AlienVault

AlienVault is the security company behind the Open Threat Exchange (OTX), one of the largest open threat-intelligence communities in the world. OTX lets security practitioners and researchers create and share "pulses" — curated collections of indicators of compromise (IOCs) such as malicious IPs, domains, hostnames, URLs, file hashes, and CVEs — and consume that shared intelligence to automatically update their defensive infrastructure. The OTX DirectConnect API provides programmatic access to subscribed pulses, indicator detail lookups across multiple facets (general, geo, malware, passive DNS, reputation, URL lists), pulse and user search, and indicator submission for analysis. Authentication is via an X-OTX-API-KEY header. AlienVault was acquired by AT&T in 2018, becoming AT&T Cybersecurity, and OTX now operates under the LevelBlue brand. An official Python SDK (OTXv2) is published on PyPI and GitHub.

AlienVault publishes 4 API contracts indexed on the APIs.io network, including Indicators API, Pulses API, Search API, and 1 more. Tagged areas include Company, Security, Threat Intelligence, Cybersecurity, and Open Threat Exchange.

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

AlienVault’s developer surface includes documentation, API reference, signup flow, 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 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
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
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

9 more unmet checks in the Agent Readiness table above.

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

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.
