Scraping and checking bot: database checking, Viber parser and TG parser before promotion. A parser is a tool for collecting data from open sources. In real marketing work, though, the problem is rarely the word itself. The problem is that the list is already bought or exported, the manager is waiting for launch, the client asks when the campaign starts, and nobody has checked what is inside the file.
Some numbers may be dead. Some contacts may not use the messenger you need. A Viber group may have much less useful volume than expected. A TG channel may have three people in comments, even if the subscriber count looks nice.
A bot for checking and parsing does not replace the whole marketing process. It does not write the offer, build the media plan, or create sales from thin air. Its job is practical: accept a file or a link, check whether the task can be processed, calculate the price, show the limits, and send a structured order to a manager.
People search for these tools in very different ways: Viber parser, Telegram parser, parser, parcer, bot checking, bot parcing, bot for TG, WhatsApp checker, VK checker. The label matters less than the workflow: upload a list or send a link, get a price estimate, see the limits, and send to work only what is worth processing.

Parser bot for checking
Checking means working with an existing list. There is a file with phone numbers, emails, or other contacts. The bot accepts the file, sends it for calculation, shows the price, and helps create the order. Boring? Yes. But this boring step often saves money.
Before the ad account, there is often a dirty list: duplicates, old leads, numbers without the required messenger, contacts from different countries, or garbage after manual export. A bot for checking does not magically improve the list. It shows how suitable it is for a specific channel.
TXT or CSV format
The bot expects TXT or CSV. One number per line. Digits only. No spaces, dashes, plus signs, commas, dots, comments. Automated checking breaks easily when one row contains a phone number, name, city and a manager’s note.
Rows and unique contacts
The bot shows how many rows were in the file and how many unique contacts remain. Sometimes the number hurts: 30,000 rows turn into 18,400 unique contacts. In a presentation the base was big. In work, not so much.
Why checking comes first
Checking the list after launch is like checking the landing page after the traffic has burned. Possible, but not smart. Checking helps decide whether TG, Viber, WhatsApp, MAX or email makes sense for this list.
Bot for TG checking
TG deserves a separate section. For promotion, it is not only about numbers. Username, activity, and technical account signals can matter. A chatbot for Telegram in this workflow should not just accept a file; it should help choose the depth of checking.
TG short
TG short checks whether a TG account is found by phone number. Simple answer: yes or no. Enough for the first cut.
TG detailed
TG detailed may include phone, TG ID, TG nickname, Premium, last online time and offline days. This can already be used for segmentation and quality assessment.
TG full
TG full may include first name, last name, gender, age and photo link if these fields are available. Full data makes sense only when someone will actually use it.
Viber checker
Viber is still alive in many local and mass-market tasks. Before communication in Viber, it is better to understand how much of the base is actually found.
Viber short
Viber short shows whether a number exists in Viber. Nothing fancy. For a first estimate, this is often enough.
Viber full
Viber full may include phone, name, last online time, age and photo. These fields are useful if they affect segmentation, manual review or prioritisation.
MAX checking
MAX checking helps verify whether contacts exist in MAX. If the channel is new for the business, do not build the launch on the feeling that people are probably there.
MAX short
MAX short answers the basic question: is the contact found. A hypothesis that dies during checking is cheaper than one that dies after budget.
MAX full
MAX full makes sense when the channel is already chosen and additional data is needed.
WhatsApp checker
WhatsApp is often used for requests, consultations and repeat touches. A WhatsApp bot or WhatsApp chatbot in this workflow starts not with a pretty greeting, but with a basic question: is there a contact we can work with?
WhatsApp short
WhatsApp short shows number availability. It is a useful first filter before any communication where WhatsApp is considered a working channel.
WhatsApp full
WhatsApp full may include number, online date and time, age, gender and photo link. Not every team needs this.
VK, Signal, social media and Email
The checking section is not limited to the main messengers. The bot can work with VK, Signal, Facebook, Instagram, TikTok and Email.
VK and Signal
VK and Signal are narrower scenarios. A VK bot makes sense when there is a real plan for those contacts, not just because someone wants one more channel.
Social profiles
Social checks can help with audience evaluation and manual qualification. But a social profile is not the same as product interest.
Email checking
Email checking helps verify address validity. In email marketing, a dirty base hurts not only one campaign but also domain reputation.
Parser and audience collection
Scraping is not checking. Checking works with an existing list. Scraping collects an audience from a source: Viber groups, TG groups, channel comments.
People often search for a free parser when they want to just export the audience. Sometimes it can help with a small one-off task. But in real promotion, questions appear quickly: what was collected, where are duplicates, which countries are included, are there filters, what happens when the source fails.
Scraping as source validation
A group link is not yet a marketing audience. First you need to understand what can be collected, how much it costs and whether it is worth processing.
Why Scraping does not guarantee sales
A collected contact is not a buyer. The result still depends on the offer, channel, frequency, base quality and whether the first message burns the audience.
Viber parser
The Viber parser workflow is built around an invite link to a group or community. The user can send one link or several links at once. A bot extracts invite.viber.com even from messy pasted text.
Messy Viber links
The bot can find the link inside a message. Text before the link should not break the flow.
Several Viber groups
If several Viber links are sent in one message, the bot processes them one by one and shows one combined report.
Viber Scraping settings
Viber Scraping can include phone country filters: Ukraine, russia, Belarus, Kazakhstan, Uzbekistan, United Kingdom, Poland, Moldova. It can also filter member types: superadmins, admins, regular members.
Viber group report
The report shows each group as a separate block: link, estimated quantity, price, order ID and total cost.
Selecting groups for work
After calculation, the bot asks which groups should be sent to work. Calculation is not an order yet.
Telegram parser
TG Scraping is split into groups and channels. A bot for TG chat works with one logic, a bot for TG channel with another. Mixing them up produces bad expectations very quickly.
Bot for TG chat and group
A Telegram parser for a TG group must warn early: if phone numbers are needed, they are hidden for many users. If usernames are needed, they may be available only for part of the members. Admin bot for telegram.
TG channel parser
TG channel Scraping is limited to comments under posts. If there are no comments, there is almost nothing to parse.
Checking the link
If the user selects group Scraping but sends a public channel, the bot can detect it and warn them. For private invite links, a manager may need to review it manually.
Checking and Scraping cost
Checking usually returns the cost faster. Scraping can take longer. The bot creates an order, waits for calculation, polls the status and notifies the user when the data is ready.
Why calculation takes time
Scraping is not just opening a link. The source has to be processed, data has to be collected, and the price has to be calculated.
Minimum price
Small volumes may have a fixed minimum price. If a group is too small, a 15 USD minimum can apply.
Order ID
Every calculation has an ID. “That group” is a bad identifier. ID is better.
FAQ about checking and Scraping bots

What is the difference between a checking bot and a Scraping bot?
A checking bot verifies an existing list. A Scraping bot collects an audience from a source: groups, communities, comments.
Why parser, parcer, bot checking and bot parcing?
Because people search this way. Some use English, some make typos, some mix languages. Inside the product, the workflow matters more than the label.
