## 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 whatchuneed-llm-summarize-c8b43027 -d '<json body>'
```

Example prompt: Can you summarize the following article for me and pull out the key points? Keep the summary under 150 words: [paste of long article text here]

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call text summarization without committing to a long-term LLM subscription. It is well-suited for agents that occasionally need to condense long-form content (articles, documents, emails) and want structured output including key bullet points alongside the summary — especially in pipelines already using x402 micropayment infrastructure.

## Known failure modes

- Missing required 'text' field returns a validation error
- Text too long for processing may timeout or be truncated
- Invalid maxLength value (non-integer) causes a schema validation failure
- Network or infrastructure issues on Vercel may cause 500 errors
- Insufficient USDC balance or x402 payment failure prevents the call from completing
