📡 API Poller

$4.99

A Python API monitoring tool that polls any HTTP endpoint on a configurable schedule, detects response changes using hash comparison, fires alerts when values shift or endpoints go down, and logs all results to a local SQLite database. Wire it to status pages, pricing APIs, or any data source you want to watch — without standing up full monitoring infrastructure.

What’s Included

  • Poller core (~180 lines) with configurable endpoint list and intervals
  • Hash-based change detection — only alerts on actual data changes
  • JSONPath extractor for monitoring specific fields in API responses
  • Downtime detection with configurable failure threshold before alert
  • Alert channels: SMTP email and Slack webhook (no SDK required)
  • SQLite result log — query response history, latency, and change events
  • README with endpoint config guide and alert setup examples
  • MIT License — use in commercial projects
