Terms forbid using the data to train, validate or otherwise inform any AI system.\n\n**meteoblue Weather API.** Eight of the APIs publish OpenAPI 3.1 specs, and the Forecast API spec lists the credit cost of every package. A public Pingdom page shows monthly uptime per API. The key travels only in the query string, the free trial covers nine forecast packages, and no security.txt, certification or DPA was found.\n\n## Before you call either\n\n### AccuWeather Core Weather API + MCP\n\n1. Cache location keys. They don't change, and the lookup is the call worth saving\n2. Use the geoposition search first when you hold coordinates, then the forecast tools with the key it returns\n3. Send the key as a Bearer header, not in the MCP URL, so it stays out of logs\n4. Send Accept-Encoding: gzip and refresh on the Expires header rather than a fixed timer\n5. Show the AccuWeather name and logo next to the data, and keep nothing older than two weeks\n\n### meteoblue Weather API\n\n1. Pass `lat`, `lon` and `apikey` to `https://my.meteoblue.com/packages/\u003cpackage\u003e`. Join packages with commas, such as `basic-1h,basic-day`, to get several in one call\n2. Budget credits before calling. One call costs 4,000 to 96,000 credits by package, and the free trial holds 10 million for a year. Read `MB-Credits-Accounted` on each response\n3. Set `forecastDays` and pick the coarsest resolution that does the job. Without it the API returns every forecast day it has\n4. Call with a 30-second timeout, wait 30 seconds after an error and stop after 10 retries, as the availability page advises. The default limit is 500 calls a minute\n5. Keep the key out of logs, since it is part of every URL. Ask for a shared secret and send `expire` and `sig` if URLs may be seen by others\n\n## Questions\n\n### Which is better for AI agents, AccuWeather Core Weather API + MCP or meteoblue Weather API?\n\nmeteoblue Weather API scores 61.7 (C) on agent readiness against AccuWeather Core Weather API + MCP's 48.4 (D), and leads in every scored category.\n\n### Do AccuWeather Core Weather API + MCP and meteoblue Weather API need an API key?\n\nBoth need an API key.\n\n### Can an agent call AccuWeather Core Weather API + MCP and meteoblue Weather API without installing anything?\n\nYes.
