BitSight

Bitsight is a global cyber risk intelligence platform that combines security ratings, external attack surface management (EASM), third-party risk management (TPRM), and cyber threat intelligence (CTI) in a single data model. Its outside-in, agentless monitoring produces continuously updated security ratings validated against real-world breach likelihood, powering vendor risk workflows, insurance underwriting, and capital-markets portfolio oversight for more than 3,500 organizations across 60+ countries. Bitsight exposes a RESTful HTTP API at api.bitsighttech.com (companies, portfolios, ratings, findings, alerts, and CTI) authenticated with an API token over HTTP Basic, documented in the Bitsight Knowledge Base and an interactive Stoplight reference.

BitSight is listed with 1 API on the APIs.io network. Tagged areas include Company, Security, Cyber Risk, Security Ratings, and Third-Party Risk Management.

BitSight’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, authentication, and 17 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)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Stable Error Semantics +8 pts — OpenAPI $refs a shared error schema across 4xx/5xx responses (verified), else common[].type includes ErrorCatalog / ErrorCodes / DeclineCodes
Rate-Limit Signaling +7 pts — OpenAPI responses document X-RateLimit-* / RateLimit headers (verified), else a rate_limits artifact or RateLimits link (documented)

10 more unmet checks in the Agent Readiness table above.

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

Contract Quality scores 0.0 — up to +25.0 composite points
Contract Governance scores 0.0 — up to +12.0 composite points
Operational Transparency scores 10.5 — up to +11.6 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/bitsight/apis.yml: open an issue on github.com/api-evangelist/bitsight 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
Compliance Assurance and Cloud Attestation	builds-on	51.2	-	-
Cisco DevNet Ecosystem (builders on Meraki, Catalyst, ISE, ThousandEyes, Splunk)	builds-on	51.2	-	-
ServiceNow Store (partner apps + ServiceNow Certified App)	builds-on	51.2	-	-

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.
