Using the Synchronous HLR Lookup API

The synchronous API processes one cell phone number (MSISDN) per request and returns results in real time in the response body of the HTTP REST API request. Results are presented as JSON and can be used for real-time mobile network routing and monitoring.

A synchronous API call consists of an HTTP request and response. Your server submits exactly one MSISDN (cell phone number) number and receives the HLR lookup results immediately in the HTTP response body in JSON format. This is normally the best option for real time use cases such as phone number validation, voice over internet or SMS routing.
