## 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 tempest-ai-content-engine-condense-summarize-7c977a2c -d '<json body>'
```

Example prompt: Can you condense this 800-word article into a bullet-style summary of no more than 100 words? Here's the text: [paste article]. Keep it concise and factual.

## When to prefer this

Use this endpoint when you need to shorten or summarize existing text content via a pay-per-call API without managing AI infrastructure. Prefer this over general-purpose LLM APIs when you want a pre-built summarization endpoint with built-in USDC micropayment billing. Best for pipelines that need summarization as a discrete, billable step.

## Known failure modes

- Input text shorter than 50 characters — validation error
- Missing required 'text' field — 400 bad request
- Payment not included or insufficient USDC — 402 payment required
- Text too large for context window — upstream AI error
- Invalid style parameter value — may default or return error
- Network timeout on AI backend — 500 or timeout error

## How this service works

Compose, rewrite, translate, and refine content at scale. 25 AI-powered endpoints. Pay-per-call with USDC on Tempo.

## Output

Returns a JSON object with a 'success' boolean and a 'data' object containing the condensed/summarized version of the input text, respecting the requested style and maximum length constraints.
