How this service works
PerCall is an x402 payment gateway selling live crypto market data to AI agents and developers. No accounts, no API keys: request, receive HTTP 402, pay in USDC on Base, get data.
Output
A JSON object containing the trading pair symbol (e.g. 'BTCUSDT'), the current spot price as a decimal string (e.g. '67432.15000000'), and a UTC timestamp of when the price was retrieved.
Example use cases
Live BTC price for trading bot
“Fetch the current live price of BTCUSDT so my trading bot can decide whether to execute a buy order.”
ETH portfolio valuation
“What is the real-time spot price of ETHUSDT right now? I need it to calculate the current value of my ETH holdings.”
SOL price alert check
“Check the current price of SOLUSDC for me — I want to see if it has crossed $150 before triggering my alert.”
Technical details
Endpoint
GEThttps://percall.kimi.pro/api/x402/price/%7Bsymbol%7DWhen to prefer
Use this endpoint when you need a single, real-time spot price for a specific crypto trading pair and want zero-friction access — no API key, no account, just pay $0.001 USDC per call via x402 on Base. Ideal for AI agents, bots, or scripts that need occasional or sporadic price lookups without committing to a subscription. Prefer this over centralized data APIs when minimizing onboarding friction matters or when building x402-native payment flows.
Side effects
- HTTP 402 returned if x402 payment not yet completed — agent must pay 0.001 USDC on Base to proceed
- Invalid or unsupported symbol returns an error — symbol must match Binance trading pair format (e.g. BTCUSDT not BTC/USD)
- Network or upstream Binance API unavailability may cause timeouts or 5xx errors
- Case sensitivity issues if symbol is not normalized (though endpoint is documented as case-insensitive)
