x402 supply census — who is live, in what category, at what price. The full public discovery index (~14.8k resources) normalised into per-category price percentiles and per-origin catalogues, so you can price against the median instead of the loudest listing. Crossed with the half that is not public: which agent client stacks actually crawl a live origin, and therefore which ones will find your endpoint once you ship it.
