Filter monsters by XP

[SansCB]

Hello! I am trying to filter with an API call all the monsters that have an XP value, but it returns all the monsters. I'm doing it like this:
https://www.dnd5eapi.co/api/monsters?xp=200

Testing with other indexes, such as challenge_rating, it does work:
https://www.dnd5eapi.co/api/monsters?challenge_rating=10

I don't know if this is a bug, or I'm doing something wrong using the API.

I don't think we have an XP filter for monsters, but in D&D 5e, XP is a function of Challenge Rating (CR, the challenge_rating field). That is, all monsters with a challenge rating of 1 give 200xp, CR 2 always gives 450xp, etc.

So instead, you can filter by CR like you're already doing. So for monsters that give 200xp, you can do the following:

Note that for CR ½ and ¼ you should use the values 0.5 and 0.25 respectively.
