Keyfactor

Keyfactor is a machine-identity and PKI (public key infrastructure) company that provides a control plane for digital trust — helping organizations discover, issue, automate, and govern cryptographic keys and certificates across enterprise, cloud, DevOps, and IoT environments. Its core products are Keyfactor Command (certificate lifecycle automation at scale), EJBCA Enterprise (modern, quantum-ready PKI and certificate authority), SignServer / Signum (code signing and verification), Cloud PKI-as-a-Service, and cryptographic discovery and inventory. Keyfactor Command and EJBCA expose REST APIs (self-hosted or cloud, per customer) with official Go, .NET, and CLI clients, and an experimental MCP server for agentic-AI integration. Keyfactor is trusted by roughly 40% of the Fortune 500 and is backed by Insight Partners.

Keyfactor is profiled on the APIs.io network. Tagged areas include Company, Cybersecurity, PKI, Machine Identity, and Certificate Lifecycle.

Keyfactor’s developer surface includes documentation, getting-started guide, support, engineering blog, signup flow, CLI, authentication, and 14 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):

Machine-Readable Contract +18 pts — api_specs includes an OpenAPI document
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)
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)

11 more unmet checks in the Agent Readiness table above.

Operational Transparency scores 13.2 — up to +11.3 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.

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.
