CertiK

CertiK is a leading Web3 security platform that combines AI, formal verification, and expert audits to secure blockchain protocols and smart contracts. Its Partner (Skynet) API exposes CertiK's security intelligence to integrators: the Skynet Security Score API returns comprehensive, multi-metric security scores for blockchain projects (score, rank, tier, percentile, highlights and alerts), and the Token Scan API returns real-time on-chain security analysis of token contracts across major chains (token info, market and holder data, a SkyKnight score, and a severity-ranked security summary). Access is by partner API key issued by the CertiK Business Team, sent in the X-Certik-Api-Key header against https://partner.certik-skynet.com. CertiK is a portfolio company of Insight Partners, Lightspeed Venture Partners, SoftBank Vision Fund and Wing Venture Capital.

CertiK publishes 2 API contracts indexed on the APIs.io network: Security Score API and Token Scan API. Tagged areas include Company, Cybersecurity, Web3, Blockchain, and Smart Contract Security.

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

CertiK’s developer surface includes documentation, API reference, authentication, changelog, engineering blog, support, and 19 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 does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

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):

MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
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)

5 more unmet checks in the Agent Readiness table above.

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

Contract Quality scores 13.9 — up to +21.5 composite points
Access Clarity scores 26.3 — up to +14.7 composite points
Operational Transparency scores 28.9 — up to +9.2 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/certik/apis.yml: open an issue on github.com/api-evangelist/certik 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
LF Decentralized Trust (Hyperledger) Members and Projects (enterprise blockchain, digital identity, CBDC)	standard	26.8 (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.
