Build Your Own Tariff Change Radar in ~70 Lines of Python

说明与用途

使用约70行Python构建关税变更雷达，自动监控公开仓库并在出现新变更时发送Webhook通知。

问题

Tariff changes occur frequently and need timely notification for import pricing decisions.

结果

The radar runs from cron, watches an open dataset, and pings a webhook when the tariff stack moves, avoiding scraping and API keys.

工作流

• Clone or pull the invoicetariff/invoicetariff repo
• Load data/changelog.json and ruleset‑seed.json
• Compare entry IDs against stored state file
• If new entries exist, send a webhook payload
• Update state file with new IDs

证据

Tariff rates don't sneak up on anyone — tariff changes do.

The raw sources are hostile to automation. Federal Register notices are prose; exclusion lists ship as PDF attachments; CBP publishes CSMS messages on a page that assumes a human is reading it.

来源

Three properties make this watchable: Git is the transport; status splits the timeline; the repo ships the ruleset itself.
