Crossbeam

Crossbeam is the leading Ecosystem-Led Growth (ELG) platform: a secure data-collaboration network that lets companies compare CRM data with their partners to uncover shared customers, overlapping prospects, and co-selling opportunities without exposing sensitive records. It turns partner-sourced overlaps, populations, and real-time signals into "Ecosystem Intelligence" that flows into GTM tools and AI agents. Crossbeam exposes this data through a REST Partner API (OAuth 2.0), real-time Signals webhooks, a remote MCP server, and in-app AI Chat, backed by SOC 2 Type II, GDPR, CCPA, and PCI DSS compliance.

Crossbeam is listed with 1 API on the APIs.io network: Partner API. Tagged areas include Company, Ecosystem-Led Growth, Partnerships, Account Mapping, and Co-Selling.

The Crossbeam catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Crossbeam’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, changelog, pricing, and 33 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 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/.

Agent readiness — checks not met, largest first (exact, from this profile):

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
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
Documented Reversibility +6 pts — a reversal operation in the contract, graded up when a window is documented too
Agentic Commerce Well-Known Document +5 pts — a parsing /.well-known/ucp.json or acp.json declaring a version and at least one service — `self` when its endpoints are on the provider's own domain, `platform` when they are on a vendor's

3 more unmet checks in the Agent Readiness table above.

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

Contract Quality scores 39.0 — up to +15.3 composite points
Contract Governance scores 18.2 — up to +9.8 composite points
Operational Transparency scores 55.3 — up to +5.8 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/crossbeam/apis.yml: open an issue on github.com/api-evangelist/crossbeam 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
Agent Skills (SKILL.md packages)	builds-on	43.4	-	1
Salesforce AppExchange (CRM, outbound, business-process automation)	builds-on	43.4	-	1
Zoom App Marketplace and Partner Ecosystem (builders and partners on Zoom)	builds-on	43.4	-	1
HubSpot App Marketplace (CRM add-ons, outbound, performance marketing, chat)	builds-on	43.4	-	1

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.
