GET /finance/crypto
live
Live crypto prices via CoinGecko. Pass symbol=BTC (or ETH, SOL...) or CoinGecko id=bitcoin; batch up to many with commas (symbols=BTC,ETH,SOL). Returns USD (or any vs) price, 24h change, market cap, 24h volume and last update. Built for AI agents needing crypto price, token price, spot price and market data. 加密货币实时价格行情。 Accepts payment on Base or Solana — either network works.
Verdict: live. The unpaid GET reached a valid 402 (confirmed by the re-probe of 2026-10-01). The live amount equals the catalog price.
