A Go library for solving hCaptchas with any image recognition API.

1v1 me, bro!

Basic Usage

In order to solve, you need the site URL (not the domain!), and the site key, which can be found in the HTML of the website with the hCaptcha challenge.

Below is a basic example of how to use the solver with the two using a simple guessing solver.

c, err := NewChallenge(siteUrl, siteKey)
if err != nil {
    panic(err)
}
err = c.Solve(&GuessSolver{})
if err != nil {
    panic(err)
}
fmt.Println(c.Token()) // P0_eyJ0eXAiOiJKV1QiLC...

Custom Solvers

Custom solvers can be implemented with ease. All solvers need to implement the Solver interface. You can link this with any image recognition API you want.

You can see an example of this with the GuessSolver implementation in solver.go.

Credits

2.0.1

A few changes to support the modern API, and general code cleanup along with a switch to mathgl for Bézier curve creation.

2.0.0

The motion data capturing required with hCaptcha would not be possible without the work of @h0nde and his py-hcaptcha solver in Python.

1.0.2:

There were quite a lot of changes with the hCaptcha API, so the solver was updated to reflect these changes, with the generous help of @aw1875 and his puppeteer-hcaptcha solver in JavaScript.

1.0.0

This project was inspired by the work of @JimmyLaurent and his hcaptcha-solver also in JavaScript. I'd like to thank him for his work, and for being a motivation to create this library.
