Green Button Connect My Data is the OAuth2-based ESPI service that lets Con Edison customers authorize a registered third party to receive their interval energy usage and account data on a recurring basis. Third parties register through Con Edison's onboarding process to obtain client credentials, then exchange them for access tokens that retrieve ESPI Atom/XML resources for usage points, meter readings, and electric power usage summaries.
Green Button Connect My Data is one of 2 APIs that Consolidated Edison publishes on the APIs.io network, described by a machine-readable OpenAPI specification.
Tagged areas include Energy, Green Button, Authentication, Smart Meter, and Usage Data. The published artifact set on APIs.io includes API documentation, authentication docs, an OpenAPI specification, an API reference, and a getting-started guide.

This is an independent, third-party profile of Green Button Connect My Data, published by
API Evangelist. We do not operate, host, resell, or

Everything here is built from publicly available information — the company's own site,
developer portal, documentation, public repositories, and the specifications it publishes for public use.
Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's
public API artifacts, scored against a published rubric. They are not certifications,
endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and
you do not need to justify the request. A removed company is recorded as unrated, never scored
zero for having asked. Acknowledgement within one business day; removal within two.
