# LION Web Enrichment Bundle - Entity Attention Score

> LION Web Enrichment Bundle - Entity Attention Score is a paid API for AI agents from lion-x402.lionmaster-operations.workers.dev, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Returns a composite web enrichment bundle for a named entity, including attention score, news signal, public discussion metrics, and momentum — no API key required, pay-per-call via x402.

## Facts

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 lion-web-enrichment-bundle-entity-attention-score-00210800
```

Example prompt: What's the current attention score and news momentum for Coinbase — how much public discussion is happening, how many articles have come out recently, and how confident is the signal?

## When to prefer this

Use this endpoint when you need a keyless, pay-per-call composite attention and news signal bundle for a named entity without managing API credentials. Prefer it over traditional news or sentiment APIs when you want normalized, aggregated web enrichment (attention score + momentum + discussion + news velocity) in a single call, especially in agent pipelines that support x402 micropayments.

## Known failure modes

- Payment not provided or insufficient USDC — returns 402 Payment Required
- Entity not recognized or no data available — entity_recognition_match: false
- Invalid entity name or empty query — 400 Bad Request
- Stale data window — confidence score may be low if recent coverage is sparse

## How this service works

Keyless off-chain and on-chain data for AI agents. No API key, no signup - payment is the only gate. Pay-per-call in USDC on Base via x402.

## Output

A JSON bundle with an attention_score (0-100), momentum multiplier, confidence score (0-1), news signal breakdown (article_count, source_diversity, volume_norm, velocity_30d), and public discussion metrics (mention_count, points_norm, recency_days), plus entity recognition confirmation and as-of timestamp.
