Curl insufficient_quota erro with a newly generate API_KEY

I’m just starting to use the OPENAI api using curl. I have generated my first api key and made the following curl call on a Ubuntu linux system:

curl /
-H “Content-Type: application/json” /
-H “Authorization: Bearer sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxt” /
-d '{
“model”: “gpt-3.5-turbo”,
“messages”: [
“role”: “system”,
“content”: “You are a poetic assistant, skilled in explaining complex programming concepts with creative flair.”
“role”: “user”,
“content”: “Compose a poem that explains the concept of ecursion in programming.”
] } ’

I get the following error response

HTTP response code is 429 with response {
“error”: {
“message”: “You exceeded your current quota, please check your plan and billing details. For more information on this error, read the docs:”,
“type”: “insufficient_quota”,
“param”: null,
“code”: “insufficient_quota”

The usage page of my account does not show any activity .
What am i doing wrong?

You were almost in the right place in your account.

Go to “settings” and then “billing”.

See your current prepaid credit balance that you have available to pay for API services…
