Access needs a sales contract, with no public price, free tier or self-serve signup found, no status page, and REST calls that authenticate with a username and password.\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### Meteomatics Weather API\n\n1. Ask the account owner for credentials first. There is no signup, and both the REST API and the MCP server need a Meteomatics account with API access\n2. Build REST URLs as validdatetime/parameters/location/format, for example `2026-10-08T00:00:00Z/t_2m:C/52.52,13.40/json`. Parameter names carry their unit after a colon\n3. Keep each query to 10 locations and 10 parameters unless the contract says otherwise, and use POST when a GET URL passes 2,000 characters\n4. Send credentials or the token in the `Authorization` header. Avoid the documented `access_token` query parameter, which puts the token in URLs and logs\n5. Read `/user_stats_json` before a large job. It reports queries sent and the contract's limits, and 429 means a limit is spent\n6. Treat reserved values such as -888 and -999 as invalid or missing data, and shrink the request when a 408 arrives after the 300-second timeout\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, Meteomatics Weather API or Stormglass API?\n\nMeteomatics Weather API scores 49.6 (D) on agent readiness against Stormglass API's 39.9 (E), and leads in 5 of 7 scored categories. Stormglass API leads on payments \u0026 pricing.\n\n### Do Meteomatics Weather API and Stormglass API need an API key?\n\nMeteomatics Weather API takes an API key or an OAuth sign-in. Stormglass API needs an API key.\n\n### Can an agent call Meteomatics Weather API and Stormglass API without installing anything?\n\nYes. Meteomatics Weather API has a hosted endpoint at https://api.meteomatics.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/meteomatics-vs-stormglass.json, and with the fewest tokens: https://www.anchorterminal.com/compare/meteomatics-vs-stormglass.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"meteomatics\", \"b\": \"stormglass\"}`.
