How to carry out high-frequency parsing of sites?

Question

.NET

Hello everyone
Please tell me which way it will be easier and faster to solve the following problem: It is
necessary to parse many pages from one site with a fairly high frequency, and there are risks that this will be perceived as a small DDoS attack, are there any services that can to implement it?
For example, parsing 20 pages of a site once a second, and I get all this with one request from this service? I was looking for such - I didn’t find it, maybe some other ways tell me (on the .net platform)?
Thanks in advance.
upd:
found one https://import.io/ , who else knows?
