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**Visual Crossing Weather API.** History from 1970, current conditions and a 15-day forecast from one endpoint. Key only in the query string on the REST API.\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### Visual Crossing Weather API\n\n1. Always pass include= and elements=. A bare call returns days, hours and current for every element and burns records\n2. Count records before a backfill. Hourly data is 24 records a day, so a year for one place is 8,760\n3. Pass unitGroup=metric. The default is US units\n4. Use the MCP server with X-VC-API-Key rather than pasting the key into a URL\n5. Keep to one request at a time on Free and Professional. A second concurrent job returns 429\n\n## Questions\n\n### Which is better for AI agents, Meteomatics Weather API or Visual Crossing Weather API?\n\nVisual Crossing Weather API scores 59.9 (C) on agent readiness against Meteomatics Weather API's 49.6 (D), and leads in 4 of 7 scored categories. Meteomatics Weather API leads on security \u0026 auth.\n\n### Do Meteomatics Weather API and Visual Crossing Weather API need an API key?\n\nMeteomatics Weather API takes an API key or an OAuth sign-in. Visual Crossing Weather API needs an API key.\n\n### Can an agent call Meteomatics Weather API and Visual Crossing Weather API without installing anything?\n\nYes. Meteomatics Weather API has a hosted endpoint at https://api.meteomatics.com and Visual Crossing Weather API at https://weather.visualcrossing.com/VisualCrossingWebServices/rest/services/timeline.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/meteomatics-vs-visual-crossing.json, and with the fewest tokens: https://www.anchorterminal.com/compare/meteomatics-vs-visual-crossing.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"meteomatics\", \"b\": \"visual-crossing\"}`.
