Selling Chat GPT API Key. ( 400 Rs)

I am broke. My manager wanted something with gen AI to show to client within 2 days. I was first trying with Llama2 but wasted all time in fixing cmake. Then hurriedly bought chat gpt api subscription with my own money . Scraped some publicly available client product data, finetuned with it, made some kind of salesperson agent. Looks like client or team has no interest in it. I have no use of api key either.
