Live bid/ask/last, 24 h change, volume and range for a pair on Kraken, Coinbase and OKX side by side — with the cross-venue spread. Queries each venue's public ticker in parallel. OKX quotes in USDT when USD is asked for. The cross-venue spread shows arbitrage gaps and which venue is off. When to use: For top-of-book prices; for how much size the book can absorb use orderbook_depth. Price: $0.001 per call (10 free/day; after that a payment-required result lists x402 options). Errors: returns isError with a message for invalid input or an upstream failure (not charged).

}Live USD price and 24 h change for up to 30 crypto assets on any chain — by symbol, CoinGecko id, contract or mint address. Resolves each asset (BTC, "coingecko:ethereum", "base:0x…", a bare 0x address with chain, or a Solana mint) and prices it from DefiLlama's aggregated oracle (confidence score included). Symbols resolve against the top 1,000 coins by market cap first, so "USDC" means the real one; ambiguous symbols list the alternatives. When to use: For current prices by symbol on any chain; for Solana mints by address use price (on the A.U.G.U.R Synapse · Wallets & Risk server, https://augur-trade.com/hub/mcp/risk); for history use price_history. Price: free. Errors: returns isError with a message for invalid input or an upstream failure (not charged).
