  ISO New England ships NO first-party client library, SDK or CLI in any language. The GitHub
  organization github.com/iso-ne exists but has 0 public repositories, the Web Services Data page
  offers only documentation and a spreadsheet, and searches of npm and PyPI on 2026-07-27 returned
  no ISO New England-published package. The libraries listed below are third-party, community or
  vendor projects that read ISO New England data; they are recorded as leads for developers, and
  every one is marked official:false. No SDKs pointer is claimed for this provider.

not_searched_note: >-

  link in ISO New England's documentation, no first-party package is expected on the remaining
  registries. Recorded honestly rather than claimed as exhaustive.
