BT Group

BT Group plc (British Telecommunications) is the United Kingdom's largest fixed-line, broadband, and mobile communications provider, headquartered in London with operations spanning consumer, business, wholesale, and global enterprise markets. The group is organised around three customer-facing brands — BT, EE, and Plusnet — and a wholesale division that sells capacity and access to other communications providers. BT Group operates the UK's largest mobile network (EE), runs fibre and copper access through Openreach (a legally separate group company), and provides networked IT and security services to multinational enterprises and the UK public sector. The group publishes a public developer programme at developer.bt.com that exposes a growing catalogue of REST APIs across two main domains: charging and crediting (Direct Carrier Billing, Crediting, Premium SMS) and digital identity / fraud prevention (SIM Swap, Network Identity, Call Divert Protection), alongside wholesale and operational APIs (Broadband One, Quote Management, Address Management, Appointment Management, Product and Network Availability, HubCo Voice, Global Voice Services, IMEI Lookup, Home Network, Rail Insights, Location Insights for London, and a Travel Journey API Platform). The portal supports sandbox onboarding with Client ID / Client Secret OAuth 2.0 credentials and progression to production under a commercial agreement with an account team. In April 2025 BT announced a federated API management partnership with Kong (Kong Konnect) to consolidate its previously fragmented API estate, strengthen governance, and offer a self-service developer experience across the group.

human only

Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.

Kin Score

API Evangelist profiles BT Group the way a machine reads it — 17 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 — BT Group scores 8.5/100 (minimal), with a separate agent-readiness read of 0/100 (human only). 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 BT Group

Each block below is one kind of artifact we hold for BT Group. 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.

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.

Where this information came from

This is an independent, third-party profile of BT Group, 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.
