## 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 llm-toll-groq-llama-3-3-70b-chat-summarization-7def75c4 -d '<json body>'
```

## When to prefer this

Choose this endpoint when you need a pay-per-call LLM chat or summarization capability without a subscription, especially in agentic pipelines that support x402 micropayments. It is ideal for low-volume, on-demand text generation tasks where you want to pay exactly $0.01 USDC per request. Prefer this over self-hosted models when latency matters and you need the quality of Llama 3.3 70B via Groq's fast inference infrastructure.

## Known failure modes

- Missing or malformed messages array returns a 400 validation error
- Payment not included or insufficient USDC balance causes a 402 Payment Required response
- Groq API backend unavailability returns a 502 or 503 error
- Messages array containing unsupported content types may be silently ignored or cause errors
- Rate limits from the underlying Groq service may cause transient 429 errors
