How this service works
Live cross-asset market data: the top coins ranked by market cap with price, market cap, 24h change and volume (CoinGecko). The global snapshot an agent reads before trading — our other price tools are Base-token-address based; this is the whole market. Pass limit= (up to 100) and vs= (usd/eur/…). Not financial advice.
Output
A ranked list of up to 100 cryptocurrencies, each with: coin name, symbol, current price in the requested quote currency, total market cap, 24h percentage price change, and 24h trading volume. Data is sourced live from CoinGecko.
Example use cases
Pre-trade market overview for agent
“Before you do anything with my crypto portfolio, grab the top 100 coins by market cap with their current prices and 24h changes in USD so we have a full market picture.”
Daily crypto briefing in EUR
“Every morning give me a rundown of the top 20 cryptocurrencies by market cap — I want prices, market caps, and 24h movement all in EUR.”
Spot biggest movers in 24h
“Fetch the top 100 coins by market cap right now in USD — I want to see who moved the most in the last 24 hours, up or down.”
Technical details
Endpoint
GEThttps://402.com.tr/api/x402/crypto-markets?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a broad, ranked overview of the entire crypto market — top coins by market cap with price, volume, and 24h change — rather than deep data on a specific Base token address. It is the right first call before any trading decision, portfolio rebalancing, or market-awareness task where you need the global leaderboard rather than a single asset or DEX pair.
Side effects
- Invalid vs currency code returns an error or empty results
- limit above 100 may be rejected or capped
- Upstream CoinGecko outage causes stale or missing data
- Payment failure (x402) if USDC balance is insufficient
