# Attention Index

> Attention Index is a paid API for AI agents from api.agentstools.dev, paid per call via x402, $0.04/call, status unknown (last checked 2026-09-13).

Returns a 0-100 composite attention score for any word or entity by fusing Wikipedia pageviews with GDELT global news coverage volume, including WoW/MoM deltas and spike timestamps.

## 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 attention-index-5c711ead
```

Example prompt: What's the attention index for 'OpenAI' right now — give me the 0-100 score, and show me whether it's up or down compared to last week and last month, looking back over the past 90 days?

## When to prefer this

Choose this endpoint when you need a real-time, fused attention metric that combines encyclopedic readership (Wikipedia pageviews) with global news volume (GDELT) into a single normalized score — distinct from Google Trends or search interest signals. It is ideal for tracking public curiosity spikes around entities like companies, people, products, or topics, especially when you need WoW/MoM deltas and timestamped spike detection in one call rather than assembling raw signals yourself.

## Known failure modes

- Keyword cannot be resolved to a Wikipedia article — returns error or zero score for obscure/misspelled terms
- Ambiguous keyword maps to wrong article — use explicit 'article' parameter to override resolution
- Lookback window outside 14-365 day range returns validation error
- Unsupported language project code returns schema validation error
- Very new entities with minimal Wikipedia/GDELT history may return low-confidence or zero scores
- Rate limiting or payment failure (x402) if USDC balance is insufficient

## How this service works

Attention index for any word/entity fusing Wikipedia readership (Wikimedia pageviews, resolved word->article and disambiguated by real traffic) with the global news stream (GDELT coverage volume). Returns a 0-100 index, WoW/MoM deltas, datestamped spikes and a trend in one call. An attention/curiosity index over Wikipedia and world news — not Google Trends / Google search interest.

## Output

A JSON object containing a normalized 0-100 attention index for the queried keyword, derived from fused Wikipedia pageview data and GDELT news coverage. Also includes week-over-week (WoW) and month-over-month (MoM) percentage deltas, a list of datestamped spike events, and an overall trend direction — all in a single API response.
