Shares a payout wallet with 31 other endpoints — its adoption is attributed from that shared wallet's traffic, not earned exclusively.

Implied volatility surface for BTC and ETH from Deribit options (public API, no auth). Returns ATM IV (annualized %), IV rank and IV percentile from Kronos iv_history (daily cron), term structure (weekly/1m/3m ATM IV + contango/backwardation/flat shape label), 25-delta risk reversal (BS-approximated strikes), 10-delta wing IVs, max-pain strike across top-5 expiries, and a vol-regime label. Falls back to OKX if Deribit is unreachable. $0.03 USDC via x402.

Composite reliability — the weighted average of the dimensions below, on a 0–100 scale.
Availability
100

How often it was reachable when we probed it (weight 35%).

Latency
100

How quickly it answers when it is up — fast scores high (weight 20%).

Security
100

Whether it serves over working TLS / https (weight 15%).

Transparency
36

Whether the operator disclosed what it does — description, schema, identity (weight 15%).

Activity
1

Observed on-chain payments to this endpoint's wallet — transactions, volume, and distinct paying wallets over the last month (weight 15%; not yet measured when we have not seen its wallet settle).

Confidence 100% — how much probe evidence backs this score. A thin history is flagged, not hidden.

This payout wallet is shared: figures cover all 32 endpoints paid at it, since payments cannot be attributed to one of them. Only payments settled on chains and facilitators we index.

Linked by wallet — likely same operator
