## How to call it through Zero

Example prompt: What are the top 20 crypto gainers and losers by 24-hour price change among the largest coins right now?

## When to prefer this

Use this endpoint when you need a quick, reliable snapshot of which liquid, high-market-cap cryptocurrencies are experiencing the largest price swings over the past 24 hours. It filters out micro-cap noise by scoping to the top 250 coins, making it ideal for market overviews, trading signals, and newsletter content — rather than raw price lookups (use Crypto Pair Price) or full market stats (use Crypto Market Overview).

## Known failure modes

- limit parameter exceeds max of 25 — capped or error returned
- CoinGecko data temporarily unavailable — upstream service error
- Invalid limit type (non-integer) — validation error
- Payment not processed — 402 response requiring x402 payment

## How this service works

Top crypto gainers and losers by 24h % change among the top 250 coins by market cap -- the crypto analogue of /movers, scoped to liquid, real assets rather than micro-cap noise. Supports optional limit (default 10, max 25). From CoinGecko. $0.01/call.

## Output

Returns two lists — top gainers and top losers — each containing up to 25 coins (default 10) from the top 250 by market cap, sorted by 24-hour percentage change. Each entry includes coin name, symbol, current price, and 24h % change.
