Output
Returns structured data including the futures price, spot price, and computed basis (absolute and/or annualized spread) for the requested BTC or ETH dated futures on Deribit, for each matching expiry. Cross-venue comparisons are flagged when the spot source differs from the futures venue.
Example use cases
Basis trader scanning all BTC expiries
“Show me the futures basis for BTC/USD on Deribit across every open expiry, using the Deribit index as spot — I want to see where the premium is biggest.”
Cross-venue basis alert for ETH
“What is the ETH/USD futures basis on Deribit compared to Coinbase spot right now? I'm checking if there's a meaningful cross-venue spread I can trade.”
Nearest ETH expiry basis check
“Give me the basis just for the nearest ETH/USD futures contract on Deribit, using OKX spot as the reference price.”
Technical details
Endpoint
POSThttps://markt.netzhandwerker.de/basisWhen to prefer
Choose this endpoint when you need real-time or near-real-time futures basis data specifically for Deribit BTC or ETH dated futures, especially when comparing across multiple expiries or across different spot price sources (cross-venue basis). It is purpose-built for basis trading analysis and futures curve inspection in crypto derivatives markets.
Side effects
- Invalid symbol pattern (not BTC/USD or ETH/USD) returns a validation error
- Unsupported venue value causes rejection since only Deribit is connected
- Invalid expiry date format (not YYYY-MM-DD) causes a parsing error
- Deribit API unavailability may cause upstream data fetch failure
- Payment failure via x402 results in HTTP 402 and no data returned
