## 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-deployer-x402-deployer-workers-dev-2cb9f07c -d '<json body>'
```

Example prompt: Can you summarize the following 10,000-character article into bullet points with a professional tone and keep it medium length? Here's the text: [article text]

## When to prefer this

Use this endpoint when you need to programmatically summarize long-form text content (up to 30k chars) and want flexible output formats (TLDR, bullets, paragraph, or executive summary) with control over tone and length. Prefer this over general LLM calls when you want a pay-per-use, specialized summarization endpoint without managing your own Mistral API key.

## Known failure modes

- Input text exceeds 30,000 character limit — returns error
- Unsupported summary format specified — returns validation error
- Empty or too-short input text — returns error or minimal summary
- Mistral API timeout or unavailability — returns upstream error
- Payment not processed — returns 402 Payment Required
