## 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 llama-3-1-8b-chat-completion-klane402-93e04f38
```

Example prompt: Ask Llama 3.1 8B: 'Explain the difference between supervised and unsupervised learning in two sentences.'

## When to prefer this

Choose this endpoint when you need cheap, keyless LLM inference via USDC micropayment (x402 protocol) without managing API credentials. Ideal for agents that need occasional text generation at $0.002/call without committing to a subscription. Prefer over OpenAI/Anthropic hosted endpoints when cost minimization and pay-per-call billing are priorities, and Llama 3.1 8B quality is sufficient for the task.

## Known failure modes

- Missing or empty prompt parameter results in an error or empty reply
- Payment not accepted or USDC balance insufficient causes a 402 response and no completion
- Model timeout on very long prompts may result in truncated or no reply
- Malformed query string may cause server-side parsing errors
