Open-source Java framework for building AI agents and LLM apps
Configure any supported provider with an API key and model name, then call chat() for a consistent interface across models.
AgentRunner combines policy and middleware to coordinate models, tools and sandboxes inside a single execution flow.
Reusable, versionable capability definitions that bundle a SKILL.md, scripts and assets, discovered from local directories or remote storage.
Add knowledge retrieval, image generation and OCR pipelines on demand, mixing synchronous and asynchronous execution styles.

Web search API and crawler built for AI agents
Run natural-language or keyword queries against a large independent web index with filters for domain, date and category.
Return cleaned page text and AI-extracted highlights so agents receive the most relevant excerpts instead of entire pages.
Choose fast, balanced or deep search modes so an assistant can answer instantly or run longer grounded research.
Extract structured outputs such as company details, people and other entities for list building and data pipelines.
