Bayou Energy

Bayou Energy provides a utility-bill and usage-data API that lets companies collect their customers' utility account, bill, and interval meter data from US utilities. Customers link their utility credentials through a hosted onboarding flow, and Bayou continuously fetches the full bill and interval history, exposing it through a REST API secured with HTTP Basic authentication.

Bayou Energy publishes 4 APIs on the APIs.io network, including Bills API, Customers API, Intervals API, and 1 more. Tagged areas include Utility Data, Energy, Utility Bills, Interval Data, and Metering.

Bayou Energy’s developer surface includes authentication, documentation, engineering blog, and 7 more developer resources.
