description: 'Real ISO New England response payloads, observed anonymously on 2026-07-27. ISO New England
  publishes no example payloads with its documentation, and the REST API itself answers 401 without ISO
  Express credentials - but the public ISO Express dashboards are fed by an anonymous JSON proxy at https://www.iso-ne.com/ws/wsclient
  that returns the same resource paths as the authenticated Web Services API. Each file below is the payload
  that proxy returned for the named resource path, with the proxy envelope ([{"data": ...,"namespace":"_nstmp_"}])
  and its injected _url key removed. Nothing was edited or synthesised. Values are a real system snapshot
  from 2026-07-27 and are not stable data - they are examples of shape, not of content. These same payloads
  are wired as response examples in openapi/iso-new-england-web-services-openapi.yml.'
caveat: The wsclient proxy is undocumented and unsupported by ISO New England. It is used here only as
  an evidence source for payload shape; developers should use the documented API at https://webservices.iso-ne.com/api/v1.1
  with ISO Express credentials.
