Best for
  • SEO and GEO teams needing to understand brand presence in AI search.
  • Developers building AI agents or apps that need access to LLM answers and citation data.
  • Content marketers optimizing for AI visibility.
  • Developers needing quick, API-key-free web search capabilities
  • Privacy-conscious users who prefer local search execution
  • AI application development with Claude Desktop or Claude Code
Not for
  • Scenarios requiring deep analysis of data beyond public pages (e.g., private systems).
  • Users wanting fully local operation and storage (except the free OKF export, it relies on hosted services).
  • Enterprise applications requiring high-scale, reliable search APIs
  • Users needing advanced search features like custom ranking or filters
  • Accessing sites blocked by TLS fingerprinting without installing the optional browser backend
Required permissions
  • Requires an API key for authentication (except for the free local OKF export).
  • Network access to send requests to the Sleepwalker API and receive results.
  • For OKF export, permission to read the target webpage.
  • Outbound network access to DuckDuckGo and other websites
  • Reads environment variables for SafeSearch, region, and CA certificates
  • Optionally reads a CA certificate file (for TLS-intercepting proxies)
Risks and side effects
  • Usage may incur costs; actions like visibility checks, content scoring, and serialization consume credits.
  • Dependency on external APIs and hosted services; potential service outages or data privacy concerns.
  • Content sent to the API might include sensitive information; ensure compliance with privacy policies.
  • Search endpoints may occasionally return empty results or errors, especially when blocked
  • Content fetching may be subject to SSRF protection, blocking private or loopback addresses by default
  • Misuse could lead to rate limiting or IP blocking
