## 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 oblique-markets-text-summarizer-9b086721 -d '<json body>'
```

Example prompt: Summarize the following article as bullet points — keep it concise and factual: [paste article text here].

## When to prefer this

Choose this endpoint when you need fast, deterministic text summarization with a predictable output format (bullets, paragraph, or one-liner) and hard length guarantees. Prefer it over general-purpose LLM calls when repeatability and cost-predictability matter, or when you're operating in a pipeline that requires structured summarization at scale for a fixed per-call fee.

## Known failure modes

- Input text exceeds hard input cap — returns error indicating text is too long
- Invalid or missing format parameter — returns validation error
- Empty or blank input text — returns error or empty summary
- Payment not received or invalid x402 payment header — returns 402 Payment Required
- Model timeout if input is near the cap boundary — may return partial or error response
