Were the purchases worth it?

Keryx pays for sources before it knows whether they will help. This page scores those purchases against what was recorded afterwards: which bought articles the answer actually cited, and what the uncited ones cost.

Recorded bookkeeping only. Settlement is read from each run's retained trace and has not been rechecked against Circle or the chain here. Pending, simulated and failed payments are excluded.

A complete classified view is unavailable for this storage profile or period. Figures are withheld; nothing is inferred from the failure.
