payable

Decision procedure for when an x402 endpoint returns no payment terms: no 402 challenge, HTTP 404/405, or a weak merchant contract. Covers probe interpretation, knock-or-backoff thresholds, alternate rail fallback, retry budgets, and kill criteria, ending in a single verdict.

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