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 an array of historical funding rate records for the requested trading pair, each including the funding rate value and the timestamp or period index. The number of records returned matches the requested limit (default 8, up to 100).
Example use cases
Check funding rate before opening a perp position
“Before I open a long on ETH perps, can you check the current Binance funding rate for ETH/USDT and show me the last 5 periods so I can see if it's trending positive or negative?”
Monitor BTC funding rate trend
“Pull the last 20 funding rate periods for BTCUSDT on Binance — I want to see if the rate has been consistently positive lately, which would mean longs are paying shorts.”
Compare funding costs for altcoin trade
“What's the Binance funding rate for SOLUSDT right now? Give me the last 10 periods so I can estimate how much it'll cost me to hold this position open for a few days.”

Endpoint
POSThttps://chat.sperax.io/api/x402/tools/binance-market/getFundingRate?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need Binance-specific perpetual futures funding rates with historical depth and no API key setup — ideal for DeFi agents making pay-per-use micro-payment calls via x402 on Base. Prefer this over scraping or centralized data providers when you want trustless per-call pricing and don't want to manage API credentials.
Side effects
- Invalid or unrecognized trading pair symbol returns an error or empty result
- Limit value outside 1–100 range may be rejected or clamped
- Binance API downtime or rate limiting may cause upstream errors
- Payment failure via x402 protocol blocks the request
- Requesting a symbol not listed on Binance perpetuals returns no data
