Cms Energy Plans Pricing
CMS Energy publishes NO API price list, and that is the finding rather than a gap in the search. Both public API surfaces are free at the point of use, for different reasons: the Consumers Energy ArcGIS outage services are anonymous public geodata with no account of any kind, and the Green Button Connect My Data program is described by Consumers Energy as "provided as a courtesy to Consumers Energy customers". Access to GBCMD is gated by registration and utility review, not by payment.
Cms Energy Plans Pricing is the machine-readable pricing-plan profile for CMS Energy on the APIs.io network, conforming to the API Commons Plans specification.
It defines 2 plans, covering free tiers, with named plans including Consumers Energy public outage services, Green Button Connect My Data — third party.
Tagged areas include Electric, Energy, Natural Gas, Utility, and Green Button.

- Sandbox test scenarios before live approval
- Opt-in webhooks
