Terms forbid using the data to train, validate or otherwise inform any AI system.\n\n**Meteomatics Weather API.** A public OpenAPI file, a hosted MCP server whose nine tools are all marked read-only, a published SLA with compensation and ISO 27001 certification suit company use. Access needs a sales contract, with no public price, free tier or self-serve signup found, no status page, and REST calls that authenticate with a username and password.\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### Meteomatics Weather API\n\n1. Ask the account owner for credentials first. There is no signup, and both the REST API and the MCP server need a Meteomatics account with API access\n2. Build REST URLs as validdatetime/parameters/location/format, for example `2026-10-08T00:00:00Z/t_2m:C/52.52,13.40/json`. Parameter names carry their unit after a colon\n3. Keep each query to 10 locations and 10 parameters unless the contract says otherwise, and use POST when a GET URL passes 2,000 characters\n4. Send credentials or the token in the `Authorization` header. Avoid the documented `access_token` query parameter, which puts the token in URLs and logs\n5. Read `/user_stats_json` before a large job. It reports queries sent and the contract's limits, and 429 means a limit is spent\n6. Treat reserved values such as -888 and -999 as invalid or missing data, and shrink the request when a 408 arrives after the 300-second timeout\n\n## Questions\n\n### Which is better for AI agents, AccuWeather Core Weather API + MCP or Meteomatics Weather API?\n\nMeteomatics Weather API scores 49.6 (D) on agent readiness against AccuWeather Core Weather API + MCP's 48.4 (D), and leads in 5 of 7 scored categories. AccuWeather Core Weather API + MCP leads on reliability and payments \u0026 pricing.\n\n### Do AccuWeather Core Weather API + MCP and Meteomatics Weather API need an API key?\n\nAccuWeather Core Weather API + MCP needs an API key. Meteomatics Weather API takes an API key or an OAuth sign-in.\n\n### Can an agent call AccuWeather Core Weather API + MCP and Meteomatics Weather API without installing anything?\n\nYes. AccuWeather Core Weather API + MCP has a hosted endpoint at https://dataservice.accuweather.com and Meteomatics Weather API at https://api.meteomatics.com.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/accuweather-api-vs-meteomatics.json, and with the fewest tokens: https://www.anchorterminal.com/compare/accuweather-api-vs-meteomatics.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"accuweather-api\", \"b\": \"meteomatics\"}`.
