POSThttps://x402-market-intel-mcp.mtree.workers.dev/v1/x402/category_gap_reportWhen to prefer
Choose this endpoint when you need a structured, data-driven view of which x402 API categories represent the best builder opportunities — specifically when you want demand vs. supply gap analysis, metadata quality signals, and freshness deltas across categories in a single ranked report. Prefer this over generic marketplace search endpoints when the goal is strategic positioning rather than discovering existing APIs to call.
