You just need to set it your component's state using the setState function. A possible scenario might be:

componentDidMount() {
  fetchSomeData().then((data) => {
    this.setState({value: data})
  });
}
/* ... later, in your render function */
<input value={this.state.value} />

For more information on how setState works (and to learn more about the entire React lifecycle), see https://reactjs.org/docs/react-component.html#setstate

All you need is to initialize a state. After fetching your api call, update the state and you can use that state in input value:

<input value={this.state.value} />
