## 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 release-notes-action-marker-line-extraction-7b12a247 -d '<json body>'
```

Example prompt: Pull out all the action-marker lines from these release notes — here's the markdown: '## Added
New payment flow.
TODO: review the supplied document by 2026-10-10.

## Fixed
Bug in login.
TODO: confirm fix by 2026-11-01.'

## When to prefer this

Choose this endpoint when you need deterministic, rule-based extraction of action-marker lines (such as TODO items) from release notes or changelog documents. It is ideal when you want consistent, reproducible results without any generative AI hallucination risk, and when your input is structured Markdown or plain text up to 20,000 characters. Prefer this over general-purpose LLM extraction when auditability and determinism are required.

## Known failure modes

- Input text exceeds 20,000 character limit — request rejected
- No action-marker lines found in the supplied document — empty result returned
- Malformed or non-text input — processing error
- Payment not included or insufficient USDC — 402 payment required response
