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.
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles SpyCloud the way a machine reads it — 22 machine-readable artifacts across 7 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — SpyCloud scores 54.0/100 (developing), with a separate agent-readiness read of 51/100 (agent ready). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile SpyCloud
Each block below is one kind of artifact we hold for SpyCloud. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 7
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.
SpyCloud Breach API
The Breach API from SpyCloud — 23 operation(s) for breach.
SpyCloud Check API
The Check API from SpyCloud — 2 operation(s) for check.
SpyCloud Compass API
The Compass API from SpyCloud — 5 operation(s) for compass.
SpyCloud Data API
The Data API from SpyCloud — 2 operation(s) for data.
SpyCloud Query API
The Query API from SpyCloud — 3 operation(s) for query.
SpyCloud Stats API
The Stats API from SpyCloud — 2 operation(s) for stats.
SpyCloud Watchlist API
The Watchlist API from SpyCloud — 5 operation(s) for watchlist.

MCP Servers 1
Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

MCP SERVERRate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.
Spycloud Rate Limits
RATE LIMITSSecurity Posture 4
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
Authentication, domain security, vulnerability disclosure, and trust-center signals.
Agentic Access 1
An x-agentic-access contract marks which operations are safe for an agent to run on its own and which need a human in the loop. It is the difference between an API an agent can use and one it can use safely.
Recommended x-agentic-access execution contracts for AI agents.

This is an independent, third-party profile of SpyCloud, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
