Is this price correct? Confirm a crypto asset's spot price before your agent trades, quotes, or settles on it. A signed price oracle and price feed for any ticker: Bitcoin (BTC), Ethereum (ETH), Solana (SOL) or any USD/USDT-quoted symbol. Cross-checks up to five venues (Coinbase, Kraken, OKX, Binance, CoinGecko) for a median exchange rate, requires at least two live sources, and flags divergence when they disagree. Returns a signed attestation your agent can cite.
