Unless otherwise stated, all APIs in the APILayer ecosystem have rate-limiting enabled.
The following headers are sent every time a request is made, showing you the number of requests left in your subscribed plan.
X-RateLimit-Limit-Day: 1000 X-RateLimit-Limit-Month: 30000 X-RateLimit-Remaining-Day: 997 X-RateLimit-Remaining-Month: 29873
If you require more/less requests, you can upgrade/downgrade your plan at any time from the "Subscriptions" page.
Once you reach the limit, the API server sends a response with HTTP code 429.
You can see the usage in the "API Detail" page as well.
