Show HN: XSDR – Real-time event monitoring infrastructure for agents
XSDR provides a unified pipeline for monitoring activity on X (Twitter) and the web via a persistent crawler. It enables triggering agentic loops based on real-time events, using an API key and a webhook endpoint, instead of relying on polling or scheduled cron jobs.
Background
- "Show HN" is a Hacker News tradition where makers share side projects for community feedback. Hacker News is a tech-news site (run by Y Combinator) heavily followed by engineers, founders, and investors.
- XSDR is middleware for "agents" — AI systems that autonomously act (post, buy, scrape) instead of just generating text. The pitch: instead of having an agent repeatedly check for updates (polling) or run on a timer (cron jobs), XSDR pushes real-time events to a webhook.
- It ingests two data sources: X (formerly Twitter) and a "Firehose" — a continuous web crawler that streams page changes.
- The broader context: the AI agent ecosystem is booming, but reliable real-time event infrastructure for agents is still fragmented. XSDR competes with RSS-to-webhook services, Twitter API wrappers, and custom scrapers, combining both X monitoring and general web crawling in a single API.
