## 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-transcript-scraper-via-apify-stableapify-dev-02270ef2 -d '<json body>'
```

Example prompt: Can you grab the full transcript from this YouTube video — https://www.youtube.com/watch?v=dQw4w9WgXcQ — and include timestamps so I can see when each line is spoken?

## When to prefer this

Choose this endpoint when you need to programmatically extract the transcript of one or more YouTube videos, especially when you want optional timestamps and are already operating in an x402/USDC micropayment environment. It is preferable to manual caption downloads or YouTube API quota-limited approaches, and it wraps the Apify actor ecosystem so no separate Apify account is needed.

## Known failure modes

- Video has no captions or auto-generated transcript available — returns empty or error
- Invalid or private YouTube URL — actor run fails with an error response
- Network timeout if the video is very long or Apify infrastructure is slow
- Payment failure via x402 if wallet has insufficient USDC balance
- Rate limits or actor errors on the Apify platform side

## How this service works

Search Apify Store actors, start actor runs, and fetch results over x402 and MPP.

## Output

Returns either a joined plain-text string of the full transcript or an array of timestamped transcript segments (each with start time and text), depending on the timestamps flag. The response is delivered synchronously after the Apify actor run completes.
