## 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-utilpeek-topic-attention-trends-3391f932 -d '<json body>'
```

Example prompt: Has interest in 'large language models' been rising or falling over the last 90 days? Show me the Wikipedia page view trend, Hacker News activity, and news mentions, and flag any spike days.

## When to prefer this

Choose this endpoint when you need objective, open-data proxies for public interest in a topic over time — specifically Wikipedia page views, Hacker News engagement, and news mention counts. It is not Google Trends data and does not reflect search volume, but it provides multilingual Wikipedia signals across up to 6 languages and cross-source corroboration. Prefer it over general web-search trend APIs when you need reproducible, citation-backed attention data, multilingual audience signals, or spike detection grounded in Wikimedia and GDELT data.

## Known failure modes

- Topic not found on Wikipedia — returns found:false with no daily data
- Requested date range exceeds 365 days — clamped or rejected
- Language code has no Wikipedia article for the topic — listed under languages_skipped
- News coverage not yet available for the full date range — unavailable_reason returned
- More than 5 topics submitted — request rejected by schema validation
- End date in the future — clamped to yesterday automatically

## How this service works

Use when an agent must tell if interest in a topic is rising or fading: Wikipedia, Hacker News and news over time. Topic trends and attention over time: Wikipedia page views per language, Hacker News…

## Output

A JSON object per topic containing: resolved Wikipedia article title and URL, daily time-series rows with Wikipedia views per language, Hacker News story and comment counts, and news mention counts; aggregate 7-day and 28-day percentage changes; trend direction (rising/stable/falling); spike days with ratio above trailing median; optional related top/rising topics; caveats and data attribution.
