import axios from 'axios';
const options = {
method: 'POST',
url: 'https://openai80.p.rapidapi.com/chat/completions',
headers: {
'content-type': 'application/json',
'X-RapidAPI-Key': '1866c61022msh3aaec9e4e3dbd10p1ca0c3jsn614c71037588',
'X-RapidAPI-Host': 'openai80.p.rapidapi.com'
},
data: {
model: 'gpt-3.5-turbo',
messages: [
{
role: 'user',
content: 'Hello!'
}
]
}
};
try {
const response = await axios.request(options);
console.log(response.data);
} catch (error) {
console.error(error);
}
Here is the example of simple python app:
We can create an amazing app using this api. Let’s create a chatbot using it.
import requests
api_key = 'YOUR_API_KEY'
x_host = 'YOUR_HOST_URL'
url = 'https://openai80.p.rapidapi.com/chat/completions'
headers = {
'X-RapidAPI-Key': api_key,
'X-RapidAPI-Host': x_host
}
def chat_with_gpt3(prompt):
payload = {
'model': 'gpt-3.5-turbo',
'messages': [ {'role': 'system', 'content': 'You are a helpful assistant.'},
{'role': 'user', 'content': prompt} ]
}
try:
response = requests.post(url, json = payload, headers = headers)
response_data = response.json()
reply = response_data [ 'choices' ] [ 0 ] [ 'message' ] [ 'content' ]
return reply
except Exception as e:
print(f'Error: {str(e)}')
return None
# Example usage
user_input = input('User: ')
while user_input.lower() != 'exit':
bot_response = chat_with_gpt3(user_input)
print('ChatGPT Bot:', bot_response)
user_input = input('User: ')
Here is the output:
this is the loop conversation between you and your bot. And this is how we can simply create a chatbot using this open ai’s api.

Thanks to RapidAPI’s integration with OpenAI’s ChatGPT API, developers now have an amazing opportunity to access the power of ChatGPT at no cost. By following the steps outlined in this blog post, you can create chatbot applications that spark engaging conversations, delighting your users
