## 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 distilbart-cnn-abstractive-text-summarizer-fffa91a9 -d '<json body>'
```

Example prompt: Can you summarize the following article into a short paragraph? Here's the text: [paste up to 4000 characters of the article].

## When to prefer this

Choose this endpoint when you need abstractive (rewritten, not extractive) summarization of short-to-medium text blobs up to ~4k characters, and you want per-call micropayment billing via onchain USDC settlement. It's well-suited for pipelines that process news, support tickets, or documents one at a time and need a compact, human-readable summary rather than bullet extracts.

## Known failure modes

- Text exceeds ~4k character limit — request rejected or truncated
- Empty or missing 'text' field — validation error returned
- Model inference timeout on very dense or complex input
- Payment settlement failure via x402 — call not processed
- Non-English input may produce degraded or incoherent summaries

## How this service works

Abstractive summarization of caller-provided text (up to ~4k chars). Model: distilbart-cnn. Always-on, verified onchain settlement.

## Output

Returns an abstractive summary of the submitted text — a rewritten, condensed version capturing the main ideas, not just extracted sentences. Typically a few sentences to a short paragraph depending on input length.
