## 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 x402-multi-tool-api-trending-crypto-coins-78ee2446 -d '<json body>'
```

Example prompt: What are the top 10 trending cryptocurrency coins right now? I want to see which tokens are getting the most attention in the market today.

## When to prefer this

Choose this endpoint when you need a real-time snapshot of which cryptocurrencies are currently trending by market interest and activity, especially for discovery of emerging or popular tokens. Prefer this over a general crypto price lookup when you don't have specific coins in mind and want to surface what's hot right now. It's pay-per-request with no API key required — ideal for agents that need occasional trending data without a subscription.

## Known failure modes

- Payment not included or invalid x402 USDC payment header — returns 402 Payment Required
- limit parameter is a non-integer or negative value — may return validation error or default result set
- Upstream CoinGecko API unavailable — may return 502 or empty data
- Requesting a limit larger than the available trending coins — returns fewer results than requested without error
- Rate limits on underlying provider may cause intermittent failures

## How this service works

Pay-per-request data toolkit for AI agents — 13 no-auth tools, $0.005 USDC each via x402. Web search, read URL, crypto price/markets/trending, Wikipedia, news headlines, weather, FX rates, IP geolocation, DNS lookup, stock quotes, and domain WHOIS.

## Output

Returns a JSON object with a 'coins' array where each entry includes the coin's id (e.g. 'pudgy-penguins'), human-readable name, ticker symbol, and market_cap_rank. Also includes a 'total' count of results returned. The list is ordered by trending score/market activity.
