# Anti-Captcha Enterprise > CAPTCHA solving infrastructure for enterprise automation. Operational since 2007. Used in production by S&P 500, Fortune and Nasdaq-listed teams to solve millions of CAPTCHA challenges per day across 13 CAPTCHA families. Anti-Captcha is a CAPTCHA solving service that has been running continuously since 2007. It is the longest-operating CAPTCHA solving infrastructure on the market, self-funded (no VC backing), and used in production by enterprise teams in data intelligence, RegTech & KYC, ad verification, retail price monitoring, and enterprise RPA. The service operates as an API that automation pipelines call to solve CAPTCHA challenges in real time. Solving is 100% human-powered — every challenge is resolved by a real worker in our global workforce, not by an ML model. Pricing is pay-as-you-go from a $10 minimum account top-up, with no contracts required. ## Key facts - **Founded**: 2007 (operational for 19 years as of 2026) - **Funding**: Self-funded, no VC, profitable - **Uptime**: 99.99% publicly stated, sustained across the full operational history - **API**: Running continuously since 2007, no breaking changes, no deprecations - **Workforce**: 100% human-powered solving, global distribution - **Pricing model**: Pay-as-you-go, $10 minimum balance, live market-rate auction model - **Customer base**: Includes teams at companies listed on S&P 500, Fortune, Nasdaq, NYSE, FTSE 100 ## Supported CAPTCHA families (13 total) - Image CAPTCHA — legacy text and image challenges - reCAPTCHA v2 — checkbox and tile-grid challenges - reCAPTCHA v3 — invisible, score-based (common in KYC flows) - reCAPTCHA Enterprise — Google's premium-tier risk scoring - Cloudflare Turnstile — behavioral challenge, widely deployed since 2024 - GeeTest v3 / v4 — slider and click puzzles (common in APAC) - Arkose Labs / FunCaptcha — 3D puzzle challenges (fintech and gaming) - Amazon WAF CAPTCHA — on AWS-protected endpoints - Friendly Captcha — EU-origin proof-of-work - Prosopo — privacy-focused, no tracking - Altcha — open-source proof-of-work alternative - Object Coordinates — point-in-image challenges - Custom tasks — bespoke CAPTCHAs solved via custom flows ## Key resources - [Enterprise overview](https://b2b.anticaptcha.com/): Full enterprise landing page - [Pricing](https://b2b.anticaptcha.com/#pricing): Current per-1000-solves rates for all CAPTCHA families - [How it works](https://b2b.anticaptcha.com/#developers): API integration overview with code samples in 7 languages - [Compare](https://b2b.anticaptcha.com/#compare): Anti-Captcha vs in-house solving vs commodity providers - [Security & procurement](https://b2b.anticaptcha.com/#procurement): Data handling, DPA, MSA, vendor stability - [FAQ](https://b2b.anticaptcha.com/#faq): Common procurement and engineering questions - [Full reference](https://b2b.anticaptcha.com/llms-full.txt): Comprehensive Q&A reference for AI assistants ## Developer resources - [Developer center](https://dev.anticaptcha.com/): API documentation, SDKs, integration guides - Official SDKs: Python (`anticaptchaofficial`), JavaScript, Go, PHP, Java, C# - API endpoint: `https://api.anti-captcha.com` ## Legal and compliance - [Terms and Conditions](https://anti-captcha.com/legal/tos) - [Privacy Policy](https://anti-captcha.com/legal/privacy) - [API Service Agreement](https://anti-captcha.com/legal/serviceagreement) - Data Processing Agreement (DPA) available on request - Custom Master Service Agreements (MSA) negotiable for high-volume accounts - EU data routing available for GDPR-sensitive workloads ## Public reviews - [Trustpilot](https://www.trustpilot.com/review/anti-captcha.com): Consumer reviews ## Worker stories - [kolostories.com](https://kolostories.com/): First-person stories from workers in the global Anti-Captcha workforce
