## 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 agentrxi-llama-3-2-3b-chat-completions-7acb6e0e
```

Example prompt: Using the Llama 3.2 3B model on AgentRXI, translate the following sentence into French with a maximum of 50 tokens: 'The weather is beautiful today.'

## When to prefer this

Choose this endpoint when you need a fast, cheap, keyless LLM inference call billed in USDC per token with no account registration — ideal for agent pipelines that require lightweight text generation, classification, or translation tasks and want to avoid managing API keys or monthly subscriptions. Prefer it over larger models when low cost and low latency matter more than reasoning depth.

## Known failure modes

- Missing required 'prompt' query parameter returns a 400 error
- Payment failure or insufficient USDC balance returns a 402 Payment Required
- Rate limits or server overload may return 429 or 503
- Very long prompts exceeding context window may be truncated or rejected
- temperature or max_tokens out of valid range may return 422
