EnergyHub Mercury Edge Connect API is one of 2 APIs that [EnergyHub](https://apis.io/providers/energyhub/) publishes on the [APIs.io](https://apis.io/) network. Tagged areas include DERMS, OpenADR, Demand Response, Distributed Energy Resources, and Partner. The published artifact set on APIs.io includes API documentation.

Mercury Edge Connect is EnergyHub's standardized integration framework for connecting DER providers (thermostat, battery, EV, EV charger, and solar inverter manufacturers) to the Mercury/Edge DERMS platform. EnergyHub states in its 2021-02-18 announcement that "At the heart of Mercury Edge Connect is a new API designed specifically to meet the requirements of managing behind-the-meter DERs at scale. The API is based on the Open ADR standard, with enhanced functionality around automated enrollment, monitoring, and other functionality required for managing enterprise-wide portfolios of grid-edge and customer-owned DERs." No public reference documentation, schema, or operation list is published. The host mec.energyhub.com (the name matches Mercury Edge Connect; that mapping is inferred, not stated by EnergyHub) was probed on 2026-07-27 and is live behind a valid DigiCert RapidSSL certificate for CN=mec.energyhub.com, returning HTTP 400 "No required SSL certificate was sent" to every anonymous request on /, /openapi.json, /swagger.json, /docs, /api-docs, /.well-known/openid-configuration, /health, /v1, /api, and /oadr, which is mutual TLS client-certificate authentication consistent with the OpenADR 2.0b VEN/VTN security model. Access requires a DER partner agreement.
