Brave Search API
Independent web index search API
PaidSearch, vector & RAGbrave.com
What it is
Web search over Brave's own crawled index rather than a resold Google or Bing feed. Returns organic results, news, images and videos as structured JSON, with an Answers endpoint that generates a cited response. Enterprise plans offer full-funnel zero data retention.
Why it earns a slot
An independent index surfaces pages Google-derived APIs cannot, and the licensing is clean for AI grounding. It ships a first-party MCP server so agents can call it directly.
Know before you commit
The $5 monthly credit is roughly 1,000 Search requests and there is no free plan beyond it. Long-tail coverage is shallower than Google's index.
Neighbourhood
How Brave Search API sits against the rest of the atlas — swaps, companions and the tools builders actually save alongside it.
