## 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 cryptointel-trending-on-chain-narrative-detector-3af18687
```

Example prompt: What tokens or crypto narratives are getting unusual on-chain volume right now, before they hit mainstream attention?

## When to prefer this

Choose this endpoint when you need to identify emerging crypto narratives and tokens before they reach mainstream media coverage, specifically relying on on-chain volume anomaly detection rather than social sentiment or news aggregation. Best when the goal is early signal detection rather than confirmation of already-trending assets.

## Known failure modes

- Payment required (402) if x402 payment header is missing or insufficient
- Service unavailable if upstream on-chain data providers are down
- Empty or stale results if no tokens meet the unusual volume threshold at query time
- Rate limiting if called too frequently without valid payment
- Malformed response if Railway deployment is experiencing issues

## How this service works
