Arcadia

Arcadia is a clean-energy access and energy-intelligence company that operates Arc, a utility data platform giving developers programmatic access to utility bills, statements, meters, interval (15-minute) usage data, tariff rates, and provider metadata across thousands of US and international utilities. Arc combines the Plug API for utility data, Arcadia Connect for hosted credential collection and MFA, Signal for tariff and rate calculations, and webhooks for asynchronous events. Arcadia powers solar and storage modeling, EV charging, energy management, property management, and carbon accounting for customers including Ford, EVgo, Enphase, Oracle, UPS, Conagra, Penske, and ~25% of the Fortune 500. In April 2026 Arcadia acquired ENGIE Impact, adding utility bill management, energy procurement advisory, and sustainability reporting capabilities.

agent ready

Solid contracts, transparent operations, and an easy start — typically complete on four or five facets with one clear soft spot.

Kin Score

API Evangelist profiles Arcadia the way a machine reads it — 46 machine-readable artifacts across 15 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 — Arcadia scores 63.3/100 (strong), 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 Arcadia

Each block below is one kind of artifact we hold for Arcadia. 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 15

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.

Arcadia Connect API

Arcadia Connect is a hosted credential-collection web experience that handles utility account onboarding — credential capture, MFA flows, one-time passcodes, and credential refr...

Arcadia Signal API

Arcadia Signal provides utility tariff and energy rate data and calculations for use in cost-benefit analyses, bill audits, project forecasting, and financial modeling. Signal p...

Arcadia Webhooks API

List, retrieve, and resend webhooks for asynchronous Plug platform events including statement availability, meter activation, interval data readiness, and credential lifecycle c...

Arcadia Utility Cloud API (Legacy)

The legacy Utility Cloud REST API — predecessor to the Plug API — still documented for existing integrations. New integrations should use the Plug API; the Utility Cloud version...

Arcadia Accounts API

Utility accounts discovered for a credential.

Arcadia Credentials API

Utility-login credentials used to pull data on behalf of customers.

Arcadia Files API

Source documents (PDFs, etc.) for statements and other artifacts.

Arcadia Intervals API

Time-series consumption data, typically 15-minute resolution.

Arcadia Meters API

Individual measurement devices associated with accounts and sites.

Arcadia OAuth API

Access token issuance.

Arcadia Organizations API

Top-level organization resource.

Arcadia Providers API

Utility providers supported by the platform.

Arcadia Sites API

Physical service locations grouping meters and accounts.

Arcadia Statements API

Utility bills / statements pulled from the provider.

Arcadia Webhooks API

Asynchronous events for statement, meter, and credential lifecycle.

Open Collections 1

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 COLLECTION

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.

Governance rulesets we run against this provider's specs — the automated checks behind parts of the score. Profiling them makes the quality bar explicit and re-runnable, not a matter of opinion.

JSON Schema 3

Standalone JSON Schema definitions describe the data models behind the API. We profile them so the shapes are validatable on their own — useful long after a single request is forgotten.

Security Posture 4

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.
