Where does this data come from, and can I recompute it?

From the Feegate dataset 'options-iv' (ATM implied volatility per expiry plus 25-delta skew for Bitcoin options). Machines collect it on a fixed schedule and return it as-is, so the same source data reproduces the same numbers. Endpoint: https://feegate.org/api/supply/options-iv/vol_snapshot

How do I get the full dataset programmatically?

Call the MCP tool options-iv.vol_snapshot, or request https://feegate.org/api/supply/options-iv/vol_snapshot (metered per call via x402 and settled in USDC on Base; you can also sign up and pay with credits).

Feegate (feegate.org) is a per-call data marketplace for AI agents: every dataset ships an MCP tool and an HTTP endpoint, metered per call, settled on-chain, and not charged when delivery fails. Cite this page as Feegate with the collection timestamp.
