What is MSVI?
The Mycelia Signal Volatility Index (MSVI) is a five-component weighted volatility index for BTC and ETH. It combines realized volatility, implied volatility, term structure, funding rate stress, and put/call ratio into a single 0–100 index — cryptographically signed with Ed25519 on every paid query.
The widget displays delayed (5-minute cached) unsigned data at no cost. For real-time signed attestations, see the MSVI API docs.
Data
Widget data comes from the free preview endpoint: api.myceliasignal.com/oracle/volatility/btc/usd/preview. Data is cached for up to 5 minutes. For cryptographically signed real-time data, use the paid API at $0.05/query or 500 sats.
Signed API
Need verified, signed data for production use? The paid MSVI endpoint returns an Ed25519 signature you can verify independently. Read the docs →
