# Get Spending Limits

> Get the current user's USDC spending limit settings

## Overview

Returns the user's x402 spending limit configuration, including per-call maximum and optional daily spending cap. These limits control how much USDC can be spent on paid tool executions.

The platform enforces a hard cap of \$5.00 (5,000,000 atomic units) per tool call regardless of user settings.

**Authentication:** Requires JWT token or API key.
