École des Ponts ParisTech (École nationale des ponts et chaussées, ENPC) is a public French grande école of engineering founded in 1747, based in Champs-sur-Marne and a founding member of ParisTech. Its programmable footprint is small and must be read honestly: ENPC operates no public API programme, no developer portal and no API key issuance — api.enpc.fr and api.ecoledesponts.fr do not resolve, and there is no developer section anywhere in the 1,910-URL sitemap of ecoledesponts.fr. The single machine-readable contract ENPC genuinely operates itself is its SAML 2.0 Identity Provider metadata at idp.enpc.fr, whose entityID is registered in the RENATER Fédération Éducation-Recherche and therefore reachable through eduGAIN. Everything else that looks like an ENPC API is a tenant relationship on someone else's platform: the open-access repository is the ENPC collection inside the national HAL platform operated by CCSD; the research-data repository is the ecoledesponts collection inside the national Recherche Data Gouv Dataverse; and the heritage digital library, though served under heritage.ecoledesponts.fr, is a Gallica Marque Blanche deployment hosted on BnF infrastructure with BnF ARKs and BnF attribution. Those are real institutional facts and are recorded as tenant surfaces — the data is ENPC's, the contract is not.
École des Ponts ParisTech publishes 4 APIs on the APIs.io network. Tagged areas include University, Higher Education, Education, Technical University, and Grande École.
The École des Ponts ParisTech catalog on APIs.io includes 1 JSON-LD context.
École des Ponts ParisTech’s developer surface includes documentation, engineering blog, YouTube channel, authentication, and 20 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 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/.

detail: 'ENPC publishes no public API, no developer portal and no OpenAPI. Probed and found absent: api.enpc.fr, api.ecoledesponts.fr,
data.enpc.fr, data.ecoledesponts.fr (all DNS-unresolvable), /llms.txt and /.well-known/security.txt on the main site (404).
One institution-operated machine-readable contract exists and is recorded — the SAML 2.0 IdP metadata at idp.enpc.fr.
Every other programmable surface belongs to a national or vendor platform on which ENPC is a tenant: HAL (CCSD), Recherche
Data Gouv (Dataverse), and Gallica Marque Blanche (BnF), the last of which runs under an ENPC hostname that resolves into
BnF address space. The previous profile recorded the generic national HAL endpoints at api.archives-ouvertes.fr as ENPC''s
own APIs; they are shared national infrastructure used by every French institution and have been re-labelled as a single
tenant relationship. Two soft-200 traps were found and are NOT recorded as surfaces: the heritage SRU route returns the
HTML search page for every request including operation=explain, and idp.enpc.fr answers every unknown path, including
/.well-known/openid-configuration, with the LemonLDAP::NG portal shell. The HAL portal enpc.hal.science answers 200 with
an Anubis bot challenge — live, not dead. A dead pointer was removed: the previous Library pointer lib.enpc.fr now redirects
off-domain to an unrelated research demo at aikon-demo.huma-num.fr, and the previous Twitter pointer 404s with no X account
linked from the ENPC homepage.'

description: The one machine-readable contract École des Ponts ParisTech operates on its own infrastructure. A live SAML
2.0 EntityDescriptor served as application/xml from idp.enpc.fr, declaring SingleSignOnService over HTTP-Redirect, HTTP-POST
and HTTP-Artifact, SingleLogoutService over SOAP, HTTP-Redirect and HTTP-POST, an ArtifactResolutionService and an AttributeAuthorityDescriptor.
OrganizationName reads "École des Ponts ParisTech" and OrganizationURL https://www.enpc.fr. The entityID https://idp.enpc.fr/saml/metadata
appears in the RENATER Fédération Éducation-Recherche main IdP aggregate, so federation membership is confirmed from the
federation's own metadata rather than from an institutional claim. Software is LemonLDAP::NG, not Shibboleth. This authenticates
people into federated services; it is not a developer-accessible API.
