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.

Response

string

Settings record UUID.

user_id

string

The user’s UUID.

max_per_call_atomic

integer

Maximum USDC per tool call in atomic units (6 decimals). Default: 5,000,000 ($5.00).

daily_limit_atomic

integer | null

Daily spending limit in atomic units. null means no daily limit.

created_at

string

ISO 8601 timestamp of when the settings were created.

updated_at

string

ISO 8601 timestamp of the last update.
