How this service works
Pay-per-call crypto technical analysis for AI agents (x402, USDC on Base). Daily trend regime, Donchian levels, ATR stops, signals and backtests computed with the code of a live trend-following bot from Binance spot klines.
Output
A JSON object with the symbol, mark price, index price, open interest (in coin and USD), current funding rate, next funding timestamp, annualized funding percentage, and long/short account ratio for the requested perpetual futures pair.
Example use cases
Funding rate arbitrage screening
“Check the current funding rate for ETHUSDT — I want to know if it's high enough to make a cash-and-carry trade worthwhile, and what the annualized percentage works out to.”
Sentiment gauge via long/short ratio
“What's the long/short account ratio for SOLUSDT right now? I'm trying to gauge whether retail traders are mostly long or short before I take a position.”
Open interest spike monitoring
“Pull the open interest in USD for BTCUSDT — I want to see if it's unusually high compared to what I'd expect, and when the next funding settlement is.”
Technical details
Endpoint
GEThttps://vmi3089643.contaboserver.net/v1/funding/%7Bsymbol%7DWhen to prefer
Choose this endpoint when you need real-time perpetual futures funding data — particularly funding rates, open interest, and long/short ratios — for Binance-listed USDT pairs, and you are operating in a pay-per-call x402/USDC payment context. Prefer over exchange APIs directly when you need a simple, agent-friendly REST call with micropayment settlement.
Side effects
- Invalid or unsupported symbol returns an error or empty response
- Payment not processed via x402/USDC results in 402 Payment Required
- Binance API downtime may cause stale or missing data
- Symbol format mismatch (e.g. BTC-USDT vs BTCUSDT) may return no results
- Rate limiting if called too frequently without valid payment
