I copied the demo code using axios into my script and run it.
The code works in the browser client of rapidapi.com, but I get the error:

{
message: ‘Parameter [text|html|url|html_fragment] not found’,
code: ‘error.missingParameter’,
data: { parameter: ‘text|html|url|html_fragment’ },
error: true
}

I am not able to use the API. 😦
