Radius attribute not factored in

Describe the bug The radius attribute is not properly factored in when scraping markets

To Reproduce

Request Endpoint: /market/scrape
Request Method: POST
Request Headers:
```
Content-Type: application/json
```

Request Body:

{
"gps_width": "49.99227538220853",
"gps_length": "8.673063982148363",
"radius": 70
}

Expected behavior What should the endpoint return? Only markets with radius <= 70m

Actual behavior _What does the endpoint return?_ Two markets with radius > 300 m. Increasing radius may result in a correct behavior.
