# Developer resources

> Find schemas, Script reference, and contract examples for your Agent API application

Use these resources when a build guide asks you to define contract XML, customize token behavior, or inspect an exact language feature. Start with the [Agent API quickstart](/neuron-api/quickstart) if you have not connected yet.
