Neural search API. Find pages by meaning, not keywords.

Semantic search engine that indexes the open web with embeddings — pass a description, get matching pages. Strong for research-style queries and find-similar workflows; formerly known as Metaphor.

Production-grade web search API for AI agents.

A web search API built for LLMs and agents. Linkup returns sourced, cited answers with full-text snippets in seconds, plus a Fetch endpoint for URL extraction and a Research endpoint that runs multi-step, chain-of-thought deep research. It integrates via MCP and SDK wrappers for OpenAI, LangChain, CrewAI, and more, and offers zero-data-retention enterprise hosting.

Independent search index. Privacy-respecting, non-Google.

API access to Brave's independently-crawled search index. Useful when you need a non-Google source, want to dodge upstream rate limits, or have privacy posture requirements that rule out scraping competitors.

Search-foundation APIs — Reader, embeddings, and reranker — for grounding LLMs.

A suite of search-foundation APIs for retrieval and RAG: a Reader that turns any URL or web search into LLM-ready markdown, multilingual multimodal embeddings, and a reranker. One key spans every service, the Reader is open source, and the embedding models are also released as open weights for self-hosting.
