Hi!
Please switch the single and double-quotes for the valid json post body like so:

```
curl --request POST --url https://sales-tax-calculator.p.rapidapi.com/rates --header "content-type: application/json" --header "x-rapidapi-host: sales-tax-calculator.p.rapidapi.com" --header "x-rapidapi-key: ****" --data '{"city": "New York","state": "NY","street": "48 E 12th St","zip": "10003"}'
```
