## 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 youtube-comments-scraper-stableapify-dev-2d5223e5 -d '<json body>'
```

Example prompt: Scrape all comments from this YouTube video — https://www.youtube.com/watch?v=dQw4w9WgXcQ — and give me the full comment text and posting dates, up to 500 comments.

## When to prefer this

Use this endpoint when you need to extract YouTube comments at scale without hitting the YouTube Data API's strict quotas, when you need full comment text and metadata from multiple videos in one run, or when you need a pay-per-call model rather than managing your own API credentials and quota limits.

## Known failure modes

- Invalid or unavailable YouTube video URL returns an error or empty dataset
- Comments disabled on the video results in an empty dataset
- Insufficient memory allocation causes the actor run to fail
- Invalid input schema (missing video URL) returns a 400 error
- Actor run timeout if too many comments requested with insufficient resources
- Payment failure via x402 prevents run from starting

## How this service works

Start the "YouTube Comments Scraper" Apify actor (streamers/youtube-comments-scraper). This alternative YouTube Data API has no limits or quotas. Extract YouTube comments data from one or multiple YouTube videos: full comment text, posting date,…

## Output

Returns an Apify actor run object with a run ID, status (READY), actor ID, start timestamp, default dataset ID where results will be stored, and a JWT access token to poll for results or retrieve the scraped comment data.
