How do I get a Riot Games API key?

Register at [**developer.riotgames.com**](https://developer.riotgames.com/) and sign in with your Riot account to get your personal development API key. It's free and works immediately.

PUUID (Player Universally Unique Identifier) is a unique ID assigned to every Riot account. It's required for most API calls like match history and champion masteries. Get it using get_account_by_riot_id with the player's game name and tag line.

What are platform codes?

Platform codes identify specific game servers: na1 (North America), euw1 (Europe West), eun1 (Europe Nordic & East), kr (Korea), br1 (Brazil), jp1 (Japan), la1/la2 (Latin America), tr1 (Turkey), oc1 (Oceania). Match history uses regional routing instead: americas, europe, asia, sea.

What are the API rate limits?

Development API keys are limited to 20 requests per second and 100 requests per 2 minutes. If you exceed these limits, the API returns a 429 error. Wait a moment and retry.
