How this service works
AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.
Output
Returns a time-series of open interest values for the specified trading pair aggregated at the requested period (e.g. 5m, 1h, 1d), including timestamps and open interest figures sourced from Binance futures data.
Example use cases
Pre-trade futures sentiment check
“Before I open a long on ETH, can you pull the 4h open interest data for ETHUSDT on Binance so I can see if positions are building up or unwinding?”
Daily crypto market briefing
“Give me the open interest trend for BTC over 1-day periods on Binance — I want to include it in my morning market summary.”
Detecting open interest spike on altcoin
“I think something is happening with SOL — can you fetch the 15-minute open interest data for SOLUSDT so I can see if there's been a sudden spike in futures positions?”
Technical details
Endpoint
POSThttps://chat.sperax.io/api/x402/tools/binance-market/getOpenInterest?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need Binance-specific futures open interest data without managing API keys — especially suitable for AI agents that can pay per-request via USDC on Base. Prefer this over direct Binance API integration when you want frictionless, pay-as-you-go access to open interest time series for trading analysis, market monitoring, or DeFi intelligence workflows.
Side effects
- Unknown or malformed symbol returns an error — e.g. using a delisted pair or typo like 'BTCBUSD' when unavailable
- Invalid period string (not one of 5m, 15m, 30m, 1h, 2h, 4h, 6h, 12h, 1d) causes a validation error
- Payment failure via x402 if USDC balance is insufficient or wallet not connected
- Binance data unavailable during exchange downtime or rate limiting
- No futures market exists for the requested pair (e.g. very small altcoins)
