ONE PAID CRYPTO LAYER for one coin, with the shape named so you do not have to probe for it. layer=surface - the implied-volatility surface: {expiries:[{days, iv:[...]}], moneyness:[...]}. moneyness is a FRACTION of spot running about -0.20 to +0.20 and indexes into each expiry's iv array; iv values are percentage points; days can be fractional for same-week expiries. ⚠ A NULL CELL IS A GAP IN THE BOOK, NOT A ZERO - it means no contract is priced at that strike for that expiry, and averaging over it fabricates a quote. layer=etf_flows - the US-listed spot funds' book: {ticker, cumulative_usd, days:[{date, net_usd}]}, daily net creations and redemptions. This is the ISSUERS' book, a different book from the offshore options chain, and the two are never summed. layer=history - this coin's funding and open interest ranked against ITS OWN sample history, with the sample size n carried alongside every percentile. A percentile without its n is the number people quote when they mean 'high'. A coin that does not carry a layer answers 200 with available:false and a reason, never an empty object: empty would read as 'there were no flows today', which is a claim about the market rather than about our coverage.
