Curl: could not parse the JSON body of your request

[128fefe96d5926b65fa2]

Hello forum,

I´m a newbie and have a first look on the api. I want to use curl in a windows command prompt. I copied the code from the first example:

curl …chat/completions -H “Content-Type: application/json” -H “Authorization: Bearer MyKey” -d ‘{“model”: “gpt-4o”, “messages”: [ { “role”: “system”, “content”: “You are a helpful assistant.” } ] }’

The word “myKey” is replaced with my real key.

The syntax seems to be ok, for i only copied the text.

But I got the following errormessage:

"error": {
        "message": "We could not parse the JSON body of your request. (HINT: This likely means you aren't using your HTTP library correctly. The OpenAI API expects a JSON payload, but what was sent was not valid JSON. If you have trouble figuring out how to fix this, please contact us through our help center at help.openai.com.)",
        "type": "invalid_request_error",
        "param": null,
        "code": null

Where is my mistake?

Many thanks for your help.

Welcome forumite,

Windows cmd is a bit special, you need to escape your json quotes with \"

Ignore that it says powershell, it’s cmd.

not sure if it’s an artifact of the forum or the exampl, but the curly " used may be the issue, also you only have a system prompt, I;ve added a user one, try

curl https://api.openai.com/v1/chat/completions -H "Content-Type: application/json" -H "Authorization: Bearer MY_KEY" -d "{\"model\": \"gpt-4\", \"messages\": [{\"role\": \"system\", \"content\": \"You are a helpful assistant.\"}, {\"role\": \"user\", \"content\": \"What is the capital of France?\"}]}"
