Terms forbid using the data to train, validate or otherwise inform any AI system.\n\n**The Weather Company Data APIs.** A wide weather data API with 168 API references built from OpenAPI documents, global 4 km current conditions, hourly history from June 2015 and a status page with component history. Keys come only through a sales-reviewed trial or contract, travel only in the URL, and the terms that govern the API are not published.\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### The Weather Company Data APIs\n\n1. Send `units`, `language` and `format=json` with a location on every v3 call, plus `Accept-Encoding: gzip`, which the usage guide marks as required.\n2. Keep the key out of logs and client-side code, because it travels in the query string as `apiKey`.\n3. Treat a 401 as either a bad key, an endpoint outside the key's package or an exceeded limit, and treat a 204 as no data for the query.\n4. Each forecast duration (`3day` to `15day`) is a separate entitlement. Request only durations the contract covers.\n5. Use `/v3/aggcommon` to combine up to 10 products in one request. Each product and each location still counts as one call.\n\n## Questions\n\n### Which is better for AI agents, AccuWeather Core Weather API + MCP or The Weather Company Data APIs?\n\nThe Weather Company Data APIs scores 52.6 (D) on agent readiness against AccuWeather Core Weather API + MCP's 48.4 (D), and leads in 4 of 7 scored categories. AccuWeather Core Weather API + MCP leads on agent ergonomics, payments \u0026 pricing and transparency \u0026 trust.\n\n### Do AccuWeather Core Weather API + MCP and The Weather Company Data APIs need an API key?\n\nBoth need an API key.\n\n### Can an agent call AccuWeather Core Weather API + MCP and The Weather Company Data APIs without installing anything?\n\nYes.
