Nanyang Technological University (NTU Singapore) is an autonomous public research university in Singapore, ranked in the top 15 of the QS World University Rankings. Its programmable footprint is small, indirect, and almost entirely research-infrastructure: NTU operates no public developer portal, publishes no API key self-service, and exposes no OAuth or OIDC authorization server on any host it owns. Exactly one machine-readable API is genuinely NTU-operated — DR-NTU (Data), a Dataverse 6.1 open research data repository that NTU self-hosts on its own network (researchdata.ntu.edu.sg CNAMEs to dataverse.ntu.edu.sg at 155.69.19.238, registered to Nanyang Technological University), backed by NTU's own DataCite client GDCC.NTU with 3,625 DOIs under prefix 10.21979. Everything else that carries NTU's name is a tenancy on someone else's platform. DR-NTU (Digital Repository), the far larger surface with 158,100 research profiles, a DSpace 7 REST API and a fully conformant OAI-PMH endpoint, answers on dr.ntu.edu.sg but CNAMEs to ntu-cris.4science.cloud — NTU's data and NTU's library administration running on 4Science's DSpace-CRIS platform. NTU's federated single sign-on is a live SAML 2.0 identity provider in eduGAIN, but the entityID and endpoints sit on SingAREN's SGAF proxy, not on ntu.edu.sg. NTU owns a live API gateway at api.ntu.edu.sg which returns a structured JSON 404 on every path and documents no route at all. This profile records the tenancies as the real institutional facts they are, and credits NTU only for what NTU actually operates.
Nanyang Technological University publishes 8 API contracts indexed on the APIs.io network, including DR-NTU (Data) — Dataverse API, Discover API, Items API, and 5 more. Tagged areas include University, Higher Education, Education, Singapore, and Public Research University.
The Nanyang Technological University catalog on APIs.io includes 1 JSON-LD context and 2 Spectral governance rulesets.
Nanyang Technological University’s developer surface includes engineering blog, documentation, support, and 25 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Education & Research 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 does not apply to this provider. The published contracts declare
no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's
denominator entirely — not scored zero. A reference or data API is not deficient for being unable to
upsert.
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
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)
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
Delegated User Identity+6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
6 more unmet checks in the Agent Readiness table above.

x-coverage:
state: unreadable
reason: 'The single institution-operated API in this profile is behind an edge bot-management gate that returns 403 to every
automated client, so its contract could not be re-read on this run. The profile is otherwise thin because NTU genuinely
publishes very little: no developer portal, no API documentation of its own, and no institution-operated API beyond its
research data repository.'
detail: 'researchdata.ntu.edu.sg (DR-NTU (Data), the one x-operator: institution surface) returns an Apache 403 with a Citrix
bot-management cookie and a /trap.html honeypot link on EVERY path, including the site root and robots.txt. Retrying with
a browser User-Agent and a persisted cookie jar did not clear it. This is a block on us, not a decommissioned service:
NTU''s DataCite client minted a DOI on 2026-08-17, two days before this profile, and re3data independently lists the REST,
OAI-PMH and SWORD endpoints as current. The archived contract in openapi/_original/ntu-drntu-data.yaml is therefore retained
and the two refined specs kept, but marked unverified in authentication/ and errors/. A re-probe from a different vantage
should upgrade this to covered. Every other surface WAS read live: dr.ntu.edu.sg answered 200 on /server/api and on OAI-PMH
Identify and ListMetadataFormats, the SGAF SAML metadata returned 200 application/samlmetadata+xml, and eduGAIN, DataCite
and re3data all answered. Four of the six OpenAPIs previously in this repo were removed: refine-openapis had merged three
source specs spanning two different hosts by tag and stamped all six with the first spec''s server, so the DSpace paths
(/, /core/items/{uuid}, /discover/search/objects) and the OAI-PMH /request path were all asserting researchdata.ntu.edu.sg
as their host, which never served them.'
