Nagios

Nagios is a family of open-source and commercial IT infrastructure monitoring tools, including Nagios Core (the original open-source monitoring engine), Nagios XI (the commercial enterprise distribution), Nagios Fusion, Nagios Log Server, and Nagios Network Analyzer, used to monitor hosts, services, networks, applications, and metrics with alerting and reporting. Nagios Core itself has no central HTTP API; Nagios XI ships a built-in REST API (typically reached at https://{nagios-xi-host}/nagiosxi/api/v1/) for reading, writing, deleting, and updating monitoring configuration and status. The Nagios XI API is authenticated via a per-user API key passed as a query parameter or header. Passive check results can also be submitted via NRDP (HTTP, JSON/XML) or NSCA (encrypted TCP, port 5667), and the NCPA cross-platform agent exposes a hierarchical REST API on port 5693.

Nagios publishes 13 API contracts indexed on the APIs.io network, including Config API, CPU API, Disk API, and 10 more. Tagged areas include Monitoring, Infrastructure Monitoring, Network Monitoring, Open Source, and IT Operations.

The Nagios catalog on APIs.io includes 1 JSON-LD context and 3 Spectral governance rulesets.

Nagios’ developer surface includes authentication, documentation, pricing, engineering blog, and 28 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
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)
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link

10 more unmet checks in the Agent Readiness table above.

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

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
Configuration-Management Content Registries (Ansible Galaxy, Chef Supermarket)	builds-on	17.2 (thin)	-	-

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.
