## 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 bazaar-gateway-vercel-app-a1773ece
```

Example prompt: Can you grab the title, description, and preview image for this link: https://techcrunch.com/2024/01/15/openai-announces-new-model/ — I just need the OpenGraph metadata, nothing deep.

## When to prefer this

Use this endpoint when you need to quickly scan one or more URLs for their metadata before deciding whether to invest in deeper analysis. At $0.001 per call it is 5x cheaper than the full AI web-intelligence endpoint ($0.005). Ideal for filtering, ranking, or enriching a list of links with titles/images/descriptions without parsing full page content. Choose the sibling /api/web-intelligence endpoint when you need actual page content, entity extraction, or sentiment analysis.

## Known failure modes

- URL is not publicly accessible (private or behind auth) — returns ok:false
- URL does not exist or returns 4xx/5xx — returns ok:false with error
- URL has no OpenGraph or Twitter Card metadata — returns ok:true but og/twitter fields are null
- Timeout if the target server is slow (latency up to 800ms)
- Invalid URL format — missing required query param or malformed URL

## How this service works

Fast link preview extractor — returns OpenGraph/Twitter Card metadata (title, description, image, favicon, site name, canonical URL, language) for any public URL. Perfect for agents that need to scan many links quickly before deciding which ones deserve deep analysis via /api/web-intelligence ($0.005). 5x cheaper than full AI analysis. Latency ~300-800ms.

## Output

Returns a structured object with: ok (boolean), url and final_url (after redirects), title, description, image (absolute URL), favicon, site_name, language, canonical URL, og object (OpenGraph fields), twitter object (Twitter Card fields), article metadata (author, published_at, section, tags), signals object (boolean flags for has_og_image, has_twitter_card, has_canonical, has_favicon, has_article_metadata, content_type_inferred enum), redirects count, fetched_at timestamp, _meta with call_id, and HATEOAS next actions suggesting deeper analysis endpoints.
