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
Returns a JSON object with a `prices` map keyed by symbol, each containing the median USD spot price, per-exchange prices (Binance USDT, Coinbase USD, etc.), 24h change percentage, number of contributing sources, and dispersion in basis points. Also includes a list of source URLs and an `updated_at` timestamp.
Example use cases
Real-time portfolio valuation for trading bot
“Get me the latest USD prices for BTC, ETH, and SOL so I can calculate the current value of my portfolio.”
Cross-exchange price dispersion check
“What's the current SOL price in USD and how much are the prices diverging across Coinbase, Kraken, and Binance right now?”
24h price change alert monitoring
“Check the current prices and 24-hour percentage changes for BTC, ETH, SOL, DOGE, and XRP — I want to know if anything has moved more than 5% today.”
Technical details
Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/crypto/price/sol-usd?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a robust, multi-source median price rather than a single-exchange quote, especially when price manipulation resistance or cross-exchange dispersion visibility matters. Ideal for AI trading agents, portfolio valuation, or any workflow that needs a single pay-per-call price fetch without managing multiple exchange API keys. Use when you need SOL, BTC, ETH, or other top-10 altcoin prices with 24h metrics in one call.
Side effects
- Unsupported symbol requested — only BTC, ETH, SOL, BNB, XRP, DOGE, ADA, AVAX, LINK, SUI are supported
- All upstream exchanges unavailable — median cannot be computed, response may be empty or error
- Payment not completed — x402 payment required at $0.003 USDC per call on Base network
- Stale data — if exchanges are slow, the updated_at timestamp may lag by seconds
- Network timeout on workers.dev edge — transient 5xx error
