## 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 api-vibe-airforce-12040aa4 -d '<json body>'
```

Example prompt: Use Nansen to screen tokens and show me which ones have the highest smart money activity and notable on-chain signals right now.

## When to prefer this

Use this endpoint when you need Nansen's institutional-grade on-chain analytics to screen tokens by smart money behavior, wallet activity, and blockchain signals — especially when you want to filter the crypto market down to actionable token candidates rather than just fetching price data.

## Known failure modes

- Invalid or missing filter parameters return an empty result set
- Nansen data provider unavailable causes 502/503 error
- Payment not completed (402) blocks access to results
- Rate limiting if called too frequently
- Empty response if no tokens match the given criteria
