The search API that gives AI agents real-time web context
Low-latency search endpoints (Lite, Auto, Deep) return ranked pages, highlights and structured fields from an independent index covering a large share of the public web.
Retrieve full page text or token-efficient highlights with configurable crawl policies, so models get only the most relevant excerpts rather than whole documents.
Run asynchronous agent runs that navigate, reason and return structured outputs with grounded citations across 70M+ companies and other verticals.
Schedule recurring queries over news, people, companies and financials, and receive updates through webhooks when something changes.
The managed vector database and knowledge engine for production AI
Store and query vector embeddings with automatic indexing that requires no manual tuning or algorithm selection.
Writes are acknowledged in under 100ms and become searchable within seconds, while all data is searched in parallel so speed holds at scale.
Connect agents to Pinecone through plugins for Claude Code, Cursor, Copilot, Codex, Gemini CLI, MCP, or a direct REST API with one key.
Serve compiled, governed enterprise knowledge to agents through a single query, cutting token usage and latency versus multi-step RAG loops.
