## 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 x402-tools-hub-text-summarizer-624846ea -d '<json body>'
```

Example prompt: Can you summarize the following article for me into a short, readable overview? Here's the text: 'Artificial intelligence is rapidly transforming industries across the globe, with companies investing billions in machine learning infrastructure...'

## When to prefer this

Use this endpoint when you need a quick, micropayment-gated AI summarization of arbitrary text without setting up your own LLM infrastructure. Suitable for agents that occasionally need to condense documents or articles and prefer pay-per-call pricing over subscription models.

## Known failure modes

- Empty or missing text field returns a validation error
- Extremely long text may exceed processing limits or timeout
- Insufficient USDC balance causes payment failure and 402 response
- Malformed JSON body returns 400 bad request
- Service unavailability on Vercel deployment returns 503
