Show HN: XSDR – Real-time event monitoring infrastructure for agents

XSDR is a unified pipeline for monitoring activity on X and the web. I built it because I wanted my agent to do things based on real-time events that were taking place instead of polling the web or scheduling cron jobs.

With XSDR, you can trigger agentic loops based on real-time events. All you need is an API key, a webhook that can receive POST requests, and an idea of what you’re looking for.

It currently supports X and Firehose (aka a persistent web crawler).
