How this service works
Market rankings with price, volume, market cap — filterable by category
Output
A paginated array of cryptocurrency market objects, each containing coin ID, symbol, name, current price in the requested fiat currency, market capitalization, 24-hour trading volume, price change percentages, and market cap rank. Data covers all coins or a specific category, sorted by the requested order.
Example use cases
DeFi sector market overview
“Give me the top 50 DeFi coins sorted by market cap in USD — I want to see which DeFi projects are biggest right now.”
Broad crypto market snapshot
“Fetch the first 250 cryptocurrencies by market cap and show me their current prices in USD so I can see the overall market landscape.”
Altcoin research in local currency
“List the top 100 cryptocurrencies by market cap but price them in EUR — I'm doing research for a European investor report.”
Technical details
Endpoint
GEThttps://x402engine.app/api/crypto/marketsWhen to prefer
Choose this endpoint when you need a broad, ranked list of cryptocurrency market data across many coins rather than a single coin lookup. Ideal for market overviews, sector analysis (via category filter), portfolio screening, or building dashboards. Prefer the single-coin price sibling endpoint when you only need one specific coin's price.
Side effects
- Invalid category ID returns empty results or 404
- Page number exceeding 500 returns empty array
- Limit exceeding 250 rejected with validation error
- Unsupported fiat currency code returns error
- Insufficient USDC balance causes 402 payment failure before data is returned
