## 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 apexapi-ai-summarize-50d0be56 -d '<json body>'
```

Example prompt: Can you summarize this article for me: 'Artificial intelligence is transforming industries worldwide, from healthcare to finance, as companies race to adopt large language models and automation tools to boost efficiency and reduce costs. Analysts predict the AI market will reach $1 trillion by 2030.'

## When to prefer this

Use this endpoint when you need a quick, pay-per-call AI text summarization without managing API keys, especially in agentic workflows on Base/x402 payment rails. Prefer over other summarizers when cost transparency per call and no-key access are priorities.

## Known failure modes

- Empty or missing query field returns an error
- Extremely long input may be truncated or rejected
- Vague or ambiguous input may produce a generic or low-quality summary
- Service unavailability on the Vercel-hosted endpoint may return 5xx errors
- Payment failure in USDC on Base may prevent access (402 response)
