League SDK

Typed TypeScript SDK for Riot LoL API. Handles routing, PUUID conversions, rate limiting.

LoL API Concepts

Scope: This SDK covers League of Legends only. TFT, Valorant, Wild Rift have separate APIs.

PUUID: Universal ID across Riot games. Preferred over SummonerId/AccountId (deprecated).

Platform: Use player's server (kr for Korean, euw1 for EU West). Wrong platform = 404.

Queue IDs: 420 Solo/Duo, 440 Flex, 450 ARAM, 400 Normal Draft, 430 Blind

Timestamps: Unix epoch milliseconds → new Date(match.gameCreation)

Match history: Riot retains ~2 years. Older matches may be unavailable.
