How this service works
Crypto price monitoring for AI agents: spot price, 24h ticker, batch quotes, and threshold alerts. Public market data via Binance Vision. Pay with USDC via x402 — no API keys.
Output
Returns a JSON object containing the symbol (e.g. 'BTCUSDT') and its current spot price (e.g. {"price": 78000, "symbol": "BTCUSDT"}), sourced from Binance Vision public market data. May also include 24h ticker data or threshold breach status depending on the request type.
Example use cases
Real-time BTC price check
“What's the current spot price of Bitcoin in USDT right now?”
ETH threshold alert for trading bot
“Check if Ethereum has crossed $3,500 USDT and alert me if it has — my trading bot needs to know before placing an order.”
Batch crypto quotes for portfolio dashboard
“Get me the current prices for BTCUSDT, ETHUSDT, and SOLUSDT so I can update my portfolio dashboard.”

Endpoint
POSThttps://agent-prices.annushka1190.workers.dev/v1/monitor/checkWhen to prefer
Choose this endpoint when you need lightweight, pay-per-call crypto price checks or threshold monitoring without setting up API keys or accounts. Ideal for AI agents that need on-demand spot prices or 24h ticker data for major crypto pairs, especially in automated workflows where cost predictability per-call matters. Prefer alternatives with WebSocket feeds if you need continuous streaming rather than discrete checks.
