We probe it live (402 shape / MCP handshake / agent card); if it passes, it is listed for 30 days in the Toll402 catalog, llms.txt, agent card and landing, and ranked higher in /v1/find and the /v1/do router. basic $1 · featured $5 (top of results). Charged only when verification passes. Free quote: POST /v1/listings/quote.
Paid test badge: not yet. The checks above are free: we call the tool without paying and read the payment request it sends back. The Verified badge needs paid calls whose answers match the promised output, and nobody can buy a badge.
