Greyline by The Meridian Lab is a managed reverse proxy that detects autonomous AI agents (LangChain, AutoGPT, CrewAI, OpenClaw, crawlers, etc...) probing your API using 24 signals, then interrogates, delays, or poisons them before they reach real infrastructure. One CNAME, zero code changes. tl;dr: Deploy your own counter agent to hunt and kill unwelcome agents on your web properties
