Accenta

Accenta is a French energy and carbon performance company for real estate portfolios, founded in 2016 and headquartered in Boulogne-Billancourt. It combines AI-driven building control (an intelligent building management system plus an Accenta Communication Box for sites with no BMS) with low-carbon heat and cold production built on shallow geothermal energy, inter-seasonal geostorage, heat pumps and solar, and it wraps the whole package in audit, design, build, operate, financing and performance-contract services. Accenta says it manages roughly 10 million square metres of real estate for owners such as Airbus, Prologis, Icade, Redevco and Decathlon, targeting energy reductions up to 80% and CO2 reductions up to 95%. Its software platform is effiPilot, acquired in 2020, delivered as a per-customer tenant on accenta.ai with a web application, an Android app and an HTTP API whose reference documentation sits behind the customer login.

Accenta is listed with 1 API on the APIs.io network. Tagged areas include Company, Ai Data, Energy, Buildings, and Smart Buildings.

Accenta’s developer surface includes support, engineering blog, authentication, and 22 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Energy & Utilities regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/accenta: open an issue to ask a question, or submit a pull request to add artifacts.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

  description: 'The HTTP API behind Accenta''s effiPilot building-energy platform. It is an RPC-style JSON surface — requests
    take the form /api/method/<methodName> — served per customer tenant from the wildcard accenta.ai host (nginx + PHP 8.0.30),
    with session-cookie authentication established through the platform login. The API reference is published by Accenta as
    "documentation API effiPilot" at /api/doc on the tenant host, but that route is only routed for an authenticated session;
    anonymous requests return {"message":"Route not found"}. One anonymous method is reachable and was verified: /api/method/brandConf,
    which returns the tenant brand, legal-entity, consent and colour configuration as JSON. No OpenAPI, Swagger, GraphQL or
    MCP contract is published on any Accenta host.'

  detail: Accenta's effiPilot API reference is real and is Accenta's own — the login application at app.accenta.ai explicitly
    offers redirectTo=api%2Fdoc and search engines still index the page title "documentation API effiPilot 2.16.3" — but the
    /api/doc route is only served to an authenticated tenant session, so an anonymous GET returns {"message":"Route not found"}
    and no machine-readable contract of any kind (OpenAPI, GraphQL, MCP, AsyncAPI, agent card, or any /.well-known/ document)
    is reachable on www.accenta.ai, app.accenta.ai or demo.accenta.ai.
