ERCOT
The Electric Reliability Council of Texas (ERCOT) is the independent system operator that manages the flow of electric power to roughly 27 million Texas customers on the ERCOT Interconnection, running the wholesale Day-Ahead and Real-Time energy markets, ancillary services, congestion revenue rights, and retail switching for the competitive Texas market. Its home market is the United States (Texas). ERCOT sits at the wholesale/system-operator layer of the energy value chain, upstream of the transmission and distribution utilities (Oncor, CenterPoint, AEP Texas, TNMP) and the retail electric providers that serve end customers. Its API posture is a clean split: market and grid data are genuinely open — ERCOT publishes a real, versioned OpenAPI 3.0 for the Public Data API covering 106 EMIL data-product endpoints (locational marginal prices, settlement point prices, system load, wind and solar production, ancillary services, outage capacity), and the Market Information System still serves public report archives anonymously with no account at all. Consumer energy data is a different story: ERCOT operates no consumer usage API and implements no Green Button / ESPI surface. Texas residential interval data lives in Smart Meter Texas, which is operated by the joint Transmission and Distribution Utilities under PUCT oversight, not by ERCOT. The market-participant SOAP estate (ERCOT Web Services, MarkeTrak, Retail API) is documented publicly on GitHub but reachable only by certified market participants.
Solid contracts, transparent operations, and an easy start — typically complete on four or five facets with one clear soft spot.
API Evangelist profiles ERCOT the way a machine reads it — 47 machine-readable artifacts across 1 API, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
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. From those artifacts we compute the Kin Score — ERCOT scores 54.6/100 (strong), with a separate agent-readiness read of 40/100 (agent native). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile ERCOT
Each block below is one kind of artifact we hold for ERCOT. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 41
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.

Not every API is request/response. AsyncAPI describes the event-driven and streaming side — the webhooks and channels — so the asynchronous half of the interface is documented the same way the synchronous half is.

This is an independent, third-party profile of ERCOT, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. 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.
