2Captcha is a service that provides automated CAPTCHA solving solutions, enabling developers to bypass various types of CAPTCHAs in their applications. On Nagent, Twocaptcha is exposed as a fully-configurable developer tools integration that any agent can call — 5 actions, and API key authentication. No code is required to wire Twocaptcha into your workflow — connect it once via the External Integrations panel and reuse it across every agent you build.
Agent builders use Twocaptcha to automate the kinds of tasks developer tools teams previously handled manually. Concrete examples — each one is a single agent step in Nagent — include:
Every action and trigger is paired with a structured input/output schema (visible in the sections below), so when you wire Twocaptcha into Helix — our agentic agent builder — the editor knows exactly what each step expects and produces. Configure once, deploy anywhere across your Nagent agents.
Every operation an agent can call against Twocaptcha, with input parameters and output schema. Drop these into any step of an agent built in Helix.
TWOCAPTCHA_CREATE_TASKCreates a new CAPTCHA-solving task and returns a taskId for retrieving results. Supports multiple captcha types: reCAPTCHA v2/v3, hCaptcha, image recognition, and more. After creating a task, use the returned taskId with getTaskResult to retrieve the solution. Requires sufficient account balance to process tasks.
Input parameters
Task object with 'type' field and type-specific parameters. Common types: 'ImageToTextTask' (requires 'body' as base64 image), 'RecaptchaV2TaskProxyless' (requires 'websiteURL' and 'websiteKey'), 'RecaptchaV3TaskProxyless' (requires 'websiteURL', 'websiteKey', 'minScore', 'pageAction'), 'HCaptchaTaskProxyless' (requires 'websiteURL' and 'websiteKey'). Example: {'type':'RecaptchaV2TaskProxyless','websiteURL':'https://example.com','websiteKey':'6Le-abc...'}
Your software ID from 2Captcha's Software Catalog.
Your 2Captcha API key (32-character hexadecimal string).
Your registered pingback URL to receive results.
Worker language preference: 'en' for English (default), 'rn' for Russian.
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
TWOCAPTCHA_GET_BALANCETool to retrieve your 2Captcha account balance in USD. Use when you need to check available funds before creating captcha-solving tasks.
Input parameters
Your 2Captcha API key (32-character hexadecimal string).
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
TWOCAPTCHA_REPORT_INCORRECTReport that a CAPTCHA solution was declined by the target website. Use this action to provide feedback when a solved CAPTCHA is rejected, enabling 2Captcha to improve accuracy and potentially issue refunds for incorrectly solved tasks.
Input parameters
The ID of the task that was incorrectly solved. This is the taskId returned from createTask.
Your 2Captcha API key (32-character hexadecimal string).
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
TWOCAPTCHA_REPORT_INCORRECT_IMAGE_CAPTCHAReport that an image captcha solution was incorrect. Alias for reportIncorrect method. Use this when you receive an incorrect captcha solution from 2Captcha to report the issue. Made for compatibility with certain software libraries. Successful reports may result in refunds.
Input parameters
The ID of the task to report as incorrect. Must be a valid task ID from a previous captcha solution.
Your 2Captcha API key (32-character hexadecimal string).
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
TWOCAPTCHA_TEST_REQUESTDebug method to verify how the API parses request parameters. Use when troubleshooting integration issues or validating parameter formats.
Input parameters
Your 2Captcha API key for authentication. This is the only required parameter.
Output
Data from the action execution
Error if any occurred during the execution of the action
Whether or not the action execution was successful or not
No publicly available marketplace agent is found using this tool yet. There are 94 agents privately built on Nagent that already use Twocaptcha.
Build on Nagent
Connect Twocaptcha to any Nagent agent in minutes — no API key management, no boilerplate. Just configure and deploy.
The five questions agent builders ask before adopting a new integration.
Open the External Integrations panel inside Nagent (app.nagent.ai/externalIntegration), find Twocaptcha, and click "Connect Now." You'll authenticate with an API key — Nagent handles credential storage and refresh automatically. Once connected, Twocaptcha is available to any agent in your workspace.
No. Nagent provides no-code integration for every tool. Once Twocaptcha is connected, you configure its 5 actions directly in the agent builder UI — no API calls, no boilerplate, no schema management.
Helix — Nagent's agentic agent builder — lets you drop Twocaptcha steps into any workflow visually. Pick an action (e.g., one of those listed above), fill in the inputs (Helix knows the required vs. optional schema for each parameter), and connect it to upstream/downstream steps. Triggers run as the entry point of an agent, so when a Twocaptcha event fires, the agent kicks off automatically.
Every Twocaptcha action and trigger ships with a fully-typed schema — input parameters with name, type, required flag, and description, plus the output payload shape. The schemas are documented in the sections above. Helix uses these schemas to validate your configuration at build time and to type-check the data flowing between steps.
Yes. While Twocaptcha ships with 5 pre-built developer tools actions, you can layer custom logic around them inside Helix — pre/post-processing steps, conditional branches, retries, or stitching Twocaptcha together with other connected tools.
