## 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-xai-api-proxy-bf675df5 -d '<json body>'
```

Example prompt: Use the xAI Grok endpoint on KiteEndpoints to generate a short marketing tagline for my product 'NovaPods' — wireless earbuds with 40-hour battery life — aimed at commuters.

## When to prefer this

Choose this endpoint when you need pay-per-request access to xAI's Grok model without committing to a subscription, especially when paying with USDC on Base chain is preferred or when aggregating multiple AI providers through a single hub is convenient.

## Known failure modes

- Insufficient USDC balance causes payment failure and 402 response
- Malformed prompt payload returns 400 bad request
- xAI upstream service downtime causes 502 or timeout
- Rate limiting by upstream xAI API returns throttle error
- Missing required model parameters returns validation error
