Landis+Gyr
Landis+Gyr Group AG is a 130-year-old energy technology company that builds the smart electricity, gas and water meters, the RF-mesh and cellular networks, and the head-end, meter-data-management and grid-analytics software that utilities run advanced metering infrastructure on. It is incorporated in Cham, Switzerland and listed on the SIX Swiss Exchange, but after divesting its EMEA business to AURELIUS in March 2026 its centre of gravity — and its Americas headquarters and much of its executive team — sits in Alpharetta, Georgia, making the United States its home market. Landis+Gyr sits one layer UPSTREAM of the consumer: it sells to the roughly 2,000 utilities that are themselves the regulated data holders, so no data-sharing mandate — not US Green Button, not Ontario's Green Button regulation, not Australia's Consumer Data Right for energy — attaches to Landis+Gyr itself. Its API posture reflects that. Landis+Gyr publishes NO open market or grid data and NO consumer usage API; the meter interval data its Gridstream Connect and MDMS products produce reaches households only after a utility customer re-publishes it, typically through a third-party Green Button–certified portal that Landis+Gyr does not operate. There is a real developer portal at developers.landisgyr.com — the Gridstream Connect Apps / Revelo edge-app program, with App Studio, documents, learning paths, a Stack Overflow Teams developer forum and a Revelo developer-kit request flow — but every content route renders empty without authentication, the registration path carries an admin invitation and approval workflow, and the corporate site never links to it: the public call to action on the Apps Ecosystem page is "Email Our Team", pointing at a sales inquiry form. No OpenAPI, Swagger, Postman collection, SDK download or endpoint reference is published anywhere in public. The only interoperability standard Landis+Gyr states publicly is Wi-SUN FAN certification (15 certified products) over standards-based IPv6 mesh — a network standard, not a customer-data standard.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
API Evangelist profiles Landis+Gyr the way a machine reads it — 3 machine-readable artifacts, 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 — Landis+Gyr scores 26.1/100 (emerging), with a separate agent-readiness read of 0/100 (human only). 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 Landis+Gyr
Each block below is one kind of artifact we hold for Landis+Gyr. 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.
Security 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.

This is an independent, third-party profile of Landis+Gyr, 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.
