Prices
by Onchain Query API in Onchain & crypto
Spot USD prices for up to 20 crypto assets in ONE call: pass tickers (eth, btc, sol), CoinGecko ids, or 0x token addresses (priced from live DEX pairs). Each entry returns price_usd, 24h change and market cap where known; unknown symbols are reported, not silently dropped. Use it to value a portfolio, size a trade, or refresh a price table without 20 round trips.
