## 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-chatgpt-4o-api-9e0a92b1 -d '<json body>'
```

Example prompt: Ask GPT-4o to write a detailed product description for my new ergonomic standing desk called 'ElevateDesk Pro', highlighting its health benefits and modern design, and pay for it with USDC via KiteEndpoints.

## When to prefer this

Choose this endpoint when you need GPT-4o inference capability but want to pay per request using USDC cryptocurrency on Base chain instead of maintaining an OpenAI subscription or API key. Ideal for agents operating in crypto-native environments or when avoiding recurring subscription costs.

## Known failure modes

- Payment failure: insufficient USDC balance on Base chain results in 402 error
- Invalid or missing prompt body returns an error response
- OpenAI upstream downtime causes 503 or timeout
- Rate limits from underlying OpenAI API may cause throttling
- Malformed JSON input may result in parse errors
