Rate limiting and Expiration Header

[Karasu.9483]

Wanted to continue a discussion on this topic and get some answers to questions I have:

 

1. [Listings are cached for 30 seconds but can only be polled every 20 minutes?](https://forum-en.guildwars2.com/forum/community/api/HEADS-UP-rate-limiting-is-coming/page/2#post6748536 )

2. Some endpoints like [delivery](https://wiki.guildwars2.com/wiki/API:2/commerce/delivery "https://wiki.guildwars2.com/wiki/API:2/commerce/delivery") are cached server-side but do not contain an expiration header. What is the rate for these and could you add the expiration header to these endpoints?

Everything that returns account/character info is cached between 5-10 minutes (range depends on whether you're logged in or not).

 

You can fetch multiple listing entries by using the pagination parameters (e.g., `?page_size=200&page=N`). IIRC the rate limit is set up so you can pull all the listing data every minute or so using the paginated requests.
