## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability kiteendpoints-ai-free-chatgpt-proxy-0547459b -d '<json body>'
```

Example prompt: Can you use the KiteEndpoints ChatGPT proxy to generate a response to this question: 'What are the main differences between supervised and unsupervised machine learning?' — just send the prompt and get back the AI answer.

## When to prefer this

Choose this endpoint when you need on-demand ChatGPT-style text generation without a direct OpenAI subscription, want to pay per-request with USDC on Base chain, or are building an agent that needs occasional LLM responses without committing to a monthly API plan. Useful for crypto-native workflows where x402 micropayment is preferred.

## Known failure modes

- Payment of 0.19 USDC not received — 402 Payment Required returned
- Invalid or missing prompt in request body — malformed response
- ChatGPT upstream API unavailable — 503 or gateway error
- Rate limiting on the proxy layer — request throttled
- Empty or null result returned if prompt is filtered by content policy
