answers 402

Bundled execution of the Cross-asset price monitor workflow - Side-by-side snapshot of a stock and a crypto asset: live quotes, 1-year history, and a date-stamped comparison. One x402 payment runs 5 underlying tools (stock-quote, stock-history, crypto-price, crypto-history, date-format); partial-success per step.

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