Guild Wars 2

Hi.

I searched around this forum a bit but didn’t find any answers to my question, so here goes.

I’m quite new to web apis so this might be a trivial question, but what constitutes fair use of the api from a load position? For example if I’d like to create my own historical database of the trades of a couple of items, what kind of resolution (ie. api poll frequency) can I go down to before it becomes an issue?

See this thread: https://forum-en.gw2archive.eu/forum/community/api/How-frequently-is-it-OK-to-access-the-API/2815206

Thanks, and sorry for the repost.

But if I spam refresh on Silk Scrap url https://api.guildwars2.com/v2/commerce/listings/19748 I can clearly see that the values update every 5 minute or so as well, and not at the same pace I can see them changing in-game.
