ActiveTool of The Stall
declared in 4.82.0
Discovers active x402 APIs with verified organic USDC settlements — shows which endpoints have genuine payer breadth across the ecosystem. Sourced from on-chain settlements, not catalog listings. Filter by category, price range, and minimum unique payers. Useful before wiring a workflow to an external x402 endpoint: confirms it is active with multiple independent payers, not private infrastructure or a dead listing.
