## 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 tanod-web-trends-attention-3be9f5e9 -d '<json body>'
```

Example prompt: Compare public attention trends for 'artificial intelligence', 'machine learning', and 'deep learning' over the last 90 days — I want to see Wikipedia views, Hacker News activity, and news mentions, including whether each topic is rising or falling.

## When to prefer this

Choose this endpoint when you need objective, multi-signal public attention data (Wikipedia views, Hacker News, news mentions) for topic comparison or trend monitoring — rather than Google Trends data, which is not available here. Ideal when you want to compare 2–5 topics side by side, detect attention spikes, see related trending topics, or analyze attention across multiple Wikipedia language editions. Prefer this over general web search endpoints when the goal is quantitative trend analysis rather than content retrieval.

## Known failure modes

- Topic not found on Wikipedia — returns found: false with no daily data for that topic
- Date range exceeds 365 days — clamped or rejected
- End date in the future — clamped to yesterday
- More than 5 topics supplied — validation error
- Language code not matching an available article — language listed in languages_skipped
- News data unavailable for the requested date range — available: false with unavailable_reason
- Hacker News query returns partial results — partial: true flag in hacker_news object

## How this service works

Web tools: search, page to Markdown or screenshot, company profile and jobs, sitemaps, RDAP, IP.

## Output

A JSON object with per-topic daily data including Wikipedia page views (broken down by language), Hacker News story and comment counts, news mention counts, trend direction (rising/stable/falling) with 7-day and 28-day percentage changes, spike day detection, total views summary, and optionally up to 10 related/rising Wikipedia topics. Attribution metadata for each data source is included.
