crimsoncrawler-com

Crimson Crawler provides a CVE intelligence API that aggregates data from multiple threat‑intelligence sources to deliver a single, cross‑referenced attack narrative. Users submit a CVE identifier, IoC, product, or technique and receive severity scores, exploit likelihood, adversary attribution, an SSVC verdict, and exportable audit‑ready reports. The service offers REST endpoints, Python and TypeScript SDKs, a CLI, and an MCP server for flexible integration.

crimsoncrawler-com is listed with 2 APIs on the APIs.io network. Tagged areas include API, CVE, Threat-Intelligence, Security, and Data-API.

The crimsoncrawler-com catalog on APIs.io includes 1 JSON-LD context and 1 Spectral governance ruleset.

crimsoncrawler-com’s developer surface includes CLI, changelog, authentication, documentation, API reference, getting-started guide, support, and 24 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):

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
Request/Response Examples +7 pts — share of operations carrying request/response examples; else an Examples / Code Samples link
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)
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document

8 more unmet checks in the Agent Readiness table above.

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

Contract Quality scores 45.6 — up to +13.6 composite points
Access Clarity scores 44.7 — up to +11.1 composite points
Developer Ergonomics scores 59.5 — up to +8.1 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/crimsoncrawler-com/apis.yml: open an issue on github.com/api-evangelist/crimsoncrawler-com to ask a question or point us at an artifact you publish.
