## 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 researcher-now-url-analyzer-a66355d1 -d '<json body>'
```

Example prompt: Can you analyze this article for me — https://www.nytimes.com/2024/01/15/tech/ai-chips.html — and give me a cited summary plus all the key factual claims it makes?

## When to prefer this

Use this endpoint when you have a single specific URL — an article, YouTube video, X/Twitter video, or podcast episode — and need a cited summary and extracted claims from it. It is ideal for research pipelines that must attribute findings to sources. Prefer this over general web search when the URL is already known and deep per-document analysis is needed rather than broad topic coverage. If you need to research a topic across many sources, consider the sibling deep-research endpoint instead.

## Known failure modes

- Invalid or inaccessible URL returns an error (e.g. paywalled or private content)
- Unsupported URL type (e.g. raw PDF, live stream) may fail or return partial results
- Very long media content may increase cost and latency significantly
- Rate limiting or temporary service unavailability
- Transcription errors for low-quality audio or non-English content

## How this service works

Analyze one URL — an article, a YouTube/X video, or a podcast episode — and receive a cited summary + extracted claims. POST a JSON body { url }. Variable price per request (media transcription costs more).

## Output

Returns a structured response containing a cited summary of the content at the provided URL and a list of extracted claims, each linked back to the source. For media (video, podcast), the content is first transcribed before analysis. The result enables downstream fact-checking, research synthesis, or knowledge extraction workflows.
