# I need to create an API
I used `header('Access-Control-Allow-Origin: *')` in api.php and when making a request using `fetch` with javascript gives me an error saying something from CORB, how do I fix it?
## PHP:
```php
header('Content-Type: application/json');
header('Access-Control-Allow-Origin: *');
echo '{"message":"hello"}';
```
## JS:
```auto
fetch('example.infinityfreeapp.com').then(res=>res.json()).then(data=>{
console.log(data);
});
```
That’s my code.

Yeah, right now I just read that it wasn’t possible, so it’s a concern not being able to make an API, I understand that it’s for security, but it’s annoying, I have to agree that infinityfree is free, for which I appreciate
