Getting Started

This API requires an API key for authentication. Here's how to get started:

Sign up — Visit the API's website and create a free account.
Get your key — After signing up, you'll receive a unique API key (usually found in your dashboard or account settings).
Include it in requests — Add your API key to each request, typically as a query parameter (?api_key=YOUR_KEY) or in the request header (Authorization: Bearer YOUR_KEY). Check the API's documentation for the exact format.

API keys are free for most public APIs. They're used to identify your application and enforce rate limits — not to charge you.

Frequently Asked Questions

What weather data does HG Weather provide?

HG Weather is a weather API that can provide meteorological data such as temperature, humidity, wind speed, precipitation, and forecasts. The exact data fields depend on the API's endpoints — check the documentation for a full list of available weather parameters. Many weather APIs also provide UV index, air quality, and severe weather alerts.

Can I get historical weather data from HG Weather?

Historical weather data availability varies by API. Some weather APIs like HG Weather offer historical records going back years, while others focus only on current conditions and forecasts. Check the API documentation to see if historical endpoints are available and whether they require a different plan or rate limit.

How accurate are the forecasts from HG Weather?

Weather API accuracy depends on the data sources the provider uses (e.g., government stations, satellites, radar). Short-term forecasts (1-3 days) are generally reliable across most weather APIs, while extended forecasts become less accurate. HG Weather may source data from national weather services or proprietary models — see their documentation for details on data sources and update frequency.

Does HG Weather support location-based weather lookups?

Most weather APIs support lookups by geographic coordinates (latitude/longitude), city name, or zip code. HG Weather likely supports at least one of these methods. Coordinate-based lookups tend to be the most precise. Check the Weather category for other weather APIs if you need a specific lookup method.

Is HG Weather free to use?

Yes, HG Weather is listed as a free public API. You will need to create a free account to get an API key, but the key itself is free. Some APIs have rate limits on their free tier, so check the official documentation for current limits.
