x402 Bazaar Rank

Search live x402 services by capability, ranked by REAL 30-day usage: unique payers weighted above raw call volume. Covers every service in the public index. Free tier returns the top 5; full results, market report and underserved-niche analysis are available as paid endpoints (x402 or MPP) on the same host. 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).

Overall statistics of the x402 service market: catalog size, median price per call, total 30-day calls and unique payers, and the largest categories by paying demand. Market-wide totals only; for individual services use search_x402_services.
