Signadot

Signadot is a Kubernetes-native platform for validating microservices and AI-generated code changes against real dependencies before merge. Its core is environment virtualization: large numbers of lightweight ephemeral "sandboxes" spin up in seconds by routing request-level traffic to only the changed services on a shared cluster, without duplicating the whole stack. Testing capabilities — Jobs (Playwright/Cypress/k6 runners), Smart Tests (AI regression detection), and Plans (reusable validation workflows) — layer on top, and a bundled MCP server plus installable Agent Skills let coding agents (Cursor, Claude Code, Codex) provision environments and validate their own work. Signadot installs as a Kubernetes operator, integrates with service meshes and CI/CD, and exposes a REST control-plane API, a CLI, and a Go SDK.

Signadot publishes 5 API contracts indexed on the APIs.io network, including Cluster API, Orgs API, ResourcePlugins API, and 2 more. Tagged areas include Company, Developer Tools, Kubernetes, Testing, and Ephemeral Environments.

The Signadot catalog on APIs.io includes 1 Spectral governance ruleset.

Signadot’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, pricing, signup flow, and 23 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):

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
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
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)

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
Cloud Native (Kubernetes, CNCF, FinOps)	mixed	44.1	-	-
Backstage Plugin Directory	mixed	44.1	-	-

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.

Standards implemented 2

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.
