## 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-dex-gainers-losers-0ea64ef7 -d '<json body>'
```

Example prompt: What are the top gaining and losing tokens on Ethereum right now? Show me the biggest movers from the last 24 hours across DEXs.

## When to prefer this

Use this endpoint when you need a ranked list of top gaining and losing tokens across DEXs in real time, especially when you want to filter by a specific blockchain or custom timeframe. Prefer this over general price APIs when the goal is to surface market momentum and volatility leaders rather than look up a specific token's price.

## Known failure modes

- Invalid chain parameter returns error or empty results
- Unsupported timeframe value may return default 24h data or an error
- Service unavailable during high network congestion
- Payment failure (insufficient USDC) results in 402 response blocking access
- Empty results if no significant movers detected for the given filter combination
