method: probed
source: >-
  Live anonymous probe of https://services.yesenergy.com/PS/rest/ (HTTP 401 with
  a WWW-Authenticate challenge), plus /.well-known/ discovery probes on the same
  host. No OpenAPI security schemes exist to derive from — Yes Energy publishes
  no machine-readable specification.

  notes: >-
    Single auth mechanism. HTTP Basic over TLS 1.3, credentials issued only to
    contracted subscribers. No API-key header scheme, no OAuth 2.0, no OpenID
    Connect, and no mutual TLS is published or discoverable.

    curl -I https://services.yesenergy.com/PS/rest/ -> HTTP/2 401 with
    `www-authenticate: Basic realm="Realm"` (probed 2026-07-27); the same
    services.yesenergy.com/PS security realm fronts the PowerSignals web
    application login at /PS/security/login.
  credential_issuance: >-
    Commercial subscription only. There is no self-serve signup, no free tier,
    no API-key console, and no sandbox. The published entry paths are the demo
    request form (https://www.yesenergy.com/demo), support@yesenergy.com, and
    +1 303-993-2773. Credentials appear to be the customer's PowerSignals
    account username/password.
