Axie Experience Points (AXP) is a global, ecosystem-wide progression system for Axies. By integrating the AXP service, you can issue AXP to Axies in your game or dApp. This lets you connect your game to the Axie ecosystem and attract players to your game.
AXP is an off-chain token that is gained by Axies through gameplay and other various Axie experiences. Levels are on-chain numbers that are mapped to each Axie, while ascension is a mechanism where users need to sign an on-chain transaction for an Axie to advance to certain levels, at 10, 20, and 30, respectively.
The AXP service provides a REST API. To start integrating with the API, see Get started.
