How it uses Jev

record = {'id': row['id'], 'repeat': repeat, 'labels': row['labels'], 'rubric_version': RUBRIC['version']}
started = time.perf_counter()
try:
    request = urllib.request.Request('https://api.typesafe.ai/v1/systemone', data=json.dumps(payload).encode(),
        headers={'Authorization': 'Bearer ' + key, 'Content-Type': 'application/json'}, method='POST')
    # No retries: each record corresponds to exactly one attempted request.
    with OPENER.open(request, timeout=30) as response:
        body = json.load(response)
    metrics = {}
    for k in KEYS:
        answer = body['answers'][k]
        value = answer['noul']
        if answer['type'] != 'noul' or type(value) not in (int, float) or not math.isfinite(value) or not 0 <= value <= 1:
            raise ValueError('Invalid response schema')
        metrics[k] = value
