ATCO
ATCO Ltd. (TSX: ACO.X) is a Calgary, Alberta diversified global corporation and the controlling shareholder of Canadian Utilities Limited, through which it runs the regulated energy businesses that make it one of western Canada's largest utility groups. It sits across several tiers of the value chain at once: ATCO Electric owns and operates electricity transmission and distribution across Alberta, ATCO Gas and ATCO Pipelines distribute and transmit natural gas in the province, ATCO EnPower builds storage, renewables and hydrogen assets, ATCO Australia operates gas distribution infrastructure in Western Australia, and ATCO Energy is a competitive retailer selling electricity, natural gas and home services to Alberta customers. Its API posture is the mirror image of the Ontario utilities: no consumer energy data mandate reaches it at all. Alberta has no Green Button regulation, ATCO is not on the Green Button Alliance member list, and it does not appear in the public Australian CDR energy data holder register — so there is no consumer data API, and a customer's usage and billing data lives only behind the My Account login on a Salesforce commerce portal. What ATCO does publish, unmandated and without any signup at all, is real open grid data: ATCO Electric's DER hosting capacity map is served from a public, anonymously queryable Esri ArcGIS REST feature service carrying 880,623 feeder segment features, linked directly from ATCO Electric's own micro-generation and grid-connection pages. Open grid data, closed consumer data, no developer portal, and no OpenAPI anywhere on the estate.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles ATCO the way a machine reads it — 9 machine-readable artifacts across 2 APIs, 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 — ATCO scores 28.4/100 (thin), with a separate agent-readiness read of 26/100 (agent aware). 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 ATCO
Each block below is one kind of artifact we hold for ATCO. 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 2
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.
ATCO Query API
Read-only queries against the hosting capacity feature layer
ATCO Service API
Feature service and feature layer metadata
Open Collections 3
Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.
Open, tool-agnostic API collections (OpenAPI-derived and Bruno).

OPEN COLLECTIONArazzo Workflows 1
Real integrations are rarely a single call. Arazzo describes the multi-step sequences — auth, then create, then confirm — so both a human and an agent can follow the choreography, not just the endpoints.

ARAZZOSecurity Posture 2
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
Recommended x-agentic-access execution contracts for AI agents.

This is an independent, third-party profile of ATCO, 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.
