answers 402

The x402 Router: send a plain-English goal in q (e.g. 'audit https://api.example.com/paid', 'price of eth', 'is 0x… a contract', 'verify settlement 0x…') and Quartermaster picks the right tool from its full toolkit, runs it, and returns the answer plus which tool it used. One endpoint for anything x402, crypto-on-Base, or web/AI.

We sent a real GET request to this endpoint and it answered 402 with payment requirements we could parse.
