## 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-social-attention-signals-f7de6b08
```

Example prompt: What's the current social attention and news momentum score for Coinbase — I want the attested confidence score and article count so I can verify it offline.

## When to prefer this

Choose this endpoint when you need cryptographically attested social and media attention signals for a named company or entity, especially in agent pipelines where offline verification of data provenance matters. Prefer over unattested enrichment APIs when auditability is required, or over flat-bundle services when you only need attention/signal data and want to pay per call rather than a subscription.

## Known failure modes

- Entity name not recognized — entity_recognition_match returns false
- Payment not received or USDC balance insufficient on Base — 402 response
- Unknown entity string returns low-confidence result with sparse signals
- Rate limiting or network timeout on upstream signal aggregation
- Stale data if upstream news sources are delayed

## Output

A JSON object containing an attention_score (0-100), momentum value, confidence score, news_signal breakdown (volume_norm, velocity_30d, article_count, source_diversity), public_discussion metrics (points_norm, mention_count, recency_days), entity_recognition_match boolean, and an asset_id — all timestamped and Ed25519-attested for offline verification.
