SpyCloud

SpyCloud is an Austin, Texas based identity threat protection company that operates one of the largest repositories of recaptured darknet data — breach records, infostealer malware logs, phishing captures and combolists — and exposes it programmatically through a family of high-volume REST APIs. Security, fraud, identity and investigations teams query recaptured credentials, session cookies, exposed PII and infected-device telemetry to prevent account takeover, ransomware, session hijacking and online fraud. The public API surface spans nine separately-licensed products: Enterprise (Employee) ATO Prevention, Consumer ATO Prevention, Cybercrime Investigations, Data Partnership, IDLink identity correlation, Compromised Credit Card, Prospecting, NIST Password check, and Session Identity Protection. All are REST/JSON, authenticated with an x-api-key header, IP allow-listed, cursor-paginated at 1,000 records per page, and backed by a 99.9% uptime SLA.

SpyCloud publishes 7 API contracts indexed on the APIs.io network, including Breach API, Check API, Compass API, and 4 more. Tagged areas include Cybersecurity, Threat Intelligence, Identity, Fraud Prevention, and Account Takeover.

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

SpyCloud’s developer surface includes authentication, documentation, API reference, getting-started guide, support, engineering blog, pricing, and 31 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
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
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)
Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks

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
Cisco DevNet Ecosystem (builders on Meraki, Catalyst, ISE, ThousandEyes, Splunk)	builds-on	44.1	-	-

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.
