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**Open-Meteo.** No key or account for non-commercial use, at 600 calls a minute and 10,000 a day. Commercial prices appear only at Stripe checkout.\n\n## Before you call either\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### Open-Meteo\n\n1. Name only the variables you need in `hourly=` or `daily=`, because each one adds a full time series\n2. Credit 'Weather data by Open-Meteo.com' wherever you show the data\n3. Use customer-api.open-meteo.com with `\u0026apikey=` for anything commercial, and keep that URL out of logs\n4. Read `reason` on a 400. It names the bad parameter\n5. Cache by coordinate and model run, since global models update about every six hours\n\n## Questions\n\n### Which is better for AI agents, Meteomatics Weather API or Open-Meteo?\n\nOpen-Meteo scores 63.4 (B) on agent readiness against Meteomatics Weather API's 49.6 (D), and leads in 6 of 7 scored categories. Meteomatics Weather API leads on security \u0026 auth.\n\n### Do Meteomatics Weather API and Open-Meteo need an API key?\n\nMeteomatics Weather API takes an API key or an OAuth sign-in. Open-Meteo needs no key.\n\n### Can an agent call Meteomatics Weather API and Open-Meteo without installing anything?\n\nYes. Meteomatics Weather API has a hosted endpoint at https://api.meteomatics.com and Open-Meteo at https://api.open-meteo.com/v1/forecast.\n\n### Are Meteomatics Weather API and Open-Meteo open source?\n\nNo open-source release is listed for Meteomatics Weather API. Open-Meteo is open source (AGPL-3.0 (code), CC BY 4.0 (data)).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/meteomatics-vs-open-meteo.json, and with the fewest tokens: https://www.anchorterminal.com/compare/meteomatics-vs-open-meteo.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"meteomatics\", \"b\": \"open-meteo\"}`.
