Lunar Energy

Lunar Energy is a Mountain View, California-based residential clean-energy company founded in August 2020 by former Tesla Energy executive Kunal Girotra. The company designs and manufactures the Lunar System — a modular home battery (15–30 kWh, 9.6 kW continuous / 15 kW peak), Lunar Inverter, Lunar Maximizers (module-level power optimizers), Lunar Bridge meter socket adapter, and Eaton AbleEdge smart-breaker integration — controlled by the Lunar App with Lunar AI optimization. Its Gridshare platform is a grid-edge DERMS (Distributed Energy Resource Management System) and virtual power plant engine that manages 130,000+ residential distributed energy resources representing 1.2 GWh of connected storage across multiple manufacturers and third-party operators. Gridshare powers utility demand response and VPP programs through flex groups, flex dispatches, prognoses, dynamic and periodical tariffs, and per-device remote operation-mode control. Lunar Energy is backed by SunPower and Sunrun partnerships; SoftBank Energy is a major investor. The Gridshare Partner API and Customer API are gated behind business onboarding — credentials are issued by Lunar Energy after contacting [email protected].

agent ready

Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.

Kin Score

API Evangelist profiles Lunar Energy the way a machine reads it — 54 machine-readable artifacts across 14 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 — Lunar Energy scores 49.9/100 (developing), with a separate agent-readiness read of 48/100 (agent ready). 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.

How we profile Lunar Energy

Each block below is one kind of artifact we hold for Lunar Energy. 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 14

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.

Gridshare Remote MCP Server

Gridshare publishes a remote Model Context Protocol (MCP) server that exposes the Customer API as MCP tools for AI agents. Authenticated with the same Cognito-issued bearer toke...

Lunar Energy Devices API

List, get, and partially update customer devices

Lunar Energy Diff Requests API

Request and commit differential adjustments to a prognosis

Lunar Energy Dynamic Tariffs API

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.

Pricing Plans 1

Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the six things the Kin Score reads for commercial clarity.

Published pricing tiers and plan structures.

Rate 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.

FinOps 1

Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.

Semantic Vocabularies 1

JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.

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.

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.
