With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability x402-data-hub-v2-exchange-rates-36c551c4 -d '' ``` Example prompt: What's the current exchange rate for BTC to USD and ETH to USDC right now? Pull it from the x402 Data Hub exchange rates endpoint. ## When to prefer this Choose this endpoint when you need real-time or near-real-time crypto exchange rates and are operating in an x402 micropayment-compatible agent environment. It is well-suited for agents that already handle x402 payment flows and need price data without setting up a dedicated exchange API key. At $0.05 per call it is cost-effective for low-to-moderate frequency lookups rather than high-frequency trading feeds. ## Known failure modes - Payment not included or insufficient — returns 402 Payment Required - Invalid or unsupported trading pair — returns 400 or empty result - Rate data temporarily unavailable — may return 503 or stale data - Malformed POST body — returns 400 Bad Request - Network timeout from upstream exchange data source ## How this service works 16 paid endpoints - Crypto, Exchange, Yield, Governance, Sentiment ## Output Returns current exchange rate data for the requested cryptocurrency pair(s), including the rate value, base and quote currency identifiers, and a timestamp indicating data freshness.
