About
The TextCaptcha service provides access to textual CAPTCHA challenges via a simple JSON or XML API over HTTP.
The question is the textual challenge that should be presented to the user. The answers are the MD5 hashes of correct lower cased answers: you should be able to check responses from real users you challenge with the question against these checksums.
A text CAPTCHA is more accessible to visually impaired users than their image-based alternatives like ReCAPTCHA. Using text is also more flexible if for example you need to present the challenge over a text-only channel like SMS or IRC.
The problem with text CAPTCHAs is that they provide inherently more information than a distorted image. They are parseable, under the right conditions solveable. With the advent of contextual parsing tools such as Wolfram Alpha, such simple logic puzzles have become easier to solve programatically.

About
VoidCaptcha is a developer-focused CAPTCHA-solving API. It accepts JSON tasks over HTTPS and returns solution tokens, cookies, or text through one endpoint. Supported challenge types include reCAPTCHA v2 and v3, Enterprise and Mobile, Arkose FunCaptcha, DataDome, Imperva Incapsula, Cloudflare Turnstile and Clearance, GeeTest, Hunt Captcha, and AWS WAF. Developers can use the API directly or official Python and Node.js clients. The service supports automated testing, availability monitoring, and data collection. Metered billing is based on successful solves; per-thread subscriptions are available for selected types, and failed solves are not charged. A free test key returns synthetic challenge results for integration checks; live solves are billed from the first solve. The API accepts compatible request formats from 2Captcha, CapSolver, and Anti-Captcha clients, so existing software can switch API hosts.
