How to Solve CAPTCHA with CapSolver (API Method)

Below is a generic example for solving reCAPTCHA v2/v3 using CapSolver’s API.

Step 1: Create a Task

curl -X POST https://api.capsolver.com/createTask \
-H "Content-Type: application/json" \
-d '{
    "clientKey": "YOUR_API_KEY",
    "task": {
        "type": "ReCaptchaV2TaskProxyLess",
        "websiteURL": "https://example.com",
        "websiteKey": "SITE_KEY_HERE"
    }
}'

Response:

{
  "errorId": 0,
  "taskId": "c58f78b1-1234-4fb5-bec8-abc123"
}

Step 2: Get the Solution

curl -X POST https://api.capsolver.com/getTaskResult \
-H "Content-Type: application/json" \
-d '{
    "clientKey": "YOUR_API_KEY",
    "taskId": "c58f78b1-1234-4fb5-bec8-abc123"
}'

Solved response:

{
  "errorId": 0,
  "status": "ready",
  "solution": {
    "gRecaptchaResponse": "03AHJ...token..."
  }
}

Use the generated gRecaptchaResponse token to bypass the CAPTCHA.

Solving CAPTCHA with CapSolver in Real Automation

Python + Playwright Example

import requests
import playwright.sync_api

API_KEY = "YOUR_API_KEY"

def solve():
    task = {
        "clientKey": API_KEY,
        "task": {
            "type": "ReCaptchaV2TaskProxyLess",
            "websiteURL": "https://example.com",
            "websiteKey": "SITE_KEY"
        }
    }
    task_id = requests.post("https://api.capsolver.com/createTask", json=task).json()["taskId"]

    while True:
        res = requests.post("https://api.capsolver.com/getTaskResult", json={
            "clientKey": API_KEY,
            "taskId": task_id
        }).json()

        if res["status"] == "ready":
            return res["solution"]["gRecaptchaResponse"]

token = solve()
print("Solved CAPTCHA:", token)

Node.js + Puppeteer Example

const axios = require("axios");

async function solve() {
  const create = await axios.post(
    "https://api.capsolver.com/createTask",
    {
      clientKey: process.env.CAPSOLVER_KEY,
      task: {
        type: "ReCaptchaV2TaskProxyLess",
        websiteURL: "https://example.com",
        websiteKey: "SITE_KEY"
      }
    }
  );

  const taskId = create.data.taskId;

  let result;
  while (true) {
    const resp = await axios.post(
      "https://api.capsolver.com/getTaskResult",
      { clientKey: process.env.CAPSOLVER_KEY, taskId }
    );
    if (resp.data.status === "ready") {
      result = resp.data.solution.gRecaptchaResponse;
      break;
    }
  }

  console.log("CAPTCHA Solved:", result);
}

Solving AWS WAF CAPTCHA with CapSolver

CapSolver supports AWS WAF, one of the most advanced CAPTCHA systems in 2025.

Example task:

{
  "clientKey": "YOUR_API_KEY",
  "task": {
    "type": "AntiAwsWafTaskProxyLess",
    "websiteURL": "https://your-site.com",
    "awsKey": "...",
    "awsIv": "...",
    "awsContext": "..."
  }
}

CapSolver returns an aws-waf-token you can use in cookies to pass the challenge, making it usable even in highly secure environments.
