NAESB
The North American Energy Standards Board (NAESB) is the non-profit, industry-consensus standards development organization formed in 1994 that writes the business practice standards for the North American wholesale and retail natural gas and electricity markets, organized into four quadrants — Wholesale Electric (WEQ), Retail Electric (REQ), Wholesale Gas (WGQ) and Retail Gas (RGQ). Headquartered in Houston, Texas, its home market is the United States (with Canadian and Mexican participation). NAESB sits upstream of every utility, ISO/RTO and energy-data platform in the value chain: it authors REQ.21 Energy Services Provider Interface (ESPI), the standard that is the basis of every Green Button implementation in North America, and it operates the NAESB Electric Industry Registry (EIR) that underpins electronic tagging across the wholesale electric market. Its API posture is deliberately split and must not be overstated. NAESB is not a data holder and no consumer-data mandate applies to it; the Green Button standard it publishes is adopted by US utilities purely voluntarily, with no federal obligation behind it. The specifications themselves are copyright-protected and paywalled — $8,000/year membership, $2,000 per quadrant version, or $250 per individual standard — with only a free, view-only, three-business-day evaluation waiver for non-members. The single genuinely open artifact is the set of ESPI XML schemas, released under Apache 2.0 as a documented one-time exception to the NAESB Copyright Policy and downloadable anonymously after a one-click terms-of-use acknowledgement. The one real API NAESB operates, the EIR webRegistry SOAP service administered by OATI, is closed: it requires a paid registry subscription and a digitally signed X.509 certificate issued by an NAESB-Authorized Certification Authority, and its endpoint could not even complete a TLS handshake anonymously. Open standard schemas, closed standards text, closed registry API, no consumer data and no open market data of its own.
NAESB is tracked in the API Evangelist network. This page is the human-readable profile that sits on top of the machine-readable index we maintain at apis.io.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
NAESB is in the network as a tracked entity. We haven't yet indexed a public API surface for it — when one is published, the artifacts, score, and agent-readiness read will appear here automatically. The source repository is where that profile is built.
