École des Ponts ParisTech
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.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles École des Ponts ParisTech the way a machine reads it — 10 machine-readable artifacts across 4 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 — École des Ponts ParisTech scores 33.2/100 (thin), with a separate agent-readiness read of 6/100 (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.
Why this profile is thin
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.
This is an honest zero, not a gap in our research. École des Ponts ParisTech does not appear to expose an API, so there is nothing here for us to index and nothing for them to fix.

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 École des Ponts ParisTech
Each block below is one kind of artifact we hold for École des Ponts ParisTech. 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 4
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.

Pricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.
Published pricing tiers and plan structures.
Rate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.
Ecole Des Ponts Paristech Rate Limits
RATE LIMITSFinOps 1
Cost, billing, and metering signals let a buyer model the financial operations of an API before it's live. We profile them for the same reason we profile pricing: the money is part of the contract.
Cost, billing, and metering signals for API financial operations.
Semantic Vocabularies 1
JSON-LD contexts give the data shared meaning across APIs. We profile them because semantics are what let a machine reconcile 'customer' here with 'customer' somewhere else.
JSON-LD contexts and semantic vocabularies used across these APIs.
Security Posture 2
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 École des Ponts ParisTech, 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.
