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.

NTT is listed with 6 APIs on the APIs.io network, including Communications Things Cloud, and 5 more. Tagged areas include Telecommunications, Mobile Network, Enterprise Cloud, Smart Data Platform, and IOWN.

NTT’s developer surface includes YouTube channel and 23 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Telecommunications regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
Machine-Readable Auth +10 pts — a served openid-configuration/oauth-authorization-server carrying `issuer` (served), else the securitySchemes class in the provider OpenAPIs — bound (mutualTLS, DPoP, Signature) > negotiable (oauth2 authorizationCode/clientCredentials, openIdConnect) > bearer (http bearer, apiKey)
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0

12 more unmet checks in the Agent Readiness table above.

Contract Quality scores 24.0 — up to +19.0 composite points
Developer Ergonomics scores 33.3 — up to +13.3 composite points

Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it.

Markets this provider is in provisional

The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.

Market	Position	Depth	Registered MCP server	Declares compatibility
Network Edge (CDN, networking, peering, edge compute)	regulated	43.5 (thin)	-	-
Infrastructure-as-Code Provider Registries (Terraform, OpenTofu, Pulumi)	regulated	43.5 (thin)	-	-
Japan ISMAP Cloud Security Assessments (TISAX unreadable)	regulated	43.5 (thin)	-	-

Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

Standards implemented 1

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
