Trestle Participant Reporting API
A compliance API that lets technology providers report to each MLS which brokers they hold contracts with — the mechanism by which the licence relationship behind a data feed is evidenced. Documented operations are POST and GET on /trestle/report/TpParticipantReport, authenticated with the same OAuth2 client_credentials flow as the Web API (scope=api for Web API feeds, scope=rets for RETS feeds). Not every MLS uses it; some require individual contracts hosted in Trestle instead.
