How this service works
Perp-vs-spot basis for any USDT pair: the premium or discount in %, a contango or backwardation read, and the funding context that goes with it. Use when you need to answer: Is this perp trading above or below spot?
Output
A JSON object containing the USDT pair symbol, basis percentage (positive = contango/premium, negative = backwardation/discount), a human-readable state label ('contango', 'backwardation', or 'flat'), the current mark price, spot price, and the 8-hour funding rate as a decimal.
Example use cases
Basis arbitrage opportunity scan
“Check the BTCUSDT perp vs spot basis for me — is the perp at a significant premium or discount, and is there a funding rate that makes a basis trade worthwhile?”
Market sentiment read via funding context
“What's the funding rate and basis state for ETHUSDT right now — is the perp market leaning bullish or bearish relative to spot?”
Pre-trade contango check
“Before I open a long on AVAXUSDT, can you tell me if the perp is trading above or below spot and what the 8-hour funding rate looks like?”
Technical details
Endpoint
GEThttps://x402.ochinimus.app/api/basis?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a single-symbol, real-time snapshot of the perp-vs-spot relationship including basis percentage, market state classification, and funding rate context — especially for basis trading analysis, pre-trade sentiment checks, or funding arbitrage assessment. Prefer this over general price feeds when the perp premium/discount and funding context are the specific signals needed.
Side effects
- Invalid or unsupported symbol returns an error or empty data
- Symbol must be a valid Bybit USDT perp symbol (e.g. SOLUSDT, not SOL/USD)
- Stale or delayed data if upstream exchange feed is lagging
- Payment failure via x402 protocol blocks the response
- Missing required 'symbol' query parameter causes a 400-level error
