⬇️ Install

npm i capsolver-npm

✋ Usage

1. Import module.

    const CapSolver = require('capsolver-npm')

2. Define tasks handler (singleton).

    const handler = new CapSolver(apikey) // captcha task handler

❗ 2 version for handle captcha tasks results are the followind:

1️⃣ task-binded methods (handle results in one step)

example: check capsolver.com balance + run for one hcaptcha token (.hcaptchaproxyless()):

const CapSolver = require('capsolver-npm')
const handler = new CapSolver('CAI-XXXX ...', 1) // verbose level 1
let b = await handler.balance()
if (b > 0) {  // usd balance
    await handler.hcaptchaproxyless('https://websiteurl.com/', '000000-000000000-0000000')
        .then(async response => {
            if (response.error === 0) {
                console.log(response.solution)
            } else {
                console.log(`[myapp][task error: ${response.apiResponse.errorCode}]`)
            }
        })
}

2️⃣ build taskData schema for a task type and run any task.

Check task parameters at official docs in order to bind manually captcha tasks.

example: run for one hcaptcha token w/ custom proxy (.runAnyTask()):

const CapSolver = require('capsolver-npm')
const handler = new CapSolver('CAI-XXXX ...')

await handler.runAnyTask({
    type: 'HCaptchaTask',
    websiteURL: 'https://website.com/',
    websiteKey: '000000-00000-000000-000000000',
    proxyInfo: {
        // string format also supported
        // 'proxy': 'proxy.provider.io:23331:user1:password1',
        'proxyType': 'http',
        'proxyAddress': 'ip_address',
        'proxyPort': 3221,
        'proxyLogin': 'username',       // not required
        'proxyPassword': 'password'     // not required
    },
})
    .then(async response => {
        if (response.error === 0) {
            console.log(response.solution)
        } else {
            console.log(`[myapp][task error: ${response.apiResponse.errorCode}]`)
        }
    })

↩️ Get solutions

All methods returns the following schema:

Parameter	Type	Description
error	number	[-1] Request/Solving error. [0] Success solve.
statusText	string	HTTP status string.
apiResponse	object	Results/solution (capsolver.com API response).
solution	object	Solution got from success solve.

// ✅ success response
{
    error: 0,
    statusText: '200 OK',
    apiResponse: {
        errorId: 0,
        taskId: '4e6c33f5-bc14-44d0-979e-d5f37b072c59',
        status: 'ready',
        solution: {
            gRecaptchaResponse: '03AIIukzgCys9brSNnrVbwXE9mTesvkxQ-ocK ...'
        }
    }
}

// ❌ Error response (invalid API key example)
{
    error: -1,
    statusText: '400 Bad Request',
    apiResponse: {
        errorId: 1
        errorCode: 'ERROR_INVALID_TASK_DATA',
        errorDescription: 'clientKey error',
    }
}

📖 Supported captcha tasks

Method	Returns
await handler.balance()	get balance as float number
await handler.runAnyTask(taskData)	not use a specific task method

For custom proxy usage in tasks build this schema:

// version 1
// (proxyLogin & proxyPassword are optionals)
const proxyInfo = {

    'proxyPort': 3221,
    'proxyLogin': 'username',
    'proxyPassword': 'password'
}

// version 2
const proxyInfo = {
    proxy: 'proxyType:proxyAddress:proxyPort:proxyLogin:proxyPassword'
}
