## 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-8945a257 -d '<json body>'
```

Example prompt: Can you scrape the content of this Substack post for me and return the article text and metadata: https://example.substack.com/p/my-article?

## When to prefer this

Use this endpoint when you need to programmatically extract and read content from Substack newsletters or posts without manual browsing. Prefer this over generic web scrapers when targeting Substack specifically, as it may include Substack-specific parsing logic.

## Known failure modes

- Invalid or non-Substack URL returns success: false
- Private or paywalled Substack post may return incomplete data
- Network timeout if the Substack page is slow to load
- Malformed URL input causes request failure
- Rate limiting or blocking by Substack results in failed extraction
