Overview
SearXNG aggregates results from around 270 search engines without tracking or personalizing, and its JSON output lets a research agent search, dedupe, and brief without per-query fees. One caveat decides it: JSON output is off by default, and most public instances return 403 for it, so using the API means self-hosting and editing config.
