Data Adapter (HTTP JSONPath) issue

I’m trying to use macvendorlookup api with a data adapter but json file seems to be ununderstandable to graylog because it starts with a [ instead of {

sample call : https://www.macvendorlookup.com/api/v2/ac-b4-80-d8-12-0a

answer :
[{“startHex”:“ACB480000000”,“endHex”:“ACB480FFFFFF”,“startDec”:“189891241574400”,“endDec”:“189891258351615”,“company”:“Dell Inc.”,“addressL1”:“One Dell Way”,“addressL2”:“Round Rock TX 78682”,“addressL3”:“”,“country”:“US”,“type”:“MA-L”}]

i guess I’ve tried all : $, $[0], $.[0], $.company…

There’s another API but it returns string not json :
https://api.macvendors.com/ac-b4-80-d8-12-0a

Graylog 6.1
Debian 12

For those who are interrested, I use another API (https://api.maclookup.app/v2/macs/${key})
No workaround found :confused:
