## 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 vextorium-text-summarizer-fd6a02b6 -d '<json body>'
```

Example prompt: Can you summarize this article for me? Here's the text: 'The European Central Bank held interest rates steady at its latest meeting, citing easing inflation but flagging continued uncertainty around global trade tariffs. Officials noted that domestic demand remains subdued...' — just give me the key bullet points.

## When to prefer this

Choose this endpoint when you need a quick, cost-effective ($0.01 USDC) bullet-point summary of a text passage up to 12,000 characters, especially within a larger Vextorium-based agent workflow that already uses x402 micropayments. Prefer it over general-purpose LLM summarization when you want a lightweight, pay-per-call approach without managing your own model infrastructure.

## Known failure modes

- Text exceeds 12,000 character limit — request rejected or truncated
- Empty or missing 'text' field — likely returns an error or empty summary
- Ambiguous or low-quality input text may produce generic or unhelpful bullet points
- Rate limiting or payment failure via x402 protocol if USDC balance is insufficient
