Use this to rank covered markets where Quotient's probability differs from a verified live
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.
