Silent Push

Silent Push is a preemptive cyber defense company that maps adversary infrastructure before it is weaponized, using a continuously scanned view of the global DNS, web content, certificate and WHOIS landscape. Its platform turns that data into Indicators of Future Attack (IOFA), risk scores for domains and IP addresses, and threat intelligence feeds that security teams push into SIEM, SOAR and blocking infrastructure. The developer surface is a REST API gateway at api.silentpush.com covering enrichment, Passive Active DNS (PADNS), live web scanning and screenshots, SPQL search, feed and indicator CRUD, Threat Check, TLP reports and export in CSV, JSON, TXT, RPZ and STIX formats, authenticated with an x-api-key header. Silent Push also runs a hosted Model Context Protocol server that exposes 33 read-only investigation tools to MCP-compatible AI clients over OAuth 2.1.

Silent Push is listed with 2 APIs on the APIs.io network. Tagged areas include Company, Security, Threat Intelligence, Cybersecurity, and DNS.

Silent Push’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, signup flow, CLI, 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/.

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 github.com/api-evangelist/silent-push: open an issue to ask a question, or submit a pull request to add artifacts.

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
Domains and DNS (registrars, registries, DNS)	builds-on	46.0	-	-

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.

tagged — the provider's own APIs.json carries the standard as a tag; implementation not verified
