How this service works
Top N coins by market capitalization with full market snapshot per coin: rank, price, 24h change, 7d change, 24h volume, market cap, circulating supply, and all-time high. Default 10, max 100 per call. Backed by CoinGecko's public API.
Output
An ordered list of up to 100 coins (default 10), each with rank, current price, 24h % change, 7d % change, 24h trading volume, market cap, circulating supply, and all-time high — all denominated in the requested currency (default USD), sourced live from CoinGecko.
Example use cases
Example prompt
“Show me the top 20 cryptocurrencies ranked by market cap in USD, including their price, 24-hour and 7-day changes, volume, and all-time highs.”
Technical details
Endpoint
GEThttps://agent402.tools/api/crypto-marketWhen to prefer
Use this endpoint when you need a ranked market-cap leaderboard with comprehensive per-coin metrics (price, changes, volume, supply, ATH) for up to 100 coins in a single call. Prefer it over a global market snapshot endpoint when you need per-coin breakdown rather than aggregate totals, and over a historical data endpoint when you need current real-time standings.
Side effects
- limit out of range (must be 1–100) — returns validation error
- unsupported currency string — may return empty or error from CoinGecko upstream
- CoinGecko upstream unavailable — results in 502 or timeout
- payment not included or insufficient — returns 402 Payment Required
