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**Pirate Weather.** Named model sources and a documented priority order for every field. No SLA, and the terms call it best effort.\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### Pirate Weather\n\n1. Send the key in an apikey header and put a placeholder in the path so it stays out of logs\n2. Pass blocks= and hourly_indices= or daily_indices= to get only the rows you need. The default payload is large\n3. Ask for version=2 to get fields Dark Sky never had, such as smoke, fire index and the source list\n4. Point historical requests at timemachine.pirateweather.net with a UNIX timestamp after the coordinate\n5. Watch Ratelimit-Remaining. The cap is monthly, so a runaway loop can spend it in a day\n\n## Questions\n\n### Which is better for AI agents, meteoblue Weather API or Pirate Weather?\n\nPirate Weather scores 65.9 (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.\n\n### Do meteoblue Weather API and Pirate Weather need an API key?\n\nBoth need an API key.\n\n### Can an agent call meteoblue Weather API and Pirate Weather without installing anything?\n\nYes. meteoblue Weather API has a hosted endpoint at https://my.meteoblue.com and Pirate Weather at https://api.pirateweather.net/forecast.\n\n### Are meteoblue Weather API and Pirate Weather open source?\n\nNo open-source release is listed for meteoblue Weather API. Pirate Weather is open source (Apache-2.0 (docs and spec), AGPL-3.0 (API code)).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/meteoblue-vs-pirate-weather.json, and with the fewest tokens: https://www.anchorterminal.com/compare/meteoblue-vs-pirate-weather.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"meteoblue\", \"b\": \"pirate-weather\"}`.
