How to call it
A starting template for Stormglass. Replace ENDPOINT with the path from the official documentation, which we link above rather than guess at.
# Requires an API key. Check the docs for whether it goes in a header or a query parameter.
curl -s "https://docs.stormglass.io/ENDPOINT" \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Accept: application/json"This API does not send CORS headers, so a browser will block a direct call from your front end. Call it from your server, or put a small proxy in front of it.

Stormglass — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is Stormglass free to use?
Stormglass is listed in our free catalogue, but it requires an API key, so you will need to register before your first call. Providers frequently reserve higher limits and commercial use for paid plans.
Does Stormglass need an API key?
Yes. Stormglass authenticates with an API key. Keep it server-side rather than in browser code, because anything in your frontend bundle is readable by anyone who opens developer tools.
Can I call Stormglass from browser JavaScript?
Not directly. Stormglass did not return CORS headers when we checked, so the browser will block your page from reading the response even though the request itself succeeds. Call it from a server, or put a small proxy in front of it.
Is Stormglass still working?
Yes, as of 2026-09-18. Our automated check reached Stormglass and recorded a 100% reliability score with a median response time of 720 ms. We re-check on a schedule, and this page updates with the result.
Is Stormglass available over HTTPS?
Yes. Stormglass serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
