US and territories only.\n\n## Before you call either\n\n### Met Office Weather DataHub (Site Specific)\n\n1. Register an application and subscribe it to the Global Spot plan first. The key is tied to that order and shown once\n2. Send the key in the apikey header with Accept: application/json, and latitude and longitude as query parameters\n3. Add excludeParameterMetadata=true to drop the parameter descriptions from every response\n4. Pick the timestep by need. hourly covers 48 hours, three-hourly 168, daily 7 days, and each call counts against the daily limit\n5. Stop on a 429. The limit is daily and resets at 00:00 UTC\n\n### NOAA National Weather Service API (api.weather.gov)\n\n1. Set User-Agent to your app name and a contact email or the request is refused with 403\n2. Cache the /points response per coordinate. The office and grid rarely change\n3. Round coordinates to four decimal places. More precision returns an error\n4. Don't add cache-busting query parameters. Unknown parameters return 400\n5. Back off about five seconds after a throttled request and reuse the last good response\n\n## Other comparisons with Met Office Weather DataHub (Site Specific) or NOAA National Weather Service API (api.weather.gov)\n\n- [AccuWeather Core Weather API + MCP vs Met Office Weather DataHub (Site Specific)](https://www.anchorterminal.com/compare/accuweather-api-vs-met-office-datahub.md)\n- [AccuWeather Core Weather API + MCP vs NOAA National Weather Service API (api.weather.gov)](https://www.anchorterminal.com/compare/accuweather-api-vs-nws-api.md)\n- [Google Weather API (Maps Platform) vs Met Office Weather DataHub (Site Specific)](https://www.anchorterminal.com/compare/google-weather-api-vs-met-office-datahub.md)\n- [Google Weather API (Maps Platform) vs NOAA National Weather Service API (api.weather.gov)](https://www.anchorterminal.com/compare/google-weather-api-vs-nws-api.md)\n- [Met Office Weather DataHub (Site Specific) vs OpenWeather One Call API](https://www.anchorterminal.com/compare/met-office-datahub-vs-openweather-one-call.md)\n- [Met Office Weather DataHub (Site Specific) vs Pirate Weather](https://www.anchorterminal.com/compare/met-office-datahub-vs-pirate-weather.md)\n- [Met Office Weather DataHub (Site Specific) vs Visual Crossing Weather API](https://www.anchorterminal.com/compare/met-office-datahub-vs-visual-crossing.md)\n- [Met Office Weather DataHub (Site Specific) vs WeatherAPI.com](https://www.anchorterminal.com/compare/met-office-datahub-vs-weatherapi-com.md)\n- [NOAA National Weather Service API (api.weather.gov) vs OpenWeather One Call API](https://www.anchorterminal.com/compare/nws-api-vs-openweather-one-call.md)\n- [NOAA National Weather Service API (api.weather.gov) vs Pirate Weather](https://www.anchorterminal.com/compare/nws-api-vs-pirate-weather.md)\n- [NOAA National Weather Service API (api.weather.gov) vs Visual Crossing Weather API](https://www.anchorterminal.com/compare/nws-api-vs-visual-crossing.md)\n- [NOAA National Weather Service API (api.weather.gov) vs WeatherAPI.com](https://www.anchorterminal.com/compare/nws-api-vs-weatherapi-com.md)\n",
