How Missouri Certified Respiratory Therapist license verification works

A Certified Respiratory Therapist in Missouri is licensed by the MO Respiratory Care Board. PrimaryCheck looks the license up live at the board's public verification system (board lookup) by license number, or by name when no number is supplied. The record the board publishes is captured as evidence, hashed, and rendered into a proof PDF.

`name`	Last name or declared alias matches; first name exact or nickname
`license_type`	The record is a Certified Respiratory Therapist license, strictly (no near-miss types)
