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 keyed by symbol (e.g. BTC, ETH, SOL) containing: USD price, Binance USDT price, Coinbase USD price, 24h percentage change, list of source URLs, and an updated_at ISO timestamp.
Example use cases
Trading bot pre-trade price check
“Before placing my trade, pull the latest multi-venue spot prices for BTC and ETH — I need the Binance and Coinbase quotes side by side plus the 24h change.”
Crypto portfolio snapshot
“Give me the current USD prices for BTC, ETH, and SOL from multiple exchanges so I can see how my portfolio is valued right now.”
Price discrepancy alert
“Check the live prices of BTC on Binance and Coinbase and tell me if there's a meaningful spread between them and what the 24h move looks like.”
Technical details
Endpoint
GEThttps://kr-x402-mvp.kgy5612.workers.dev/v1/price?utm_source=zero.xyzWhen to prefer
Choose this endpoint when an AI agent needs real-time multi-venue crypto spot prices with no API key setup, paid frictionlessly via x402 USDC micropayment on Base. It is ideal for trading bots, onchain agents, or portfolio dashboards that need aggregated Binance + Coinbase quotes and 24h change in a single call. Prefer it over exchange-specific APIs when venue comparison or failover is needed, and over subscription APIs when pay-per-call economics are preferred.
Side effects
- Missing or invalid symbols parameter returns default BTC/ETH/SOL data
- Payment failure via x402 (insufficient USDC balance) results in 402 Payment Required response
- Upstream exchange API unavailability may cause missing venue prices or stale data
- Unsupported or misspelled token symbol may return empty price object
- Rate limiting or worker downtime returns 5xx error
