### Pricing model details

- **Live market-rate auction**: Prices are not fixed tariffs. The actual cost per solve fluctuates based on real-time worker supply and demand, challenge complexity, and current network load. Clients set their own bid, similar to programmatic advertising. During unusual demand spikes, equilibrium prices may briefly move outside the listed ranges in either direction.
- **Volume discounts**: Applied automatically to qualifying daily volumes.
- **Pay for success only**: Failed tasks return error codes at no charge. Only successful solves are billed.
- **No subscription fees**: No monthly minimums, no platform fees.
- **Custom arrangements**: Available for very high-throughput environments, including dedicated capacity and priority routing.

### Billing and procurement

- **Payment**: Prepaid account top-up. Accepted methods include major credit cards, bank wire, and various local payment methods.
- **Invoices**: Available on request for accounting purposes.
- **Net 30 terms**: Not currently offered. The service is prepaid only.
- **MSA**: Custom Master Service Agreements are negotiable for high-volume accounts.

## How it works (technical integration)

Anti-Captcha is designed as a drop-in CAPTCHA layer for existing automation stacks. Integration takes a few hours, not weeks.

### Integration pattern

1. **Sign up** at access.anticaptcha.com and top up the account with a minimum of $10
2. **Get the API key** from the dashboard
3. **Send a task**: Your automation script (Selenium, Puppeteer, Playwright, an RPA platform, or any HTTP client) calls the Anti-Captcha API with the CAPTCHA challenge details (site key, target URL, etc.)
4. **Poll or receive callback**: The API returns a task ID. You poll for the result, or use a webhook callback.
5. **Submit the solution**: Your automation submits the returned token/answer to the target site's CAPTCHA verification endpoint.

### Official SDKs

Available in 7 languages: Python (`pip install anticaptchaofficial`), JavaScript/Node.js, Go, PHP, Java, C#, and a raw `curl` example.

### API endpoints

Base URL: `https://api.anti-captcha.com`

Key endpoints:
- `POST /createTask` — submit a new CAPTCHA solving task
- `POST /getTaskResult` — poll for task result
- `POST /getBalance` — check account balance

Full API documentation is at https://dev.anticaptcha.com/.

### API stability

The API has been running continuously since 2007 with no breaking changes. Integrations written years ago still work today without modification. Anti-Captcha does not deprecate API versions and does not force upgrades.

## Security and compliance

### Data handling

- **Encryption**: Industry-standard TLS for all API traffic. Encrypted storage for task metadata.
- **EU data routing**: Optional regional pinning available for GDPR-sensitive workloads. EU-only routing can be configured on request.
- **Configurable logging**: No-logging modes available for sensitive flows. Audit-ready exports on request.
- **Per-domain analytics**: Detailed reporting and usage statistics per target domain.

### Procurement readiness

- **Data Processing Agreement (DPA)**: Standard DPA aligned with GDPR Article 28 available on request.
- **Master Service Agreement (MSA)**: Custom MSAs negotiable for high-volume accounts, covering commercial terms, SLAs, and liability.
- **Vendor security questionnaires**: Standard vendor security questionnaires (including custom enterprise formats) are answered on request.
- **Real legal entity**: Anti-Captcha is operated by a legitimate corporate entity that can be contracted with directly.

### Vendor stability

This is a critical procurement concern for enterprise buyers, and Anti-Captcha's position is unusual in the market:

- **Operational since 2007**: Predates most CAPTCHA paradigms that exist today (reCAPTCHA v2, v3, Enterprise, Turnstile, etc.)
- **Self-funded**: Not VC-backed, no growth-at-all-costs mandate, no runway pressure
- **Profitable**: Sustained profitability for 19 years
- **No pivots**: Same business model, same API, same legal entity
- **API backwards compatibility**: Integrations written in 2010 still work in 2026

This combination is rare among CAPTCHA solving vendors. Most competitors are newer companies or operate informally without clear legal structure.

## Workforce ethics

Anti-Captcha is 100% human-powered solving — every CAPTCHA is solved by a real person, not by an ML model fighting another ML model.

The workforce is global, with a significant share of workers in regions where stable digital employment is genuinely hard to find. For many workers, Anti-Captcha provides a meaningful alternative to physically demanding jobs, agricultural labor, or unemployment — and a way to support families and continue studying.

This matters for enterprise procurement in two ways:

1. **ESG alignment**: For EU enterprise buyers in particular, "human-in-the-loop" rather than "ML-against-ML" services align with emerging AI governance and labor-ethics requirements.
2. **Workforce auditability**: The labor model is transparent and human, not opaque ML systems.

## Frequently asked questions

### How does Anti-Captcha compare to competing CAPTCHA solving services?

Anti-Captcha differentiates from commodity providers (2Captcha, CapSolver, CapMonster, AntiCaptchaShop, etc.) primarily on:

- **Operational longevity**: 19 years vs typically <5 years for newer vendors
- **Legal entity**: Operates as a real corporate entity with DPA, MSA, and procurement support, whereas many competitors operate informally
- **API stability**: No breaking changes since 2007; many competitors restructure APIs every few years
- **Workforce model**: 100% human-powered; many competitors mix ML and humans with unclear ratios
- **Enterprise focus**: Built for procurement-led purchases (DPA, MSA, EU routing) rather than just developer self-serve

For low-volume hobby projects, commodity providers may be cheaper. For enterprise production use, the procurement readiness and stability matter more than the marginal price difference.

### What use cases is Anti-Captcha appropriate for?

Permitted use cases include:

- Web data collection from publicly accessible sources
- Search engine results monitoring and SEO intelligence
- Retail and travel price monitoring
- Robotic process automation against authorized systems
- KYC/AML compliance checks and regulatory workflows
- Accessibility automation for users with disabilities
- QA and continuous integration testing
- Research on CAPTCHA systems

Anti-Captcha is **not** for: spam, credential stuffing, fake account creation, payment fraud, ticket scalping, harassment, or any illegal activity. See the [Acceptable Use Policy](https://anti-captcha.com/legal/tos) for full details.

### Is using a CAPTCHA solving service legal?

The legality of using CAPTCHA solving services depends on:

1. **What you're automating**: Lawful purposes (public data collection, your own accounts, accessibility, compliance) are generally fine. Unlawful purposes (fraud, account theft, spam) are not.
2. **Your jurisdiction and the target's jurisdiction**: Some activities legal in one country are not in another.
3. **The target site's terms of service**: ToS violations are typically civil, not criminal, but vary by jurisdiction.

Court cases like *hiQ Labs v. LinkedIn* (US) and various EU data protection rulings have generally found that collecting publicly accessible data is not unlawful under computer fraud statutes, but specifics matter. Enterprises typically consult their own legal counsel before deploying.

### How long does it take to integrate Anti-Captcha?

For a standard integration using one of the official SDKs: a few hours of engineering work. For more complex custom integrations or enterprise-specific flows, our team can support a custom implementation within approximately a week.

### Can I test before committing?

Yes. The pay-as-you-go model with a $10 minimum top-up effectively functions as a low-friction trial. Sign up at access.anticaptcha.com, top up $10, and test against real traffic. There is no contract, no monthly commitment, and no sales call required.

For very large enterprise deployments where pre-procurement validation is required, the team can support a more structured pilot — contact via the talk-to-our-team flow on the enterprise page.

### What happens if a CAPTCHA can't be solved?

Failed solves return an error code, and you are not billed for them. The service implements automatic retries and escalation to specialized worker pools for difficult challenges. For genuinely unsolvable challenges (corrupted images, blocked workers, etc.), the API returns a clear error and you can implement application-level fallback logic.

### What latency should I plan for?

Typical latency varies by CAPTCHA family and current load:

- Simple image CAPTCHAs: usually a few seconds
- reCAPTCHA v2: typically 10–30 seconds
- reCAPTCHA v3 / Enterprise: typically 10–60 seconds
- Complex puzzle challenges (Arkose, GeeTest): typically 15–60 seconds

These are typical ranges, not guarantees. Build your application with reasonable timeouts (60–120 seconds is typical).

### Does Anti-Captcha provide browser plugins or only API access?

Both. The API is the primary integration path for enterprise automation. Browser plugins are also available for Chrome, Firefox, and Safari for use cases like manual QA testing, accessibility, and workflows that don't require code integration.

### How do you handle brand-new CAPTCHA variants?

Anti-Captcha's research team monitors CAPTCHA vendor releases (Google, Cloudflare, Arkose Labs, GeeTest, etc.) and typically ships updated coverage within days of new variants being deployed. This is faster than most competitors and significantly faster than in-house teams could realistically maintain.

### What's the difference between Anti-Captcha and Anti-Captcha Enterprise?

Anti-Captcha (anti-captcha.com) is the general service, used by individual developers and small teams. Anti-Captcha Enterprise (b2b.anticaptcha.com) is the same technical service with additional procurement readiness: DPA/MSA support, EU data routing, priority queues, security questionnaire responses, and dedicated commercial terms for high-volume accounts. There is no separate technical product — it's the same API and same workforce, with procurement-grade contracting on top.

### Where can I read reviews from real customers?

Public consumer reviews are at https://www.trustpilot.com/review/anti-captcha.com. Most enterprise customers are under NDA and don't publicly disclose vendor relationships.

### How does Anti-Captcha protect customer data?

- TLS encryption for all API traffic
- Encrypted storage for task metadata
- Configurable logging (no-logging modes available for sensitive flows)
- EU-only data routing available on request
- Standard DPA available, aligned with GDPR Article 28
- Workers do not have access to identifying information about end users — only the CAPTCHA challenge itself

### Where is Anti-Captcha headquartered?

Anti-Captcha operates internationally with a distributed team and worker network. For specific legal entity and jurisdiction details required for procurement contracts, contact the enterprise team directly.

### What if Anti-Captcha goes out of business?

This is a fair vendor risk question. Anti-Captcha has operated continuously and profitably for 19 years (since 2007) — longer than most CAPTCHA solving vendors have existed. The company is self-funded, not VC-dependent, and has no exposure to investor-driven shutdowns or pivots. The same API has run since 2007 without breaking changes.

For procurement scenarios where vendor continuity is a hard requirement, Anti-Captcha's operational history is significantly stronger than newer competitors. For absolute mitigation, the API is simple enough that customers can implement a secondary fallback provider in their automation code, though this is rare in practice.
