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**Stormglass API.** A read-only weather and marine API with about 70 hourly parameters, per-source values from named national models, tide data and ERA5 history from 2014. No OpenAPI file, status page, SDK or security page was found, the free plan allows 10 requests a day, and the docs and FAQ disagree on the status code for a spent quota.\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### Stormglass API\n\n1. Send the key as `Authorization: KEY` with no Bearer prefix. A missing or wrong key returns 403 with `{\"errors\":{\"key\":\"API key is invalid\"}}`\n2. Always pass `source=sg` or a short source list on `/weather/point`. The default is every source, which multiplies the size of each hourly record\n3. Treat 402 as a spent daily quota, not a billing failure, and stop until the next day. Read `meta.requestCount` against `meta.dailyQuota` on each response\n4. Use `/historical/point` for past dates, at most 10 days a call and nothing newer than about 7 days. `/weather/point` looks back 14 days only\n5. Send and read all times in UTC. Tide sea levels are relative to the chosen datum (MSL by default) and are not water depth\n\n## Questions\n\n### Which is better for AI agents, meteoblue Weather API or Stormglass API?\n\nmeteoblue Weather API scores 61.7 (C) on agent readiness against Stormglass API's 39.9 (E), and leads in every scored category.\n\n### Do meteoblue Weather API and Stormglass API need an API key?\n\nBoth need an API key.\n\n### Can an agent call meteoblue Weather API and Stormglass API without installing anything?\n\nYes. meteoblue Weather API has a hosted endpoint at https://my.meteoblue.com and Stormglass API at https://api.stormglass.io/v2.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/meteoblue-vs-stormglass.json, and with the fewest tokens: https://www.anchorterminal.com/compare/meteoblue-vs-stormglass.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"meteoblue\", \"b\": \"stormglass\"}`.
