Support is here: [[https://forum.gsa-online.de/discussion/33131/capv2v3-free-recaptcha-solver/p1|GSA Forum]] - Main coding was done by Forum user [[https://forum.gsa-online.de/profile/CL67F|CL67F]].

===== Overview =====
Capv2v3 is working with these programs:
  * Python (install with Powershell)
  * FFMPEG (install with Powershell)
  * Some Packages (Python) : fastapi, python-multipart, playwright, playwright-recaptcha, uvicorn (install with Python)

===== Content of setup =====
  * **run_caphv2v3.bat** - runs the program _caphv2v3.py (double click on this one after installation and setup!)
  * **caphv2v3.py** - program written in PYTHON (edit this file for changes)

CapV2V3 can work with :

==== Option A: No proxy (optional) ====

The Recaptcha V2 V3 technology detects and register your IP of your PC. If you
use this option, you will get quickly poor success rate.

==== Option B: list of proxies (optional) ====

If file is absent, this functionality is disabled. The proxy is selected in random
order. It is tried 3 times then considered as //failed//, therefore
replaced by an other random proxy in list. The previous proxy is deleted from
the list.

  * **randoming_proxy_data_v2.txt** - list of proxies for recaptcha v2
  * **randoming_proxy_data_v3.txt** - list of proxies for recaptcha v3

Format for the proxy files is always:
<code>182.25.68.36:9985
182.25.68.36:9985:user:password</code>

You can of course also use [[proxy_scraper:options#automatic_export|GSA Proxy Scraper]] and let it export e.g. google passed proxies automatically to this file location.

==== Option C: Rotating proxies (optional) ====

If file is present, this option has priority. If file is absent, this functionality is
disabled. Each access to the address gives a new proxy. Proxies are in rotation.
The proxy is tried 3 times then considered as //failed//, therefore replaced by
an other random proxy from address.

  * **proxy\rotating_proxy_data_v2.txt** - one rotating address for proxies for recaptcha v2
  * **proxy\rotating_proxy_data_v3.txt** - one rotating address for proxies for recaptcha v3

Format for the proxy files is always:
<code>p.webshare.io:9999</code>
==== Logs ====

  * **proxy\failed_proxy_data_v2.txt** - list of failed proxies for recaptcha v2
  * **proxy\failed_proxy_data_v3.txt** - list of failed proxies for recaptcha v3
  * **proxy\worked_proxy_data_v2.txt** - list of worked proxies for recaptcha v2
  * **proxy\worked_proxy_data_v3.txt** - list of worked proxies for recaptcha v3
  * **log\log_v2.txt** - activity of recaptcha v2 solving
  * **log\log_v3.txt** - activity of recaptcha v3 solving

Just leave the HOST as it is (//127.0.0.1:8181// which is the default setup in script).

===== Remarks =====

Capv2v3 works generally with 5 to 10 threads depending on your PC configuration and power.

There are 2 ways how Recaptcha v2 is solved
  * **Audio Solver**
  * **Audio + Image Challenge Solver** - uses first audio and if failed, uses the [[https://dashboard.capsolver.com/passport/register?inviteCode=zwTtNxRntNqE|CapSolver]] for images recognition and therefore needs an API-Key configured.
