Rate Limit Check

Here are the HTTP headers and response when fetching api. Note the x-ratelimit-* headers.

Headers

When you reload the page, x-ratelimit-remaining will reduce by 1, and x-ratelimit-reset will reflect the number of seconds to reset.

Response

Try with a different key

In this example, every "key" parameter has an independent rate limit. Type a random string and submit. You'll see a new rate limit queue set up.
