selfie

app_id
: Your application's unique identifier.
app_key
: Your application's authentication key.

To make a liveness verification request, you can use the following examples:
var request = require('request');
var fs = require('fs');
var options = {
'method': 'POST',
'url': 'https://idv-eu.kairos.com/v0.1/liveness-verification',
'headers': {
'app_id': 'put_app_id_here',
'app_key': 'put_app_key_here'
},
formData: {
'selfie': {
'value': fs.createReadStream('/path/to/selfie_image'),
'options': {
'filename': 'selfie.jpg'
}
},
'threshold': '0.6'
}
};
request(options, function (error, response) {
if (error) throw new Error(error);
console.log(response.body);
});
Replace app_id, app_key, and selfie with your actual credentials and the path to your selfie image.
