OpenAI GPT-3 API error 429: "Request failed with status code 429"

I'm trying to connect OpenAI API to my Vue.js project. Everything is OK but every time I try to POST request, I get a 429 status code (too many request) but I didn't even had the chance to make one. Any help?

Response:

My method in Vue.js:

async handleSelect() {
      try {
        const res = await fetch("http://localhost:8000/", {
          method: "POST",
          headers: {
            "Content-Type": "application/json",
          },
          body: JSON.stringify({
            question: this.selectedOption,
          })
        })

        const data = await res.json();
        console.log(data);
      } catch {
        console.log(data);
      }
    }

on server side

app.post("/", async (req, res) => {
  try {
    const question = req.body.question;

    const response = await openai.createCompletion({
      model: "text-davinci-003",
      prompt: `${question}`,
      temperature: 0, // Higher values means the model will take more risks.
      max_tokens: 3000, // The maximum number of tokens to generate in the completion. Most models have a context length of 2048 tokens (except for the newest models, which support 4096).
      top_p: 1, // alternative to sampling with temperature, called nucleus sampling
      frequency_penalty: 0.5, // Number between -2.0 and 2.0. Positive values penalize new tokens based on their existing frequency in the text so far, decreasing the model's likelihood to repeat the same line verbatim.
      presence_penalty: 0, // Number between -2.0 and 2.0. Positive values penalize new tokens based on whether they appear in the text so far, increasing the model's likelihood to talk about new topics.
    });
    // console.log(response);
    res.status(200).send({
      bot: response.data.choices[0].text,
    });
  } catch (error) {
    // console.error(error);
    res.status(500).send(error || "Something went wrong");
  }
});

As stated in the official OpenAI article:

> This (i.e., 429) error message indicates that you have hit your assigned rate
> limit for the API. This means that you have submitted too many tokens
> or requests in a short period of time and have exceeded the number of
> requests allowed. This could happen for several reasons, such as:
>
> - You are using a loop or a script that makes frequent or concurrent requests.
>
> - You are sharing your API key with other users or applications.
>
> - You are using a free plan that has a low rate limit.
