~~Most~~ ESI endpoints ~~don't have~~ rate-~~limits, but are error-limited instead, meaning~~ an ~~ESI application is blocked if it makes too many erroneous requests. However~~, ~~there are two notable exceptions: The <code>characters/{character_id}/corporationhistory/</code>~~ and the ~~<code>markets/{region_id}/history/</code> endpoints have rate limits~~ of ~~300 requests per IP per minute.<ref>EVE Forums: [https://forums.eveonline.com/t/resolved-esi-characters-corporation-history/391132/27 Resolved - ESI Characters Corporation History] (2023-08-25~~)~~</ref><ref>Dev blog: [https://www.eveonline.com/news/view/eve-evolved-~~the~~-future-of-eves-api EVE Evolved: The Future of EVE’s API] (2025-02-27)</ref> This rate limit is unfortunately not documented in~~ the ~~ESI docs~~.

ESI endpoints now use a Token system for rate limiting - each hit on an endpoint uses up a token, and if attempted to often (usually at a rate faster than the cache time of the endpoint) the caller will be limited until the next hour when tokens refresh.

Eve uses a lot of 'ID's, that are unique for things. Ships, players, corporations, systems all have unique IDs. Most IDs are arranged in 'Ranges' as well. Comparing IDs against these ranges to find out what type of ID it is. https://developers.eveonline.com/docs/guides/id-ranges/ has these ranges listed out. Figuring out what an ID is can answer many questions of what ESI to find out what it is. There are two very fast ways to find Names for IDs as well. Linking a thing in chat, then hit enter, then right click, and copy. This will put the URL code in the clipboard. Alternately, go to a site like https://zkillboard.com/ and the ID will be at the end. Ex: https://zkillboard.com/ship/22460 the Eris id is 22460. See also [[How to get ID]]
