GridVigil — common questions
Answered from what our own scheduled checks found, not from the provider's marketing.
Is GridVigil free to use?
GridVigil is listed in our free catalogue and required no credential when we called it. It needs no authentication at all, so you can send a request without signing up. Free tiers can still carry rate limits or non-commercial terms, so check the provider's own terms before shipping.
Does GridVigil need an API key?
No. We called GridVigil on our last run with no key, no token and no Authorization header, and it responded. That is what puts it in our no-key collection.
Can I call GridVigil from browser JavaScript?
Yes. GridVigil returned CORS headers when we checked it, so a browser will let your page read the response. You can fetch it directly from client-side JavaScript with no proxy and no backend.
Is GridVigil available over HTTPS?
Yes. GridVigil serves over HTTPS, so you can call it from a secure page without triggering a mixed-content block.
