  Yes Energy is a Boulder, Colorado power market data company serving
  the North American wholesale electricity markets — the seven ISOs and RTOs
  (ERCOT, PJM, MISO, CAISO, SPP, ISO-NE, NYISO) plus Canadian and Western
  markets. It aggregates, cleans, and enriches nodal locational marginal prices,
  FTR auction results, transmission and generation outages, real-time generation
  and flow telemetry, constraints, load, weather, and fuels data, and sells it
  through DataSignals (a REST API), DataSignals Cloud (Snowflake Secure Data
  Sharing), DataSignals Lake (bulk load into a customer warehouse), the
  PowerSignals and QuickSignals analyst front ends, EnCompass modeling, Live
  Power telemetry, Infrastructure Insights, Position Management, and bid-to-bill
  Submission Services. It sits in the private, commercial layer of the energy
  value chain: it does not generate, distribute, or retail electricity and it
  holds no consumer relationship — it resells and enriches public ISO/RTO market
  data to traders, IPPs, utilities, and asset developers. Its API posture is
  honestly closed: the DataSignals REST API is real and confirmed live at
  https://services.yesenergy.com/PS/rest/, but it answers every anonymous
  request with HTTP 401 and WWW-Authenticate Basic, and even the product
  documentation (help.yesenergy.com) redirects through
  services.yesenergy.com/PS/KnowledgeOwlAuthentication to a customer login. No
  public developer portal, no self-serve signup, no machine-readable
  specification, and no free tier are published. Home market is the United
  States. There is no consumer energy data mandate that applies to Yes Energy —
  it is not a utility, retailer, or metering agent, so Green Button, ESPI, and
  the Consumer Data Right are all out of scope — and while the underlying
  ISO/RTO market data is publicly available at the source, Yes Energy itself
  publishes none of it openly.

    DataSignals is Yes Energy's REST API for automated access to its
    North American wholesale power market data — nodal prices, transmission,
    generation, outages, constraints, weather, and fuels — covering real-time
    and 15+ years of history, with time-series and object endpoints intended for
    Excel, Python, R, and system integration. The service host is live and
    confirmed at https://services.yesenergy.com/PS/rest/, which returns HTTP 401
    with `WWW-Authenticate: Basic realm="Realm"` to anonymous callers; HTTP Basic
    credentials are issued only to paying subscribers. The endpoint reference and
    code examples live in the customer knowledge base at help.yesenergy.com,
    which 302-redirects to the services.yesenergy.com customer login, so no
    endpoint list, no scopes, and no machine-readable specification could be
    verified anonymously. Nothing beyond the base path and auth scheme is
    recorded here because nothing beyond that is publicly observable.
