## 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 asterpay-ai-text-summarizer-171d32f0 -d '<json body>'
```

Example prompt: Can you summarize this for me? Here's the article: 'Artificial intelligence has transformed the way businesses operate, enabling automation of complex tasks, real-time data analysis, and personalized customer experiences at scale. From healthcare diagnostics to financial forecasting, AI applications are rapidly expanding across industries...' — I just need the short version with how much it was reduced.

## When to prefer this

Choose this endpoint when you need a quick, AI-generated summary of any freeform text and want metadata like reduction percentage and word count alongside the summary. It is well-suited for agents handling document digestion, research assistance, or content curation pipelines where cost per call ($0.004 USDC) is acceptable and the response latency needs to be fast rather than batch.

## Known failure modes

- Empty or missing 'text' field returns an error
- Extremely large text inputs may be truncated or rejected
- Non-textual or binary input will fail to produce a meaningful summary
- Network timeouts on very long texts
- Payment failure (insufficient USDC balance) results in 402 response
