## 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 coin-railz-trending-tokens-78685ebc -d '<json body>'
```

Example prompt: What are the top gaining and losing tokens across DEXs right now? Give me a real-time snapshot of what's trending.

## When to prefer this

Use this endpoint when an agent needs to surface which tokens are currently outperforming or underperforming across DEXs in real time — ideal for market scanners, trading signal bots, or DeFi dashboards. Prefer this over static token pricing endpoints when the goal is ranking by momentum rather than fetching price for a known token.

## Known failure modes

- No tokens returned if DEX data feed is temporarily unavailable
- Stale data if upstream CoinGecko/DEX Screener APIs are lagging
- Payment failure (402) if USDC balance is insufficient for the $0.50 per-call fee
- Timeout if querying across many chains simultaneously
- Empty result set for very low-liquidity timeframes
