Searchpin

Self-hosted web search for AI agents — zero API keys, zero cost. pip install searchpin and you're done.

• Search quality rivals commercial products — four search engines in parallel (Baidu, Sogou, Bing CN, Bing Intl), merged and re-ranked by semantic similarity. A rare capability among free MCP search tools.
• Zero-cost agent development — no API keys, no sign-ups, no usage limits. Pair with a local LLM and your entire development loop costs nothing. Run 24/7 agent experiments without worrying about quotas.
• Pollution detection — automatically flags results that are unrelated to your query, so your agent doesn't chase irrelevant content.
• Cross-verification — results from four independent sources let your LLM corroborate information across engines, raising the credibility of what it finds.
• Content extraction that handles modern sites — goes beyond basic HTML-to-text to extract SSR hydration payloads (Next.js, Nuxt), JSON-LD structured data, and microdata from pages that would otherwise return empty.
• Token-conscious output — results are titles, URLs, and snippets only. Your LLM decides which pages are worth fetching in full. Structured extraction data is compact and truncated, keeping token overhead under control.
