scraped.langchain-ai__langgraph

Graph-based framework for building stateful, multi-actor LLM applications on top of LangChain. Models agent execution as a graph of event handlers where each step emits and receives typed events, enabling nested and parallel agent pipelines. Embeds into Python scripts, notebooks, and REST APIs via Starlette/FastAPI.

Health Monitoring: This tool has not yet been probed by the automated outreach worker. Probes evaluate HTTP endpoint reachability with bounded timeouts.

Recorded Probe Scope: Reliability status is derived solely from automated endpoint reachability probes (HTTP status & network connectivity). It confirms server liveness at the recorded timestamp and does not certify semantic correctness, execution safety, or formal security audit.
