… upstream calls
Answer a disputed fill in ninety seconds, with the venue's own tape as the evidence.
Four things a Paxos support engineer does on a Tuesday: verify a client's fill against the public tape, price the slippage their order size was always going to cost, watch every listed market for the degradation that produces tomorrow's tickets, and hand engineering a reproducible API defect instead of a complaint.

Client's reported fill
Only markets with a retrievable order book are listed. That subset is itself a finding, see the contract checks tab.
What this can and cannot prove. It checks a reported price against the public tape and the current book. That is enough to close most disputes, and it is not the order-level record. Where the answer is "no print at that level in this window", the console says so and drafts the escalation rather than guessing.
Run an investigation to see the verdict, the evidence, and a drafted reply.
