Payment rails

A payment rail is where the provider asks to be paid. It is not proof that anything was paid through it. See evidence levels.

Examples are the provider's own, not a call we made.

Provenance

One row per statement. “Verified” means we checked it ourselves and the finding is quoted. “Provider claim” means we read it in the provider's own record. “Not found” is a statement about our search, not proof of absence.
