How this service works
Normalized crypto perpetuals snapshot across Binance, Bybit and Hyperliquid in one call: current funding rate, funding interval, annualized funding (APR %), mark price, index price, premium/basis %, open interest (base units and USD). Query: ?symbols=BTC,ETH,SOL (max 10). JSON only, ~20s cache, partial results if a venue is down.
Output
Returns per-asset derivatives market data including mark price, index price, venue (e.g. Binance), funding rate, funding APR (annualized percentage), open interest in native units and USD, premium percentage, and funding interval in hours. Also includes lists of successfully queried venues and any failed symbols.
Example use cases
Crypto funding rate arbitrage tracking
“Check the funding rates and open interest for Bitcoin, Ethereum, and Solana right now – I need to compare which has the best yield opportunity across derivatives markets.”
Multi-asset derivatives snapshot monitoring
“Give me a real-time snapshot of the mark price, index price, and funding APR for BTC, ETH, XRP, and AVAX – I want to see which ones have the highest funding spreads today.”
Perpetual swap premium analysis
“What's the current mark price premium and funding interval for Bitcoin and Ethereum futures? I need to understand if we're in contango or backwardation right now.”
Technical details
Endpoint
GEThttps://data.greeneris.io/v1/derivs/snapshotWhen to prefer
Use this endpoint when you need real-time crypto derivatives data (funding rates, open interest, mark/index prices) for up to 10 assets in a single pay-per-call request without requiring account registration or API key setup. Prefer over exchange APIs directly when you want a unified, commoditized, pay-as-you-go interface with no subscription overhead.
Side effects
- Invalid or unsupported symbol returns it in the 'failed' array
- Requesting more than 10 symbols may be rejected or truncated
- HTTP 402 returned if payment not provided — must pay 0.005 USDC via x402 protocol on Base before retrying
- Venue API downtime may cause symbol to appear in 'failed' list
- Malformed symbols parameter (e.g. extra spaces) may cause parse errors
