How this service works
Crypto market tickers (replacement for the closed Nomics ticker API): rank, name, symbol, price, 24h volume, market cap, circulating/total/max supply, % change over 15m, 1h, 24h, 7d, 30d, 1y, all-time high price/date and distance from it, in USD or another quote (EUR, GBP, JPY, TRY, BTC, ETH). Top coins by rank, or specific CoinPaprika ids (btc-bitcoin, eth-ethereum). Data from CoinPaprika's public API.
Output
Returns a JSON object containing a results array of coin objects, each with: current price, market cap, 24h trading volume, all-time high (price, date, % below ATH), price change percentages (15m, 1h, 24h, 7d, 30d, 1y), symbol, rank, total supply, max supply, and last-updated timestamp. Also includes the quote currency used, result count, data source URL, and the checkedAt timestamp.
Example use cases
Real-time portfolio valuation
“I hold Bitcoin and Solana — can you pull the current USD prices and market caps for btc-bitcoin and sol-solana so I can see what my portfolio is worth right now?”
Top crypto leaderboard check
“Give me the top 20 cryptocurrencies ranked by market cap with their current prices in USD, including 24-hour and 7-day percent changes.”
All-time high comparison in EUR
“Can you fetch the current price and all-time high data for btc-bitcoin and eth-ethereum quoted in EUR so I can see how far they are from their peaks?”
Technical details
Endpoint
GEThttps://api.chainmarket-api.workers.dev/api/finance/nomics-crypto?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time crypto price and market data (price, volume, market cap, ATH, multi-timeframe % changes) for one or more specific coins by their CoinPaprika IDs, or want a ranked top-N list — especially in a pay-per-call, no-signup context using x402 micropayments on multiple chains. Prefer it over manual CoinPaprika API access when you want a pre-integrated, agent-friendly interface with no API key management.
Side effects
- Invalid or unrecognized CoinPaprika coin ID returns an error or omits that coin from results
- limit parameter out of range (not 1–100) may return a validation error
- Unsupported quote currency returns an error
- Payment failure results in no charge and no data returned
- Rate or availability issues with the upstream CoinPaprika source may cause stale or missing data
