## 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 trending-coins-835fbf3a
```

Example prompt: What cryptocurrencies are trending the most on CoinGecko right now? Give me the ranked list with their prices and 24h changes.

## When to prefer this

Use this endpoint when you need a real-time global attention signal for cryptocurrency — specifically which coins are being searched most on CoinGecko. Prefer this over Base-DEX trending-token endpoints when you want broad cross-chain market attention rather than DEX-specific trading activity. Pair with token-risk or portfolio-risk checks before acting on any coin surfaced here, as trending reflects popularity, not safety or quality.

## Known failure modes

- Upstream CoinGecko API unavailable or rate-limited — returns error with no coin data
- Stale data if CoinGecko trending feed has not refreshed recently
- Payment not processed — 402 payment required before response is served
- Empty or partial result if CoinGecko is experiencing partial outages

## How this service works

The coins most searched on CoinGecko right now, ranked, with market-cap rank, price and 24h change. A global attention/discovery feed for agents hunting what's moving — distinct from trending-tokens, which is Base-DEX specific. An attention signal, not quality or safety: vet anything here with token-risk before touching it. Not financial advice.

## Output

A ranked list of the most-searched coins on CoinGecko at the time of the call, each with its coin name, ticker symbol, market-cap rank, current price, and 24-hour price change percentage. The list reflects search/attention popularity, not quality or safety — suitable as a discovery signal only.
