How this service works
Pay-per-call crypto microdata for trading/onchain AI agents via x402 (USDC on Base): Base gas, token risk, balances, multi-venue prices, Hyperliquid book/funding, kimchi premium. No API keys.
Output
A JSON object containing BNB spot price in USD from multiple venues (Binance USDT price, Coinbase USD price), a blended/reference price_usd, 24-hour percentage change, list of data source URLs, and an updated_at ISO timestamp indicating data freshness.
Example use cases
Trading bot price check
“My trading bot needs the live BNB/USD price pulled from Binance and Coinbase right now, including how much it's moved in the last 24 hours — can you grab that?”
Arbitrage spread monitor
“Pull the current BNB price from multiple venues so I can see if there's a spread between Binance and Coinbase worth acting on right now.”
Onchain agent portfolio valuation
“I need to value my BNB holdings in USD — fetch the latest multi-exchange BNB/USD price and show me which sources you used and when the data was last updated.”

Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/crypto/price/bnb-usd?utm_source=zero.xyzWhen to prefer
Choose this endpoint when your AI agent needs real-time BNB/USD price data from multiple venues simultaneously without managing API keys, and when pay-per-call USDC micropayments via x402 on Base fit your cost model better than a subscription. It's ideal for autonomous onchain trading agents, DeFi bots, or portfolio valuation tools that need cross-exchange price comparison with 24h momentum data in a single call.
