or Python — whichever is more convenient for you.
3. I test on real listings, adding error handling and delays.
4. I provide the code with instructions. I have worked with parsing the Allegro API (OAuth2, rate limit) and a Selenium scraper for collecting data from car auctions. Example: https://freelancehunt.com/showcase/work/selenium-veb-skraper-dlya-izvlecheniya-dannyih/1874474.html What listings need to be processed — a specific URL or search results? How many phone numbers do you plan to collect per day?

I can analyze the available scenario for obtaining numbers and build a function in JavaScript or automation through Apify with subsequent export to Google Sheets or Airtable. Before starting, I will check if the numbers are available through the site's allowed user scenario and what limitations will affect the collection frequency. This will give you a reproducible process rather than a one-time manual collection.

I have not worked with olx.pl before and will not claim otherwise. At the same time, I implemented a lead generator on Apify + OpenAI: potential client data was collected and enriched for further work with the database.

What volume of listings do you plan to process daily or weekly, and for what further work do you need these contacts?
