A free web search API on our own 3.1B+ page index
FreeSerp is a free web search API — a keyless way for AI agents to search 3.1B+ web pages in any language and get back ranked, structured JSON with snippets, publication dates and a citation to the crawl record.
curl 'https://freeserp.ai/api.php?index=web&q=how+to+fine-tune+llama+3&lang=en&size=5'No account, no key, no HTML to parse. Pass index=web with a query; add lang=ru or fresh=1 or a published_from date. Each result carries a site card (Domain Rating, category, live date) when we know the domain. Use it as a general web search API for retrieval, grounding, monitoring or agent tool-calls — the Bing Search API was retired in 2025 and Google’s is paid and keyed; this one is free and ours.
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.
