safe4_price
Price and accepted payment networks for one Safe4 decision. Free to call. Returns the same x402 terms the HTTP endpoint advertises, so an agent can see the cost before committing to a paid call.
safe4_authorize
Decide whether a proposed agent payment should proceed. Settled per call in USDC over x402. Called without ``payment`` it returns the price list rather than a decision; call it again with the signed payload to receive one. The task and the two allow-lists are the principal's constraints, not the age
