Bing Search API alternative — the TutuSoo API

An independent search API — own index + web fallback, one request.

Many teams are seeking a long-term, reliable alternative as the Bing Web Search API changes. TutuSoo is an independently operated search API built on its own index, not tied to a single vendor’s product roadmap.

It returns structured JSON with source attribution, supports llms.txt, and tokenizes Chinese with jieba — a stable way to wire retrieval into AI apps and agents.
