Key only in the query string, and no security.txt.\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### WeatherAPI.com\n\n1. Pass current_fields, day_fields or hour_fields to cut the response to what you need\n2. Treat a 403 with error code 2007 as the monthly quota, not a bad key. There's no 429\n3. Reuse the id from search.json (q=id:NNN) to avoid ambiguous city names\n4. Cache history freely, current for under an hour and forecasts for under a day, to stay inside the terms\n5. Use https://api.weatherapi.com/v1. The docs still show an http:// base URL\n\n## Other comparisons with Met Office Weather DataHub (Site Specific) or WeatherAPI.com\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 WeatherAPI.com](https://www.anchorterminal.com/compare/accuweather-api-vs-weatherapi-com.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 WeatherAPI.com](https://www.anchorterminal.com/compare/google-weather-api-vs-weatherapi-com.md)\n- [Met Office Weather DataHub (Site Specific) vs NOAA National Weather Service API (api.weather.gov)](https://www.anchorterminal.com/compare/met-office-datahub-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- [NOAA National Weather Service API (api.weather.gov) vs WeatherAPI.com](https://www.anchorterminal.com/compare/nws-api-vs-weatherapi-com.md)\n- [OpenWeather One Call API vs WeatherAPI.com](https://www.anchorterminal.com/compare/openweather-one-call-vs-weatherapi-com.md)\n- [Pirate Weather vs WeatherAPI.com](https://www.anchorterminal.com/compare/pirate-weather-vs-weatherapi-com.md)\n- [Visual Crossing Weather API vs WeatherAPI.com](https://www.anchorterminal.com/compare/visual-crossing-vs-weatherapi-com.md)\n",
