List catalog models
List the models available in the SLNG catalog. Supports filtering by service type, provider, region, language, use case, capability, and protocol, plus full-text search and pagination. Authentication is optional — an API key personalizes pricing and region availability for your organisation; anonymous requests return public catalog data.
