NTT
NTT (Nippon Telegraph and Telephone Corporation) is a Tokyo-headquartered global technology and telecommunications group with roughly 340,000 employees and a 150-year history of innovation. The group operates through five business divisions — Consulting & IT Services, Mobile Solutions, Smart Tech, Consumer & Business, and Research & Development — and is anchored by major subsidiaries including NTT DOCOMO (Japan's largest mobile carrier), NTT Communications / NTT DOCOMO BUSINESS (enterprise cloud, network, and platform services), NTT DATA Group (global IT services and systems integration), NTT Ltd. (managed services), and NTT Research. NTT exposes a substantial developer surface through the NTT DOCOMO BUSINESS Developer Portal at developer.ntt.com, which catalogs enterprise APIs across Network (Arcstar Universal One, Flexible InterConnect, Global M2M), Cloud (Smart Data Platform, Enterprise Cloud 2.0), Voice, App (Safety Confirmation, Text & Language Analysis, Speech Recognition), Management (asset visibility, vulnerability), and Core (Authorization, Billing, API Log, Business Process, Service Order, Pay-per-use, Price, Organization, Personal Profile) categories. The group also publishes IoT APIs (Things Cloud) and a docomo Developer support portal at dev.smt.docomo.ne.jp. NTT's primary open source presence is the nttcom GitHub organization, which ships the Enterprise Cloud Python and Go SDKs (eclsdk / eclcloud), the eclcli command-line tool, Terraform providers for Enterprise Cloud 2.0 (terraform-provider- ecl) and Flexible InterConnect (terraform-provider-fic), the ksot network-IaC framework, the pola stateful PCE / PCEP library, the fluvia eBPF/XDP IPFIX exporter, and threatconnectome for SBOM-driven vulnerability management. NTT DATA additionally maintains regional GitHub orgs (NTTDATA, NTTDATA-EMEA, NTTDATA-DACH, NTTDATAInnovation, launchbynttdata, nttdata-oss) covering testing automation, Kubernetes plugins, and LLM observability tooling. NTT also drives the IOWN (Innovative Optical and Wireless Network) initiative, photonics and optical-quantum research, and responsible AI development across its R&D arm.
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 NTT the way a machine reads it — 7 machine-readable artifacts across 6 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 — NTT scores 17.0/100 (emerging), with a separate agent-readiness read of 13/100 (agent aware). 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 NTT
Each block below is one kind of artifact we hold for NTT. 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 6
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.

Security Posture 1
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.

This is an independent, third-party profile of NTT, 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.
