Session price escalation
Quirk · GET /api/x402/session-price-escalation · Client Policy Gate (MCP)
The price climbs call over call (1x, 2x, 3x...) to defeat a per-session spend limit.
Explanation
The advertised price climbs on every call within a session (1x, 2x, 3x...), so each individual charge may slip under a per-call cap while the cumulative spend balloons. Unlike changing-price, the goal is to defeat a per-session budget. A correct client policy gate tracks per-session spend and rejects once the running total exceeds the limit.
What to watch
Each call may slip under a per-call cap, but a per-session budget check catches the running total.
