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. Payment of $0.05 USDC is charged per call via x402 protocol.
Example use cases
Live portfolio valuation in USD
“I need to know the current USD price of BTC, ETH, and SOL so I can calculate the total value of my crypto portfolio — can you look up the latest exchange rates for all three?”
Arbitrage spread monitoring
“What's the current exchange rate for ETH to USDC on the x402 Data Hub right now? I want to compare it to what I'm seeing on my other feed to spot any price discrepancies.”
DApp trade price display
“My app needs to show users the live rate for WBTC to ETH before they confirm a swap — can you fetch the current exchange rate for that pair?”
Technical details
Endpoint
POSThttps://data-hub-x402.vercel.app/api/exchange/rates?utm_source=zero.xyzWhen to prefer
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.
Side effects
- 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
