Open a budget-capped agent session on AgentPay.
AI agents use session_create to commit financial operations through AgentPay x402 — Economic-intelligence layer for AI Agents — usually the final step of a payment, billing, or trading workflow. A call moves real money.
Creating a session on AgentPay directly initiates a financial arrangement where USDC is allocated/committed for pay-per-call tool usage on Stellar. Even though it is 'budget-capped', it represents a financial obligation and enables subsequent monetary transactions, placing it in the Financial category.
From the tool's definition 'Open a budget-capped agent session on AgentPay' — establishes a financial session committing USDC funds on Stellar; 'Agents pay USDC on Stellar' and 'Budget-aware sessions' confirm financial commitment
