2Captcha API Documentation

This is the complete API documentation for connecting to the 2Captcha API using MindCloud's Universal API. If you are new to MindCloud, start with the Introduction to see how one API can sit in front of many different apps.

MindCloud is an integration company that offers one normalized API to access 3,100+ apps from a single place. It cleans up provider-specific quirks, keeps requests and responses consistent, and centralizes authentication so you do not need to manage separate flows for every app. Browse other apps.

Meet 2Captcha: 2Captcha solves CAPTCHA challenges through API v2 task creation, polling, balance, and result reporting endpoints. Keep reading to get started.

Quickstart

Before you run your first 2Captcha request, you need three things:

A MindCloud account — sign in or create an account at MindCloud.
A MindCloud API Key — create one in API Keys. Keep it on your server.
At least one 2Captcha connection — create or choose one in Connections. Note its connectionId.

Every 2Captcha action uses the same URL pattern:

POST https://connect.mindcloud.co/v2/universal/apps/captcha/actions/{actionSlug}/run

You need a MindCloud API Key and a 2Captcha connection. Then call an action such as Get Balance:

curl --request POST \
  --url "https://connect.mindcloud.co/v2/universal/apps/captcha/actions/get-balance/run" \
  --header "Authorization: Bearer $MINDCLOUD_API_KEY" \
  --header "Content-Type: application/json" \
  --data '{
  "connectionId": "$CONNECTION_ID",
  "arguments": {}
}'

Every response comes back in the same envelope, with your rows in a data array:

{
  "success": true,
  "data": [
    { "id": "1042", "name": "Ava" }
  ],
  "meta": {}
}

After your first request works, use Shape your requests to control arguments, pagination, filtering, fields, and errors.

Authenticate with a MindCloud API Key plus a connectionId for your 2Captcha account. See 2Captcha API Authentication for the full flow and how to get your connection credentials.
