How this service works
BTC/USD spot-futures basis and annualized carry across 5 exchanges — Ed25519 signed attestation
Output
Returns the BTC/USD spot-futures basis (the price difference between spot and futures), the annualized carry rate expressed as a percentage, and data aggregated from 5 exchanges — all wrapped in an Ed25519-signed attestation for cryptographic verifiability.
Example use cases
Example prompt
“What's the current BTC/USD spot-futures basis and annualized carry right now, aggregated across multiple exchanges, with a signed attestation I can verify?”
Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/basis/btc/usdWhen to prefer
Use this endpoint when you need a cryptographically attested, multi-exchange aggregated BTC/USD basis and carry figure — especially in DeFi, on-chain protocols, or any context where trust-minimized proof of the data is required. Prefer this over single-exchange REST feeds when you need signed provenance or cross-exchange consensus on the carry rate.
Side effects
- Exchange data unavailable — one or more underlying exchanges unreachable, partial or no data returned
- Payment not processed — x402 payment required, 402 response if payment header missing or invalid
- Signature verification failure — Ed25519 attestation cannot be verified if key is stale
- Rate limiting — too many requests in a short window
- Stale data — if market feeds lag, basis figures may be slightly delayed
