No OpenAPI, llms.txt, SDK or MCP server.\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### Met Office Weather DataHub (Site Specific)\n\n1. Register an application and subscribe it to the Global Spot plan first. The key is tied to that order and shown once\n2. Send the key in the apikey header with Accept: application/json, and latitude and longitude as query parameters\n3. Add excludeParameterMetadata=true to drop the parameter descriptions from every response\n4. Pick the timestep by need. hourly covers 48 hours, three-hourly 168, daily 7 days, and each call counts against the daily limit\n5. Stop on a 429.
