Registration is available via GitHub 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.

4. Service Tiers

free = search + preview (rate limited)

pro = full writeups + flags + API key + MCP access + higher limits

Paid subscriptions are billed through Stripe. You may cancel at any time. Refunds are handled on a case-by-case basis within 7 days of purchase.

5. Acceptable Use

You agree not to:

  • Scrape, crawl, or bulk-download content beyond normal usage

  • Share API keys or account credentials with third parties
  • Attempt to exploit, hack, or disrupt the service infrastructure

  • 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.

6. Content and Intellectual Property

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

7. API and MCP Usage

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.
