How this service works
MSXI Bitcoin market sentiment index — funding rate, long/short ratio, open interest momentum and liquidation signals combined — Ed25519 signed attestation
Output
Returns a JSON object containing: sentiment index value (0-1 float), regime label (e.g. NEUTRAL/BULLISH/BEARISH), Ed25519 signature over a canonical string, signing public key, confidence score, degraded flag, individual component weights and values (funding rate, skew, put/call ratio, term structure, basis), computation timestamp, and method version. The canonical string and signature allow downstream consumers to cryptographically verify the attestation.
Example use cases
Smart contract collateral decisions
“I need a cryptographically signed Bitcoin sentiment reading right now. Fetch the MSXI index with the full Ed25519 attestation so I can verify it on-chain and use it to automatically adjust my lending pool's BTC collateral requirements based on whether we're in a bullish or bearish regime.”
Trading bot regime confirmation
“Before my bot opens a new BTC position, check if Bitcoin sentiment is actually bullish using the Mycelia MSXI composite. I want the regime label, the confidence score, and breakdowns of funding rate and put/call ratio so I know if this is a strong signal or just neutral noise.”
Risk dashboard for fund managers
“Pull the current MSXI Bitcoin sentiment index with all component values — funding rate, basis, term structure, skew, and PCR. I need this signed and timestamped for our compliance report so we can show LPs exactly what on-chain sentiment data was driving our BTC exposure decisions today.”
Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/sentiment/btc/usdWhen to prefer
Choose this endpoint when you need a cryptographically signed, multi-factor BTC/USD sentiment composite (not just price) that is verifiable on-chain or in smart contracts. Prefer this over raw price feeds when the use case requires regime classification (bullish/bearish/neutral), derivatives-derived sentiment signals (funding rate, skew, PCR, term structure, basis), or tamper-proof attestations for trustless downstream consumption. Not suitable if you only need spot price — use the price oracle endpoints for that.
Side effects
- Payment failure (402): x402 micropayment not accepted or insufficient USDC — no data returned
- Degraded signal (degraded:true in response): one or more underlying data sources unavailable, index computed with reduced confidence
- Service unavailable (503/timeout): oracle backend unreachable
- Invalid signature verification: consumer-side key mismatch or payload tampering detected after receipt
