Environment

Name	Required	Notes
THREE_WS_SESSION	No	Your three.ws session token (value of the `__Host-sid` cookie from a signed-in browser). Required for account management operations: create_payment_session, list_payment_sessions, check_payment_session, cancel_payment_session. Secret.
PAYMENT_SESSION_TOKEN	No	A payment session bearer token (starts with 'pss_') from create_payment_session. Used by the agent for pay_with_session calls when no inline token is passed. Treat like a spending card — it authorizes payments up to the session's budget. Secret.
THREE_WS_BASE	No	Base URL of the three.ws API. Override only when self-hosting or targeting a preview deployment.
THREE_WS_TIMEOUT_MS	No	Per-request HTTP timeout in milliseconds. x402 payments involve on-chain settlement so this should be generous (default: 30000).
