LRN (Number Intelligence) API

LRN (Number Intelligence) API

The Pronto LRN API will allow you to scrub your lists prior to sending SMS or MMS messages.  It will allow you to determine if a number is a wireless number or not, capable of receiving a message or not and who the carrier is.

The API endpoint is: https://api.prontoconnects.com/v1.5/lrn/lrn-lookup

It is a POST requiring the following headers:

Content-Type: application/json
X-Account-Id: your Pronto account ID, the same one that you use when sending messages
Authorization: Bearer {your_api_key} (the same API key used for sending messages)

The JSON body/request payload is:

{
  "tn": "5097341345"
}

And the response payload:

{
  "number": "5097341345",
  "lrn": "15096190000",
  "enhanced": {
    "carrier": "Charter IP Enabled Services",
    "carrier_type": "IPES",
    "city": "Kennewick",
    "zip_code": "99336",
    "county": "Benton",
    "timezone": "-0800",
    "state": "WA",
    "rate_center": "KENNEWICK",
    "lata": "676",
    "ocn": "792K"
  },
  "messaging": {
    "enabled": false,
    "provider": "Charter Fiberlink, LLC",
    "country": "United States",
    "country_code": "US",
    "reference_id": null
  }
}

The key things to attention to are "carrier_type" (WIRELESS, WRSL, PCS and PCSR indicate a mobile number) and "messaging.enabled" which indicates if a number if capable of receiving text messages.
