CrossEngage

CrossEngage is a Berlin-based customer data and cross-channel marketing platform (a Customer Data Platform / CDP) founded in 2015 and backed by Earlybird Venture Capital. It unifies first-party customer data into 360-degree profiles, builds no-code predictive AI/ML models for customer lifetime value and behavior, manages audiences with drag-and-drop segmentation, and orchestrates real-time cross-channel customer journeys across email, push, SMS, WhatsApp and webhooks. Following its acquisition by Spotler, the product is sold as Spotler Activate Pro. CrossEngage exposes six REST APIs on api.crossengage.io — User Management v1 and v2, Product Feed, Raw Export, Statistics and File Attachments — totalling 37 operations. Five are published as API Blueprint documents and one (Product Feed) as Swagger 2.0, all served from Apiary and embedded in the reference site at api.documentation.crossengage.io. Authentication is a static X-XNG-AuthToken header paired with a required X-XNG-ApiVersion header; there is no OAuth surface. Product documentation is published at documentation.crossengage.io, which serves a first-party llms.txt index of all 219 pages.

CrossEngage publishes 13 API contracts indexed on the APIs.io network, including Event management API, Lead management API, Opt-out management API, and 10 more. Tagged areas include Company, Customer Data Platform, Marketing, Customer Engagement, and Marketing Automation.

The CrossEngage catalog on APIs.io includes 1 event-driven AsyncAPI specification and 1 Spectral governance ruleset.

CrossEngage’s developer surface includes authentication, documentation, API reference, pricing, engineering blog, support, getting-started guide, and 34 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) 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 applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% 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
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)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
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.

Kin Score — facets with the most composite points still available (weight × headroom):

Contract Quality scores 48.4 — up to +12.9 composite points
Operational Transparency scores 36.8 — up to +8.2 composite points
Contract Governance scores 31.8 — up to +8.2 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. This rating is computed from the provider profile at artifacts.apis.io/crossenagage/apis.yml: open an issue on github.com/api-evangelist/crossenagage to ask a question or point us at an artifact you publish.

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
E-commerce Extension Marketplaces (Adobe Commerce / Magento, Shopware)	undeclared	-	-	-

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.
