Captcha solvers

Using your own proxies with DeathByCaptcha

DeathByCaptcha is one of the older captcha solving services, with an HTTP API and client libraries for the common languages.

Why DeathByCaptcha needs a proxy

Many sites tie a captcha token to the IP address that asked for it. If the service solves from its own address and you submit from yours, the token can be refused. Passing your proxy to the service makes both come from one address.

Which proxy to use

A residential proxy with a sticky session.

What to enter

A PiratProxies plan gives you four things: a host, a port, a username and a password. These are the values for Residential; the username and password are on your plan page.

Hostresi.piratproxies.com
HTTP port8080
SOCKS5 port1080
UsernameUSERNAME
Passwordfrom your plan page

As one address:

http://USERNAME:PASSWORD@resi.piratproxies.com:8080

The country and the session are chosen in the username, not in a separate setting. The generator on your plan page writes the username for you, and Targeting and sessions explains each part.

Steps

  1. For token captchas, the parameters are sent as a small JSON object.
  2. Add proxy with the full address, http://USERNAME:PASSWORD@resi.piratproxies.com:8080, and proxytype set to HTTP.
  3. Submit the token from your own client through the same proxy.

Rotating or sticky

Use a sticky session, and give DeathByCaptcha exactly the same username you use for your own requests. The session ID in the username is what keeps both on one IP address. With a rotating username the token is solved from one address and submitted from another, and sites that check this reject it.

A sticky username looks like this:

USERNAME-country-us-time-600-session-a1b2c3d4

If it does not work

  • The proxy is written as one address with the username and password in it, not as separate fields.
  • A 407 error means the username or password was not accepted. Copy both again from your plan page, and check that nothing added a space or cut the username short.
  • If the IP address is in the wrong country, look at the username: the country code is part of it. More fixes.
