Instant Results
Real-time responses optimized for speed — perfect for synchronous AI agent tool calls.
Privacy First
No data stored. All queries are processed securely and privately.
AI Agent Native
Simple JSON REST endpoints designed for LLM tool calling, OpenAI function calling, and autonomous agent pipelines.
Built for AI Agents & LLM Workflows
All endpoints are simple JSON REST APIs — easy to wire up as tools for OpenAI function calling, LangChain agents, Claude tool use, or any autonomous agent framework.
OpenAI / Claude / Gemini
Define any endpoint as a tool function. The agent autonomously decides when to call it and passes structured JSON arguments.
n8n / Zapier / Make
Drop in as an HTTP node in any automation workflow. Enrich leads, validate contacts, and research companies at scale.
LangChain / CrewAI / AutoGen
Wrap any endpoint as a LangChain tool or CrewAI action. Predictable JSON responses make parsing straightforward for agents.
