Trestle's RETS endpoint implements the RETS 1.8 specification on top of the same data catalog as the RESO Web API. The service is session-less; authentication uses HTTP Basic with client credentials or OAuth2 bearer tokens issued from /trestle/oidc/connect/token with scope=rets. Supported transactions include Login, GetMetadata, Search (up to 1000 records per request, default 10), and GetObject for media. The same RESO resources are exposed as RETS SearchType / Class names (Property, Member, Office, Teams, Media, Lookup). Digest authentication is not supported.
