## 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-gpt-5-api-f04611a4 -d '<json body>'
```

Example prompt: Can you use the KiteEndpoints GPT-5 proxy to generate a detailed business plan outline for a sustainable urban farming startup — pay with USDC per request?

## When to prefer this

Choose this endpoint when you need access to GPT-5 capabilities on a pay-per-request basis using USDC on Base chain — ideal for AI agents operating in crypto-native environments, for use cases where a standing OpenAI subscription is impractical, or when you want to avoid committing to a monthly plan. Particularly useful in agentic workflows that already handle x402 micropayments.

## Known failure modes

- Insufficient USDC balance causes 402 Payment Required response
- Malformed request payload results in error or empty result object
- GPT-5 model unavailability or upstream OpenAI outage causes 5xx errors
- Rate limiting if too many concurrent requests are submitted
- Ambiguous or missing prompt field leads to generic or empty model output
