  note: >-
    Probed on 2026-07-27 — PJM publishes no CLI or SDK package to npm, PyPI, Maven
    Central, RubyGems, NuGet, crates.io, Packagist or pkg.go.dev, and operates no
    GitHub organisation (github.com/pjm-interconnection returns 404 and the GitHub
    org search for "PJM Interconnection" returns zero results).
capabilities:
- Authenticate to PJM with a PJM Tools credential and obtain the SSO session used by OASIS.
- Submit NAESB WEQ-002 query/response and input/response templates.
- Retrieve template responses for scripted/scheduled use.
- Exercise the three PJM custom templates (pjmannulment, pjmtransreq, pjmtsrcomment).

note: >-
  The command surface (exact flags and subcommands) is documented inside the OASIS
  API User Guide PDF and inside the distributed ZIP; it is not published as a
  standalone reference page, so no command tree is transcribed here rather than
  guessed. There is no first-party CLI for Data Miner 2 — that surface is driven with
  plain HTTP plus the subscription key.
