Where the offers sitLog scale. The shaded band is the middle half of the market, $0.0020 to $0.010.
$0.0010$1.00

Every supplier below carries its index against that rate: 100 is spot, 40 is 60% below it, 310 is 3.1× it. Spot is weighted by how often each endpoint is called, so one wallet listing forty near-identical endpoints cannot move it on listings alone. The cheapest offer here is $0.0010 and the dearest $1.00.
