Error with Amazon Comprehend (Sentiment)

Hi everyone, i am trying to use the Amazon Comprehend (Sentiment) but it shows me this error:
Execute failed: Missing Authentication Token (Service: Comprehend, Status Code: 400, Request ID: f5592b7e-5d9e-4485-ae29-b11c3a53d9c8)


Is there any solution apart from having a access key or account? Or is that the only way

Hi @Marcus_Yong_En and welcome to the forum.

You can find out more about Amazon Comprehend pricing below. There is a free tier, but you do have to be logged into an actual account - anonymous credentials won’t work for this service.

I see thank you very much
