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 the current AVAX/USD price from multiple venues (Binance USDT, Coinbase USD), the 24-hour percentage change, list of data sources used, and an ISO timestamp of when the data was fetched.
Example use cases
Automated AVAX trading signal
“Check the current AVAX/USD price across Binance and Coinbase and tell me if it's moved more than 2% in the last 24 hours — I want to know if it's time to rebalance my position.”
Cross-exchange price comparison
“What's AVAX trading at on Binance versus Coinbase right now? Show me both prices and any spread between them.”
Onchain agent portfolio valuation
“Grab the latest AVAX price in USD so I can calculate the current dollar value of my AVAX holdings.”

Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/crypto/price/avax-usd?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a no-API-key, pay-per-call AVAX/USD price with multi-venue aggregation (Binance + Coinbase) and 24h change data, especially in autonomous onchain agent contexts that already handle x402 USDC micropayments on Base. It is ideal over free public endpoints when you want to avoid key management overhead and only pay for what you use.
Side effects
- Symbol not supported — returns error if a non-AVAX or unsupported symbol is queried at this path
- Payment failure — x402 micropayment not completed or USDC balance insufficient on Base
- Upstream exchange API unavailable — one or more price sources may be missing or stale
- Rate limit or worker timeout — Cloudflare Worker may return 5xx under heavy load
- Stale data — timestamp may lag if upstream feeds are delayed
