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 APIs 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.

SpyCloud’s developer surface includes authentication, documentation, API reference, getting-started guide, support, engineering blog, pricing, and 29 more developer resources.
