A public Pingdom page shows monthly uptime per API. The key travels only in the query string, the free trial covers nine forecast packages, and no security.txt, certification or DPA was found.\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### meteoblue Weather API\n\n1. Pass `lat`, `lon` and `apikey` to `https://my.meteoblue.com/packages/\u003cpackage\u003e`. Join packages with commas, such as `basic-1h,basic-day`, to get several in one call\n2. Budget credits before calling. One call costs 4,000 to 96,000 credits by package, and the free trial holds 10 million for a year. Read `MB-Credits-Accounted` on each response\n3. Set `forecastDays` and pick the coarsest resolution that does the job. Without it the API returns every forecast day it has\n4. Call with a 30-second timeout, wait 30 seconds after an error and stop after 10 retries, as the availability page advises. The default limit is 500 calls a minute\n5. Keep the key out of logs, since it is part of every URL. Ask for a shared secret and send `expire` and `sig` if URLs may be seen by others\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, meteoblue Weather API or The Weather Company Data APIs?\n\nmeteoblue Weather API scores 61.7 (C) on agent readiness against The Weather Company Data APIs's 52.6 (D), and leads in every scored category.\n\n### Do meteoblue Weather API and The Weather Company Data APIs need an API key?\n\nBoth need an API key.\n\n### Can an agent call meteoblue Weather API and The Weather Company Data APIs without installing anything?\n\nYes. meteoblue Weather API has a hosted endpoint at https://my.meteoblue.com and The Weather Company Data APIs at https://api.weather.com.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/meteoblue-vs-weather-company.json, and with the fewest tokens: https://www.anchorterminal.com/compare/meteoblue-vs-weather-company.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"meteoblue\", \"b\": \"weather-company\"}`.
