Sinch Number Lookup API
Overview
Queries phone numbers for carrier, line type, porting, SIM swap, VoIP detection, and reassigned number detection. Used for fraud prevention, routing, and data enrichment. One number per request — no batch endpoint.
Agent Instructions
Before generating code, gather from the user: approach (SDK or direct API calls) and language (Node.js, Python, Java, .NET/C#, curl). Do not assume defaults.
When the user chooses SDK, refer to sinch-sdks for installation, client initialization, and language-specific references. Note: Number Lookup is only supported in Node.js and Python (partial) SDKs — for Java and .NET, use direct HTTP calls.
