How To Solve CORS Error When Trying to Access DHL API

I am trying to integrate DHL API for rate estimate in my website. I am using axios in the frontend to achieve this but i keep getting the CORS POLICY ERROR "Access to XMLHttpRequest at 'https://express.api.dhl.com/mydhlapi/test? from origin 'http://localhost:3000' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource."

I am not using a backend server, hence i can’t get around this error. What should i do in my code to get around this error and get the result back from the API?

here is my code:

const getRateEstimate = () => {

      const options = {
        method: 'GET',
        url: 'https://express.api.dhl.com/mydhlapi/test',
        params: {
          accountNumber: 'myaccnumber',
          originCountryCode: fromCountriesCode,
          originCityName: fromCountriesCapital,
          destinationCountryCode: toCountriesCode,
          destinationCityName: toCountriesCapital,
          weight: weight,
          length: '5',
          width: '5',
          height: '5',
          plannedShippingDate: date,
          isCustomsDeclarable: 'false',
          unitOfMeasurement: 'metric',
          
        },
        headers: {
          Authorization: 'Basic authkey',  


        }
      };
     
        axios.request(options).then((response) => {
            console.log(response.data);
            setData(response.data);
        }).catch((error) => {
            console.error(error);
        });
      }
