## 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-summarize-3cc1cfd5 -d '<json body>'
```

Example prompt: Can you summarize this article for me? Here's the text: 'The global renewable energy market has seen unprecedented growth over the past decade, driven by falling costs of solar and wind technology, supportive government policies, and increasing corporate sustainability commitments...' [full article text]

## When to prefer this

Choose this endpoint when you need a fast, high-quality text summarization powered by Llama 3.3 70B via Groq's low-latency inference. It is well-suited for agents that need to condense articles, documents, reports, or transcripts on demand and can handle micropayments via the x402 protocol at $0.02 per call. Prefer this over general LLM endpoints when summarization is the primary goal and cost-per-call predictability matters.

## Known failure modes

- Empty or missing 'text' field returns a validation error
- Extremely long inputs may be truncated or rejected if they exceed model context limits
- Payment failure (402) if USDC payment of $0.02 is not completed via x402 protocol
- Service unavailability if Railway hosting is down
- Malformed JSON request body returns 400 error
