UK Power Networks
UK Power Networks is the distribution network operator for London, the South East and the East of England, running three electricity distribution licence areas — London Power Networks (LPN), South Eastern Power Networks (SPN) and Eastern Power Networks (EPN) — and the Distribution System Operator function that sits on top of them. It is a poles-and-wires business: it owns the substations, cables and overhead lines, holds the network capacity and connection queue, and handles more than 70,000 connection enquiries a year, but it does not sell electricity and has no retail customer relationship to expose. Its API posture is the exact inverse of the usual utility story. Britain never legislated a consumer energy data right — there is no CDR equivalent, no Green Button obligation, and the one thing the UK did mandate was infrastructure (the Smart DCC carrying smart-meter traffic under the Smart Energy Code), which produces no public API. What did produce an API was Ofgem's Data Best Practice and digitalisation obligation on network licensees, and UK Power Networks has actually implemented it: a live Opendatasoft-hosted Open Data Portal serving 136 datasets over a documented, versioned REST API with a real OpenAPI 3.0.3 contract published at its own domain, a DCAT-AP catalogue export, and an official open-source Python client (ukpyn) on PyPI. So the split is unusually sharp and unusually positive on one side: market and network data is genuinely open and genuinely queryable — live faults, carbon intensity, embedded capacity register, substation and feeder-level smart meter aggregates, LTDS tables, flexibility dispatches, curtailment events — while consumer data is not merely closed but absent, because as a DNO it holds no billable customer account to hand over. The gate is free and self-serve rather than open: the catalogue and 36 of 136 datasets answer anonymously, but the other 99 return HTTP 403 until you register a free account and mint an API key.
Solid contracts, transparent operations, and an easy start — typically complete on four or five facets with one clear soft spot.
API Evangelist profiles UK Power Networks the way a machine reads it — 14 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 — UK Power Networks scores 66.0/100 (strong), with a separate agent-readiness read of 33/100 (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. 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 UK Power Networks
Each block below is one kind of artifact we hold for UK Power Networks. 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 2
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.
UK Power Networks Catalog API
API to enumerate datasets
UK Power Networks 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 COLLECTIONRate 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 LIMITSExamples 5
Real request and response payloads are what turn a spec from abstract into obvious — and they're one of the twelve things an agent needs to call an API correctly on the first try.
Example request and response payloads for these APIs.
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.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
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 UK Power Networks, 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.
