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.
More than an index entry, but the surface is still mostly links rather than artifacts — the cohort most likely to move a full band from modest, well-targeted work.
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 18.0/100 (emerging), 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.

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.
