Request a Score for a Phone Number

Signals API lets you retrieve scoring for a number based on phone number intelligence, machine learning and a data consortium.
https://api.sgnls.co/v1/score/{PhoneNumber}?email={email}&ip={ip}
where number is the mobile phone number with an international country code for example +441368792875, IP is an Internet Protocol address associated with the checking phone number, for example 188.64.144.36, and email is the email address associated with the checking phone number, for example someone@server.com. Both IP and email parameters are optional.
When you send the number, the score and other details about the phone number come back in the body of the response:
{
"reference_id": "DFHPIFKIC3VHHXV48IY2YCXS6HCMQXMM",
"updated_on": "2020-06-26T09:24:35.000000Z",
