SingVerify Scam Sniffer API
Detects whether a user is on an active voice call at the moment they attempt a high-value transaction, a signal used to interdict authorised-push-payment and social-engineering fraud. This is Singtel's counterpart to the CAMARA anti-fraud / Scam Signal work, branded and operated by Singtel rather than published as a CAMARA-named product. Product page only — no API reference, no OpenAPI, no sandbox; access is via enterprise enquiry.
