You should use a useEffect as so, you can learn more about this hook here

import React, { useState, useEffect } from "react";
import axios from "axios";

const Details = () => {

  const [data, setData] = useState(null);

  const apiDetails = () => {
    axios
      .get(`https://api.coingecko.com/api/v3/coins/${"ethereum"}`)
      .then((response) => {
        // console.log(response);
        //setData({
        //  name: response.data.name,
        //  id: response.data.id,
        // });
        return response;
      });
  };

 useEffect(() => {  
  (async () => {
   const response = await apiDetails(); 
   setData({
      name: response.data.name,
      id: response.data.id,
    });
  })();
 }, [])

  if (data) {
   return (
      <>  
       <h1>{data.name}</h1>
       <h1>{data.id}</h1>
      </>     
   );
  }  

  return null;  
};

export default Details;
