About LayerCall
LayerCall provides a unified Trust Intelligence API for fraud prevention that scores identity signals in a single request. It evaluates IP addresses, email addresses, phone numbers, domains and devices to produce a 0–100 risk score with an allow, review or block verdict. The service combines device fingerprinting, AI agent authorization and multiple fraud signals to detect sophisticated fraud attempts such as VPN usage, disposable emails or automated browsers. Real-time intelligence is maintained through feeds refreshed every six hours, including Tor exit nodes, commercial VPNs and abuse lists. The API supports 15 endpoints covering identity verification, domain intelligence, phone validation and custom rule management. Responses include detailed breakdowns of top signals in plain language, enabling precise decision-making without black-box scoring. Processing times are typically under 0.1 seconds for cached lookups and 1–4 seconds for first-time requests that query external DNS and RDAP servers.
