Elium is a European enterprise knowledge-management SaaS platform, founded in 2007 as Knowledge Plaza and renamed Elium in 2017, headquartered in Louvain-la-Neuve, Belgium. Teams capture, validate and govern company knowledge as structured articles - which Elium calls "stories" - inside spaces, using templates, multi-step approval, expiration management, duplicate and gap detection, and in-place multilingual translation. The same governed corpus is then served to people and to AI agents through AI search, smart assistants, external portals and integrations. Programmatically Elium is a GraphQL provider, not a REST one: each customer platform serves its own per-tenant GraphQL endpoint with 17 queries, 206 mutations and 18 subscriptions, documented in a fully published SpectaQL reference, secured with OAuth 2.0 on a single apiv1 scope. In June 2026 Elium added a per-tenant remote Model Context Protocol server exposing three read-only knowledge tools to ChatGPT, Claude and custom agents. API and MCP access are Enterprise-plan only. Elium is ISO/IEC 27001:2022 certified and SecNumCloud-qualified, with EU-default and sovereign French hosting options.
Elium publishes 2 APIs on the APIs.io network. Tagged areas include Company, Software-as-a-Service, Knowledge-Management, Knowledge Base, and Enterprise Search.
The Elium catalog on APIs.io includes 1 event-driven AsyncAPI specification.
Elium’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 26 more developer resources.
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.
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. This rating is computed from github.com/api-evangelist/elium: open an issue to ask a question, or submit a pull request to add artifacts.

description: Elium's single GraphQL endpoint, served per tenant at https://{platform}.elium.com/graphql. 17 queries, 206
mutations and 18 subscriptions over 1128 type definitions, covering stories (content), spaces, users, templates/schemas,
tags, comments, annotations, alerts, smart assistants and tenant administration. OAuth 2.0 bearer with one scope, apiv1.
Relay cursor connections for pagination; errors are returned in-band on each mutation payload rather than as HTTP status
codes. No OpenAPI is published - GraphQL is the contract. Enterprise plan only.

x-api-base:
verdict: templated-by-design
repair_tool_verdict: no-usable-base
note: 'repair-api-bases.py reports "no-usable-base" because BOTH bases template the HOST, not just a path segment. That
verdict is correct about the shape and wrong about the cause: Elium has no shared API host to record. It deploys one platform
per subdomain and its own documentation uses placeholder tenant names throughout - my-platform.elium.com in the quick
start, mycompany.elium.com in the token example, your-platform-name.elium.com in the MCP article. api.elium.com resolves
but serves an application 404 on every path, including every spec path probed, so it is not the base either. Leaving {platform}
in place is the accurate record; substituting any concrete tenant would invent a customer''s hostname. Do not "repair"
this in a later round.'

x-pointers-deliberately-absent:
note: Recorded so a later round does not re-litigate these, and does not add a pointer the provider has not earned. Each
was probed or searched in this pass.
OpenAPI: None exists. Probed api.elium.com/openapi.json, /openapi.yaml, /swagger.json, /v1/openapi.json, /api-docs, /docs,
/redoc plus the docs host - all 404. GraphQL is this provider's contract.
AgentCard: /.well-known/agent-card.json and legacy /.well-known/agent.json probed on elium.com, api.elium.com, learn.elium.com
and help.elium.com - 404 everywhere except learn.elium.com, which answers 200 with an HTML docs shell for every /.well-known/*
path. No card, so per the pipeline contract no a2a/ artifact was authored.
WellKnown: Elium serves no /.well-known/ document of its own. The probe is recorded in well-known/elium-well-known.yml with
every status; no pointer, because a file documenting an absence must not be scored as a presence.
SecurityTxt: Absent on elium.com and api.elium.com. The 200 text/plain security.txt on help.elium.com is INTERCOM's (Canonical
app.intercom.com, contacts bugcrowd.com/intercom) because the help centre is Intercom-hosted.
Idempotency: Elium has no idempotency mechanism. Searched all 206 mutations, 244 input types and the API guides for /idempoten/i
- zero matches. Retrying storyPost creates a second story.
SDKs: No client library in any language on npm, PyPI, RubyGems, Packagist, crates.io, pkg.go.dev, Maven or NuGet. The four
first-party @eliumhq npm packages are internal build tooling, newest release 2020-01-15.
Webhooks: No outbound webhooks are advertised. The event surface is 18 GraphQL subscriptions, recorded in asyncapi/elium-events.yml
without an AsyncAPI or Webhooks pointer.
AsyncAPI: No AsyncAPI document is published.
Deprecation: Five operations carry a Deprecated marker in the reference, but there is no deprecation policy page, no notice
period and no RFC 8594 Sunset support to point at.
GitHubOrganization: github.com/elium and github.com/Elium belong to Molecule Science (molecule-science.com), a different
company. Elium's own code is on GitLab at gitlab.com/elium/product, which returns 403 anonymously.
Postman: www.postman.com/eliumhq returns only the Postman SPA shell - no public workspace or collection.
Roadmap: elium.com/roadmap returns 404.
CLI: No first-party CLI is published.
Sandbox: No sandbox, test mode, or test-vs-live key separation is published. There is a free trial of the product but no
developer test environment.
