Fetching duco api is crashing my repl

[rocketpipoca]

as you can see, after i run this code

fetch('https://server.duinocoin.com/balances/Rui')
  .then(response => response.json())
  .then(data => console.log(data))
  .catch(error => console.error(error));

the whole thing crashes

probably to enforce https://replit.com/terms:

you may not and may not allow any third party, including your end users, to:
…“mine” bitcoins, other cryptocurrencies,

but i’m not mining, im just fetching my user balance. where can i contact support to be able to run that code?
