Terms of Service

By accessing or using CTF Base (ctfbase.com), including the API and MCP Server, you agree to be bound by these Terms of Service. If you do not agree, do not use the service.

CTF Base is a knowledge base of Capture The Flag (CTF) competition writeups. The service provides:

• Web interface for searching and reading CTF writeups
• REST API for programmatic access
• MCP Server for AI assistant integration

Registration is available via GitHub, Discord, or Google OAuth. By creating an account, you confirm that you are at least 13 years of age. You are responsible for maintaining the security of your account credentials and API keys.

We reserve the right to suspend or terminate accounts that violate these terms or engage in abusive behavior.

CTF Base intentionally does not distribute final challenge flags. Each full writeup provides the methodology and technical detail needed to reproduce the solution in the original challenge environment.

Paid access is sold as a one-time purchase for 30 or 365 days. Card and available wallet payments are processed by LAVALANE LTD through LAVA.top; cryptocurrency payments are processed by NOWPayments. Access starts after the selected provider confirms payment and expires at the end of the paid period. These purchases do not renew automatically and create no recurring charge.

Refund eligibility, request instructions, and the effect of an approved refund on access are described in our Refund Policy. Payment-method availability may vary by country, currency, device, and provider.

You agree not to:

• Scrape, crawl, or bulk-download content beyond normal usage
• Redistribute writeup content as your own or in a competing service
• Share API keys or account credentials with third parties
• Attempt to exploit, hack, or disrupt the service infrastructure
• Use automated tools to bypass rate limits or access controls
• Use the service for any unlawful purpose

We monitor for anomalous access patterns and reserve the right to rate-limit or block abusive usage without notice.

CTF writeups are based on publicly available CTF competitions. The analysis, solutions, and educational commentary are original work. All content is provided for educational purposes.

You may reference and link to writeups. You may not reproduce substantial portions of content without attribution.

API and MCP access is subject to rate limits based on your service tier. Exceeding limits will result in 429 Too Many Requests responses. Persistent abuse may result in key revocation or account suspension.

API keys are confidential. If you suspect a key has been compromised, revoke it immediately from your dashboard.

To the maximum extent permitted by law, CTF Base shall not be liable for any indirect, incidental, or consequential damages arising from your use of the service. Our total liability shall not exceed the amount you paid for the service in the 12 months preceding the claim.

We may update these terms from time to time. Material changes will be communicated via email or a notice on the website. Continued use of the service after changes constitutes acceptance.
