## 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 css-video-src-extractor-91830821 -d '<json body>'
```

Example prompt: Can you extract the video source URL from this page — https://example.com/video-page — I need the actual video file URL from the video element's src attribute?

## When to prefer this

Choose this endpoint when you need to extract video source URLs from a public webpage or static HTML and want SSRF-safe network access. It's a paid ($0.01 USDC) alternative to the free POST /v1/sandbox/css-video-src endpoint — prefer the sandbox endpoint first and fall back to this when you need guaranteed SSRF protection or the sandbox is unavailable.

## Known failure modes

- No video element with a src attribute found on the page — returns empty or null result
- URL is blocked by robots.txt or access controls — returns an error
- SSRF-protected URL is an internal/private address — request rejected
- HTML input exceeds 200,000 character limit — validation error
- Malformed or non-public URL provided — fetch failure
- Page requires JavaScript rendering to populate video src — src may be missing

## How this service works

Call when an agent needs video sources via video[src] from a public page or HTML (SSRF-safe). Exact $0.01 USDC. Prefer unpaid POST /v1/sandbox/css-video-src first.

## Output

Returns the extracted value(s) of video[src] attributes found in the provided HTML or fetched from the given URL, giving direct links to video files embedded in the page.
