Free tier returns the top 5; full results are the paid /search endpoint (x402 or MPP) on this host. Calls and paying wallets are P0's own on-chain transfer counts, null where not measured. Not for picking one service for a concrete task (use best_service_for_task), for market-wide totals (use x402_market_stats) or for this host's own products (use list_paid_data_products).

Statistics of the verified x402 seller set (sellers by source and evidence, median declared price; not the whole market) and 30-day x402 market totals from x402stats (CC BY 4.0, attributed in the answer). No parameters. Market-wide totals only, no per-service rows; for individual services use search_x402_services; for this host's own tools use list_paid_data_products.
