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 with a 'prices' map keyed by symbol, each containing the median USD price, per-exchange prices, 24h percent change, and possibly volume. Also includes a list of source exchange URLs used and an 'updated_at' ISO timestamp. Dispersion in basis points and n_sources indicate data reliability.
Example use cases
Trading bot price check
“Pull the current median spot price of BTC and ETH in USD from multiple exchanges, including the 24h change and how many sources responded.”
Onchain agent portfolio valuation
“I need live USD prices for BTC, ETH, SOL, and BNB to calculate the current value of my crypto portfolio — can you fetch the latest aggregated spot prices?”
Crypto market alert monitoring
“What's the current price of DOGE and XRP in USD and how much have they moved in the last 24 hours? I want to know if there's a big swing.”

Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/crypto/price/btc-usd?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a robust, multi-source median spot price for major cryptocurrencies in USD with reliability metadata (n_sources, dispersion_bps). It is particularly well-suited for trading agents, onchain bots, or portfolio apps that need tamper-resistant price data not sourced from a single exchange. Pay-per-call at $0.003 USDC via x402 makes it cost-effective for low-frequency lookups without subscription overhead.
Side effects
- If fewer than the expected exchanges respond, n_sources will be lower and the median may be based on a limited sample
- Stale prices if all upstream exchanges are temporarily unreachable — check updated_at
- Requested symbol not supported returns an error or empty entry (supported: BTC, ETH, SOL, BNB, XRP, DOGE, ADA, AVAX, LINK, SUI)
- Payment failure (x402) if USDC balance on Base is insufficient — returns 402 status
- High dispersion_bps may indicate exchange pricing anomalies or latency issues
