Hydro-Québec
Hydro-Québec is the government-owned Crown corporation that generates, transmits and distributes almost all of the electricity consumed in Québec, Canada — a vertically integrated, near-monopoly utility running one of the largest hydroelectric fleets in the world and serving roughly 4.6 million customer accounts across the province. It sits at every point of the value chain at once, as generator, transmission owner, distributor and retailer, plus a cross-border exporter into the New England and New York markets. Its API posture is a clean split. Market and grid data is genuinely open — a public Opendatasoft-powered portal at donnees.hydroquebec.com serves 26 datasets (electricity demand and generation, imports and exports, outages, GHG emission factors, hydrometric and weather data, winter peak demand events, vegetation control) through a documented, anonymously callable REST API with a machine-readable OpenAPI 3.0.3 description and a DCAT catalog export, licensed CC BY-NC 4.0. Consumer data is closed — there is no documented customer-facing API, no Green Button Download My Data or Connect My Data service, and no third-party consent flow; a customer's own usage is reachable only by logging into the Espace client web portal. Québec has no consumer energy data right. Ontario's Green Button regulation (O. Reg. 633/21 under the Electricity Act, 1998) is province-specific and does not bind Hydro-Québec, and Canada has no national equivalent to Australia's Consumer Data Right energy regime. Open market data, closed consumer data, no mandate.
Solid contracts, transparent operations, and an easy start — typically complete on four or five facets with one clear soft spot.
API Evangelist profiles Hydro-Québec the way a machine reads it — 12 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 — Hydro-Québec scores 56.9/100 (strong), with a separate agent-readiness read of 43/100 (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 Hydro-Québec
Each block below is one kind of artifact we hold for Hydro-Québec. 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 3
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.
Hydro-Québec Open Data Search API v1
The legacy Opendatasoft Search API v1 still served on the Hydro-Québec open data portal. Verified live and anonymous on 2026-07-27 — GET /api/datasets/1.0/search/ returned HTTP ...
Hydro-Québec Catalog API
API to enumerate datasets
Hydro-Québec Dataset API
API to work on records
Open Collections 2
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 COLLECTIONMCP Servers 1
Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

MCP SERVERRate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.

RATE LIMITSSecurity Posture 3
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.
Scopes 1
OAuth scopes are the vocabulary of least-privilege access. Profiling them shows exactly what an integration — or an agent acting on a user's behalf — is allowed to do.
OAuth scopes governing access to this provider's APIs.
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 Hydro-Québec, 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.
