A free search API for AI agents
FreeSerp is a free search API for AI agents — a keyless alternative to the paid SERP and search APIs, over our own 3.1B+ page web index and a 20M+ site-profile index.
curl 'https://freeserp.ai/api.php?q=fintech&sort=dr&order=desc&size=5'One JSON call returns ranked results; use index=web for any page on the web or the default site index for profiles with LLM summaries, filterable and sortable on any field. Or connect the MCP server and let an agent call it natively. No key, no signup, no per-request billing.
Two indexes, one endpoint. index=web searches FreeSerp Global, our own 3.1B+ page web index — any URL, any language, ranked by text relevance, link authority and domain trust, with a site card (Domain Rating, category, live date) on every hit. The default FreeSerp Main index (main pages only) holds 20M+ live sites at homepage level with LLM summaries, Domain Rating and AI-niche taxonomy, filterable and sortable on every field.
