char.gy

char.gy is a British public electric-vehicle charge point operator that specialises in on-street charging for the roughly forty percent of UK households with no off-street parking, and it is best known for putting the charger inside the lamp post. Founded by Richard Stobart out of the digital agency Unboxed, it installed its first public charger in Marlow, Buckinghamshire in 2018, is now led by CEO John Lewis from Floor 5, 55 King William St, London EC4R 9AD, and is backed with £100m by Zouk Capital through the UK Government-backed Charging Infrastructure Investment Fund. Its own about page claims over 5,000 charge points and 28.3 million kg of CO2 saved, and its live open data feed returned an x-total-count of 5,409 locations on 2026-07-27. In the UK energy value chain it sits at the very end of the wire: it is not a licensed supplier, not a network operator and not a metering agent, it operates charge points on street furniture owned by local authorities — Haringey, Southwark, Brent, Barnet, Harrow, Coventry, Brighton and Hove, Richmond and Wandsworth, Enfield and others — authorising drivers, metering the session and pricing it. Britain has no consumer data-portability mandate for energy equivalent to Australia's Consumer Data Right, so nothing compels char.gy to expose an individual driver's usage or billing data through an API, and it does not: there is no consumer API, no OAuth server, no OpenID Connect discovery document and no accredited-recipient scheme anywhere on the domain. What Britain DID mandate here is open infrastructure data. The Public Charge Point Regulations 2023 (SI 2023/1168), Part 4 regulation 10(5), require every charge point operator to make reference data and availability data available to the public free of charge, in a machine readable format, and — the crucial clause — "without any requirement to agree to terms and conditions regarding the use of that data". char.gy complies, and the compliance is real rather than claimed: it publishes an OCPI-shaped Locations feed and an OCPI-shaped Tariffs feed at https://char.gy/open-ocpi/locations and https://char.gy/open-ocpi/tariffs, both of which returned HTTP 200 with application/json to a completely anonymous GET on 2026-07-27, paginated with x-total-count, x-limit and RFC 5988 Link rel="next" headers, carrying real GB*CGY*E*NNNNN EVSE identifiers, IEC 62196 Type 2 connectors, per-connector tariff_ids and time-of-day restricted pence-per-kWh price components. The posture is therefore the clean split this sector keeps producing, but rotated: market and infrastructure data wide open and genuinely ungated because a regulation forbids gating it, consumer data entirely absent because no regulation asks for it, and the commercial OCPI CPO roaming interface at /ocpi/cpo/ closed behind OCPI Token authorization for partner e-mobility service providers. There is no developer portal — the entire public documentation for the open API is a single Freshdesk help-centre article.

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 char.gy

Each block below is one kind of artifact we hold for char.gy. 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 3

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.

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.

Security Posture 2

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.
