# Cross-signal consistency APIs compared

Cross-signal consistency has no comparable vendor to put in a table: what Spaw answers, what it costs, and where the comparisons for the other signals are.

Any subset of the email, phone, IP and address signals in one call, with the agreements and disagreements between them named and both sides quoted. No score, no verdict, no recommendation.

No other vendor publishes a comparable product, so there is no table on this page. What follows is what Spaw answers, what it costs, and where to find the comparisons for the signals that do have them.
