GET /api/buy/spot_check
402-malformed
Spot Check. REQUIRES ?host= on the paid request — a signed request without it is refused before the gate and no money moves. Name a host and get what this observatory already holds on it, signed: corpus rounds and verdicts as recorded, when we last actually knocked, our coverage of the window since we met it, and the gaps with their reasons. Read from the books at the counter — no request is made…
Verdict: not verified by an unpaid GET. 402 without a usable accepts list. This says nothing about whether the route works when called as declared.
