What exactly do you want to control via API?

Thanks for the feedback.

I want to have it detect me and send information via the API to trigger contexts that are specific to me. Or send a welcome home notification to the ceiling speaker.

Run this script as resident. Change host variable to your camera IP and auth variable to access credentials in username:password format. Make sure that Basic auth mode (not digest) is set on your camera. Then post what you get in LM Logs when running this script.
Code:
local json = require('json')
local socket = require('socket')
local mime = require('mime')

local host = '192.168.1.1'
local auth = 'user:password'

local sock = socket.tcp()
sock:settimeout(15)

local res, err = sock:connect(host, 80)

if not res then
  sock:close()
  log('connect failed', err)
  os.sleep(5)
  return
end

local function init()
  local crlf = '\r\n'

  sock:send(
    'GET /FR/events/live/json?heartbeat=10 HTTP/1.1' .. crlf ..
    'Host: ' .. host .. crlf ..
    'Authorization: Basic ' .. mime.b64(auth) .. crlf .. crlf
  )
end

local function parse(resp)
  resp = json.pdecode(resp)
  log(resp)
end

init()
local pat, len = nil, nil

while true do
  res, err = sock:receive(pat)
  log('rx', pat, res, err)

  if err then
    sock:close()
    log('receive error', err)
    break
  end

  if type(pat) == 'number' then
    pcall(parse, res)
    pat, len = nil, nil
  elseif #res == 0 then
    pat = len
  elseif not len then
    len = res:match('Content%-Length: (%d+)')
    len = tonumber(len)
  end
end

Thanks for the reply.
I am sending the log again as attached file.
Please help me.

You need to trigger a face detection event and check if it's logged. You can disable the log call on line 40 to filter out debug info:
Code:
-- log('rx', pat, res, err)
