  npm registry search, PyPI, the github.com/ercot organization, and the ERCOT developer portal
  code examples.

  ERCOT ships no client SDK for the Public Data API in any package registry. The developer portal
  documents the API with raw cURL / JavaScript fetch / Java HttpClient / Python requests snippets
  rather than a library, and the only first-party client code in the ERCOT GitHub organization is a
  Java SAMPLE client for the SOAP Web Services estate. Everything else that installs is
  third-party. Recorded here honestly: no `official: true` package exists in any registry, so no
  SDK count is claimed for ERCOT.
