Abstract: A system receives a selection, by a first entity, of product, provided by a second entity, wherein the first entity and the second entity are members of an entity network. The system receives an indication of receipt of the product via an application programming interface (API), transmitted by a first entity, and derives a first ranking metric for the second entity of the entity network based on feedback received from the first entity of the entity network. The system derives a second ranking metric for the second entity of the entity network based on one or more transactions received from a third entity of the entity network, determines whether the first ranking metric is valid based on the second ranking metric, and provides the first ranking metric to entities of the entity network based on the validity of the first ranking metric.
