Ok, it actually does look ok.I was trying to consume it in Desktop and didn't understand why I couldn't enter a point. I was made aware that this service can take a point, line or poly as input. Because of this, no schema is set.After adding an OID field and value to your input JSON, it works.Give this a try.{
"geometryType": "esriGeometryPoint",
"spatialReference": {
"wkid": 4326
},
"fields": [
{
"name": "OID",
"type": "esriFieldTypeOID",
"alias": "OID"
}
],
"features": [
{
"attributes": {
"OID": 1
},
"geometry": {
"x": 9.4,
"y": 50.3
}
}
]
}
