Using IPs for securing assets is not recommend, as these addresses will change over time without notice.
Instead, the recommended approach is to use HTTP basic auth over HTTPS or prince_options[http_proxy]. This API is provided if no other alternative is available.
Use this endpoint to get a list of IP addresses that DocRaptor currently uses to download assets.
You can make a GET request against the following URLs:
https://docraptor.com/ips.txtfor a txt formatted response
https://docraptor.com/ips.jsonfor a json formatted response
