## 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 scrapfly-substack-crawler-4bf72814 -d '<json body>'
```

Example prompt: Can you scrape this Substack post and give me the full article content? The URL is https://example.substack.com/p/my-newsletter-post

## When to prefer this

Choose this endpoint when you specifically need to extract content from Substack newsletter pages — posts, author pages, or publication homepages — and want a structured response without managing browser automation yourself. Prefer this over generic web scrapers when Substack-specific rendering or anti-bot handling is required.

## Known failure modes

- Invalid or non-Substack URL returns success: false
- URL is behind a hard paywall that blocks crawling
- Network timeout or upstream crawl failure
- Malformed URL input causes request rejection
- Rate limiting if too many requests are made in quick succession
