API endpoints that return a list of domains (for eg, /api/domains/ip/:domain which returns a list of domains on a particular IP) can be paginated by using query parameters 'page' and 'limit'.
The following code will return 50 domains for the IP 8.8.8.8 starting from 250th.
curl "https://host.io/api/domains/ip/8.8.8.8?limit=5&page=5&token=$TOKEN"The max limit is 1000.
It's important to note that the maximum number of domains you can request is subject to your plan. For example, with free plan you can request maximum of 5 domains per page. Please check pricing page to see how many domains you can request per API call.
