Quant Agent Shop

Free, no payment. Send the name of any paid tool here, and optionally the arguments you plan to send; returns its price, network and payTo address (the same terms its 402 gives) and whether the arguments are valid, with the errors if not. Nothing runs upstream. With a pilot key in _meta pilot-key, also says whether the key is valid for that tool and how much of today's allowance (in list price) is left.
