## 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 video-total-load-time-check-4cf50110 -d '<json body>'
```

Example prompt: Can you check the total load time for the video at https://example.com/media/intro.mp4 and tell me how long it takes to fully load?

## When to prefer this

Use this endpoint when you need to measure the complete, end-to-end load time specifically for a video resource (as opposed to overall page load, image load, or script load time). It is purpose-built for video assets and is distinct from sibling endpoints that measure connection setup time or other resource types.

## Known failure modes

- Video URL is unreachable or returns non-2xx HTTP status
- URL does not point to a video resource
- CSS selector matches no element or multiple elements
- Provided URL is not a valid public HTTP(S) address
- Request times out if the video resource is extremely large or slow
- Invalid user_agent string format rejected by pattern validation

## How this service works
