## 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-821542cd -d '<json body>'
```

Example prompt: Send this prompt to the GPT-5 endpoint on KiteEndpoints.ai and pay with USDC on Base: 'Write a concise executive summary of the following quarterly earnings report: [report text].'

## When to prefer this

Choose this endpoint when you need GPT-5 inference on a pay-per-request basis without committing to an OpenAI subscription, especially when paying with USDC on Base chain via the x402 protocol. Useful for AI agents that need occasional GPT-5 calls billed directly in crypto rather than through a traditional API key.

## Known failure modes

- Payment failure if wallet lacks sufficient USDC on Base chain
- 402 Payment Required if x402 payment header is missing or malformed
- Model unavailability if GPT-5 endpoint is offline or rate-limited by upstream provider
- Malformed request body returning 400 error
- Empty or stub response if the underlying GPT-5 routing is not yet live
