You can restrict API access so that it only works from your addresses. This is the main protection for your key.
Steps to follow
In the left menu, open the "API" section.
In the address field, specify the IPs from which you will access the API. List multiple addresses separated by commas.
Click "Submit".
Allowed addresses field and save button. 1 — "Do not share this key with anyone" · 2 — "Generate key" · 3 — insert · 4 — "Submit"
What are the restrictions
No more than 3 IP addresses.
No more than 60 requests per minute.
If the request limit is exceeded, the API will return an error instead of data — in this case, reduce the frequency of requests.
Please note. If your server changes its address, access to the API will be lost. Don't forget to update the list of allowed addresses.
