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**WeatherAPI.com.** 3 million calls for $7 a month, and 100,000 a month free with no card. Key only in the query string, and no security.txt.\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### WeatherAPI.com\n\n1. Pass current_fields, day_fields or hour_fields to cut the response to what you need\n2. Treat a 403 with error code 2007 as the monthly quota, not a bad key. There's no 429\n3. Reuse the id from search.json (q=id:NNN) to avoid ambiguous city names\n4. Cache history freely, current for under an hour and forecasts for under a day, to stay inside the terms\n5. Use https://api.weatherapi.com/v1. The docs still show an http:// base URL\n\n## Questions\n\n### Which is better for AI agents, meteoblue Weather API or WeatherAPI.com?\n\nWeatherAPI.com scores 65.3 (B) on agent readiness against meteoblue Weather API's 61.7 (C), and leads in 4 of 7 scored categories. meteoblue Weather API leads on security \u0026 auth and maintenance \u0026 community.\n\n### Do meteoblue Weather API and WeatherAPI.com need an API key?\n\nBoth need an API key.\n\n### Can an agent call meteoblue Weather API and WeatherAPI.com without installing anything?\n\nYes. meteoblue Weather API has a hosted endpoint at https://my.meteoblue.com and WeatherAPI.com at https://api.weatherapi.com/v1.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/meteoblue-vs-weatherapi-com.json, and with the fewest tokens: https://www.anchorterminal.com/compare/meteoblue-vs-weatherapi-com.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"meteoblue\", \"b\": \"weatherapi-com\"}`.
