A free alternative to Perplexity
Perplexity is an AI answer engine with a paid API. FreeSerp is a free, keyless web search API for AI agents on our own 3.1B+ page web index — a drop-in alternative you can call with no key, no signup and no per-request bill.
curl 'https://freeserp.ai/api.php?index=web&q=best+crm+for+small+business&size=5'FreeSerp is not a wrapper around Perplexity or anyone else: it runs its own web index, FreeSerp Global — 3.1B+ pages in every language (1.25B+ English, 228M+ Russian, 187M+ German, 162M+ French, 160M+ Japanese…), ranked by text relevance, link authority and domain trust, and returns the capture date and digest behind every result.
Point your agent at FreeSerp’s JSON endpoint with index=web and it searches 3.1B+ pages — url, title, snippet, language, publication date and a site card (Domain Rating, category, live date) per result. The default index gives you 20M+ site profiles with LLM summaries, filterable and sortable on every field. Same shape you would wire Perplexity into, minus the account and the invoice.
