Hi, it’s currently impossible to find the PvP item level of a character. The “Character Equipment Summary” endpoint provides the PvE item level, so it would be natural to have the PvP item level here as well. The in-game LFG system also displays a character’s overall PvP item level (not per item), which would be a viable to expose as well, if effort is lower.
Knowing the strength of a character is essential information for almost all use cases of the API for WoW PvP, so this would be an amazing feature.
