How this service works
ETH futures term structure — carry curve across Deribit, OKX, Bybit — Ed25519 signed attestation
Output
A cryptographically signed (Ed25519) payload containing the ETH/USD futures term structure: the carry curve showing annualized basis/carry at each expiry across Deribit, OKX, and Bybit, enabling analysis of contango/backwardation and cross-exchange arbitrage opportunities.
Example use cases
Example prompt
“Pull the current ETH/USD futures term structure — the carry curve across Deribit, OKX, and Bybit — and give me the signed attestation so I can verify the data integrity.”
Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/term-structure/eth/usdWhen to prefer
Use this endpoint when you need a cross-exchange, cryptographically attested ETH futures term structure for carry trading analysis, basis arbitrage, or on-chain oracle use cases. Prefer this over single-exchange APIs when you need multi-venue consensus on ETH futures pricing, or when you require a signed data payload for trustless downstream consumption.
Side effects
- Payment required (402): x402 micropayment of $0.05 USDC not provided or invalid
- Exchange data unavailable: one or more of Deribit, OKX, Bybit APIs are unreachable
- Stale data: futures prices may briefly lag if upstream feeds are delayed
- Signature verification failure: Ed25519 attestation cannot be validated if response is malformed
- Rate limiting: too many requests without valid payment tokens
