DeathByCaptcha.js v0.0.1

Node.js client library for the DeathByCaptcha service.

Installation

DeathByCaptcha.js is available in npm.

npm install deathbycaptcha

Usage

Using the API goes a little something like this:

DeathByCaptcha = require("deathbycaptcha");
var dbc = new DeathByCaptcha("your_dbc_user", "your_dbc_pass");

dbc.solve(fs.readFileSync("/your/captcha/file"), function(err, id, solution) {
	if(err) return console.error(err); // onoes!

	if(solution !== "moo") {
		// It was wrong!
		dbc.report(id, function(err) {
			if(err) return console.error(err); // ONOES!
		});
	}
});

Solve CAPTCHA

Send a CAPTCHA image file to DeathByCaptcha to solve.

DeathByCaptcha.solve(captchaImage, callback);

Callback accepts three parameters:

• error: if something went wrong sending or solving the CAPTCHA.
• captchaId: the ID of the CAPTCHA.
• solution: the solution to the CAPTCHA, as text.

Example:

dbc.solve(fs.readFileSync("/your/captcha/file"), function(err, id, solution) {
	if(err) return console.error(err);
	console.log("CAPTCHA solution is", solution);
});

Get CAPTCHA

Gets a previously solved (or in progress) CAPTCHA by ID. If the CAPTCHA is still in progress the callback will wait for it.

DeathByCaptcha.get(captchaId, callback);

Callback takes 3 arguments:

• error: if something went wrong.
• solution: the solution for the CAPTCHA.
• isCorrect: true/false if the CAPTCHA is "correct" (hasn't beenr reported)

Example:

dbc.get(12345, function(err, solution, isCorrect) {
	if(err) return console.error(err);
	// isComplete is false if the CAPTCHA has been reported (see below).
	console.log("Captcha solution is", solution);
	console.log("Is it correct?", isCorrect);
});

Report CAPTCHA

Use this if you have reason to believe DeathByCaptcha incorrectly solved your CAPTCHA image.

DeathByCaptcha.report(captchaId, callback);

Callback will be handed an error if something went wrong, else nothing will be passed.

Example:

dbc.report(12345, function(err) {
	if(err) return console.error(err);
	console.log("CAPTCHA was reported successfully.")
	console.log("If it wasn't older than an hour, it should have refunded");
});

Get Balance

Loads balance stats for your account from DeathByCaptcha.

DeathByCaptcha.balance(callback);

Callback:

• error: if something went wrong
• credits: computed number of CAPTCHA solutions remaining.
• balance: balance in US cents.
• rate: cost per solution in US cents.

Example:

dbc.balance(function(err, credits, balance, rate) {
	if(err) return console.error(err);
	console.log(credits + " credits remaining");
	console.log("($" + (balance / 100) + " @ " + rate + "c/solution");
});
