## 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-eeaca944 -d '<json body>'

## When to prefer this

Choose this endpoint when you need a ChatGPT-style text generation capability on a pay-per-use basis without committing to an OpenAI subscription, or when building an autonomous agent that pays for AI inference with USDC on the Base blockchain via x402. It is well-suited for low-volume, sporadic AI text generation tasks where per-request crypto micropayments are preferred over monthly billing.

## Known failure modes

- Insufficient USDC balance or failed x402 micropayment — returns 402 Payment Required
- Malformed request body — returns 400 Bad Request
- Upstream OpenAI API unavailability — returns 502 or 503 error
- Rate limiting or quota exceeded on the underlying ChatGPT API — returns 429
- Empty or null prompt submitted — may return empty or generic response
