Example use cases
Pre-trade price sanity check
“Before I execute this trade, can you pull the latest BTC and ETH prices from both Binance and Coinbase and tell me if they're within 0.5% of each other?”
Daily portfolio briefing
“Give me today's prices for BTC, ETH, and SOL and how each one has moved over the last 24 hours — I want a quick market snapshot for my morning review.”
Arbitrage spread detection
“Fetch the current BTC price on Binance versus Coinbase right now — I want to see if there's a meaningful spread between the two venues.”

Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/defillama/prices?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent needs real-time multi-venue crypto prices without setting up API keys, especially in autonomous onchain or trading agent contexts where pay-per-call USDC micropayments via x402 are preferable to subscription billing. Ideal when you want cross-venue price comparison (Binance vs Coinbase) and 24h change in a single call for BTC, ETH, SOL, or other major tokens.
