OpenSERP is a free, open-source SERP API and CLI for live search data from Google, Yandex, Baidu, Bing, DuckDuckGo, and Ecosia.
Use it as a search tool for LLMs, agents, and RAG pipelines, or as a scraper backend for SEO rank tracking across Google, Yandex, Baidu, and more. It is especially useful when your workflow needs RU/CN web coverage instead of another Google-only API.
