Cannot post and Retrieve data via Gaia Rest API Calls

I need to try out Gaia Rest API at https://docs.blockstack.org/storage/write-to-read.html

To post and get data to and from Gaia storage here is what the API says.

PUT/store/<public-key-hash>/<file-name> it is use to write data to user gaia service on behalf user by applications
GET/store/<public-key-hash>/<file-name> reads file from user defined by public key hash.

my question is what is the full http/https url address for posting and retrieving data via Gaia rest API.

The documentation says to use https://myservice.org/

so I tried https://myservice.org/store/my_publickey-will-be-here/content.json

but nothing is posted to my gaia storage
