Freeze Shipping Alert and Global Hardiness Zones and Frost Data is a WooCommerce extension that combines the WhatsMy.Zone climate lookup service with live forecast and geocoding services to detect freeze risk for shipping addresses worldwide. Features

Protected Shipping Recommendations - Suggest one or more merchant-defined shipping options when those methods are safer during frost season.
Delivery Scheduling - Customers can schedule later delivery when their area is safe from freezing, with an optional delayed-shipping discount.
Risk Acceptance - Customers can acknowledge and accept freeze risk with a customizable disclaimer.
Worldwide Hardiness Zone Shortcodes - Display hardiness zone, frost dates, and growing season information on any page.
Admin Weather Forecast - Check current weather forecast data for an order's shipping address.
Admin Shipping Controls - Configure shipping lead time, protection products, complimentary protection rules, recommended shipping labels, disclaimers, and delayed-shipping discounts.
Service-Backed Climate Lookups - Zone, frost, growing-season, and shipping-risk lookups are provided through the WhatsMy.Zone service.
Global Coverage - Worldwide climate lookups for supported destinations.
WooCommerce HPOS Compatible - Works with both legacy and High-Performance Order Storage.

Data Sources

Climate Lookups: WhatsMy.Zone service for zone, frost date, growing-season, and shipping-risk lookups
Weather Forecast: Open-Meteo API (free, no API key required)
Geocoding / Address Lookup: Nominatim/OpenStreetMap

WhatsMy.Zone Account and API Usage Freeze Alert connects to WhatsMy.Zone so this site can make authenticated climate lookups and show usage and plan details in the WordPress admin. The initial connection is free and gives the site 100 WhatsMy.Zone API calls per month. If a site needs more calls, the service plan can be upgraded from the plugin settings. WhatsMy.Zone API calls are used when Freeze Alert requests hardiness zone, frost date, growing-season, or shipping-risk data for a coordinate. This includes shortcode lookups, checkout freeze-risk checks, order/admin checks, and configured route exposure points when those features are used. Paid WhatsMy.Zone plans change only the service-side API usage limit; they do not unlock a separate premium version of the WordPress plugin.

Activate the plugin through the 'Plugins' menu
Go to Freeze Alert -> Settings to configure sensitive products, protection options, checkout behavior, and your WhatsMy.Zone service connection

Add shortcodes to your product pages as needed
