# 2Captcha Skill

Solve CAPTCHAs programmatically using the 2Captcha human-powered service.

## Installation

```bash
# One-line install
curl -fsSL https://raw.githubusercontent.com/adinvadim/2captcha-cli/main/solve-captcha \
  -o /usr/local/bin/solve-captcha && chmod +x /usr/local/bin/solve-captcha

# Verify
solve-captcha --version
```

## Configuration

```bash
# Save your 2Captcha API key
mkdir -p ~/.config/2captcha
echo "YOUR_API_KEY" > ~/.config/2captcha/api-key

# Or use environment variable
export TWOCAPTCHA_API_KEY="your-key"
```

Get your API key at https://2captcha.com/enterpage

## Quick Reference

### Check Balance First
```bash
./solve-captcha balance
```

### Image CAPTCHA
```bash
# From file
./solve-captcha image /path/to/captcha.png

# From URL  
./solve-captcha image "https://site.com/captcha.jpg"

# With options
./solve-captcha image captcha.png --numeric 1 --math
./solve-captcha image captcha.png --comment "Enter red letters only"
```

### reCAPTCHA v2
```bash
./solve-captcha recaptcha2 --sitekey "6Le-wvk..." --url "https://example.com"
```

### reCAPTCHA v3

It works — treat it as a last resort, not the default

A thin CLI over the 2Captcha human-solving service: install one script, drop the key in ~/.config/2captcha/api-key or TWOCAPTCHA_API_KEY, check `solve-captcha balance`, then solve. It is reliable when you genuinely must clear a challenge during automation. Two caveats: you are paying per solve, and the solving is done by humans, so it belongs after respectful rate limiting rather than as your first answer to a 403.

Use case: Form automation that occasionally hits a single interstitial CAPTCHA

Sending captchas to a human solver from the shell

Check the balance before a batch so a run does not die halfway through with an empty account.

Solvers are human and paid, so latency varies and a tight timeout on each call will discard valid answers.

Image challenges accept hints such as numeric only or math mode, which lifts the solve rate noticeably.

The key sits in a plain file in the config directory, so treat that path as a secret.

Prefer the environment variable form in containers so no key file needs to persist on disk.

This skill wraps the 2captcha service in a small command line client, so a browser automation flow can hand a puzzle off to human solvers instead of stalling. It covers image challenges and the two main recaptcha variants. ## What it does - Solves image based challenges taken from a local file or a remote image reference. - Handles recaptcha version two using a site key and a page address. - Handles recaptcha version three with a site key, an address and an action name. - Accepts hints such as numeric only mode or math mode for image challenges. - Reports the remaining account balance before work starts. ## When it is the wrong choice Every solve is a paid, human answered request with unavoidable latency, so this is the wrong tool for high volume collection where per unit cost dominates and a slower free approach could work at all. It also means a third party sees the challenge, which is unacceptable for pages behind a contractual or privacy boundary. For plain rate limits and cookie walls, better session handling is both cheaper and faster. ```bash # check funds before starting a batch solve-captcha balance # image challenge taken from a local file, hints are passed as options solve-captcha image captcha.png # recaptcha variant two needs a site key and a page address # recaptcha variant three adds an action name on top of those ``` ## Working notes - The key lives either in a config file under the user config directory or in an environment variable. - Hints raise the solve rate enough to be worth always supplying when known.
