GET /api/v1/markets/mispriced

unprobed

Use this to rank covered markets where Quotient's probability differs from a verified live venue quote. The endpoint batches live reads, then applies the odds band, spread threshold, direction, and sort to one selected quote. Missing, stale, and unsupported live quotes are excluded. Returns quote provenance, routing, Q probability, spread, thesis, and venue-reported volume.

Verdict: not verified by an unpaid GET. not probed yet. This says nothing about whether the route works when called as declared.
