from requests.adapters import Retry, HTTPAdapter
API_URL = 'https://image-anonymization.p.rapidapi.com'
API_KEY = 'YOUR_RAPIDAPI_KEY' # Place your API key here
if __name__ == '__main__':
# We strongly recommend you use exponential backoff.
error_statuses = (408, 409, 429, 500, 502, 503, 504)
s = requests.Session()
retries = Retry(backoff_factor=1.5, status_forcelist=error_statuses)
s.mount('https://', HTTPAdapter(max_retries=retries))
url = f'{API_URL}/v1/results'
with open('img.jpg', 'rb') as f:
api_res = s.post(url, headers={'X-RapidAPI-Key': API_KEY},
files={'image': f}, timeout=20)
api_res_json = api_res.json()
# Handle processing failure.
if (api_res.status_code != 200 or
api_res_json['results'][0]['status']['code'] == 'failure'):
print('Image processing failed.')
sys.exit(1)
response_entities = api_res_json['results'][0]['entities']
image_format = response_entities[0]['format'].lower()
path_to_image = f'result.{image_format}'
with open(path_to_image, 'wb') as img:
img.write(base64.b64decode(response_entities[0]['image']))
objects_pretty = json.dumps(response_entities[1]['objects'], indent=2)
print(f'? Hidden objects:\n{objects_pretty}\n')
