Market data licensing is tiered, and the decisive line runs between derived values and raw prices. What that costs — and why we're switching off four asset classes for now.

Daily backtests compute the signal from the close and fill at that same close — a price you can no longer trade. We recomputed 7,000+ trades twice (close fill vs. next open) to size the distortion. Result: smaller than the myth.

Everyone talks about the agent economy. From the provider side — I run x402-paid financial endpoints — what agents actually buy today is sober: ingredients. And where the line runs between real and vision.

"Bitcoin is going productive" — they say. Wrapped BTC brings BTC into DeFi. How big is it really, who dominates, where are the catches? A sober map.
