Use when your client cannot sign an x402 payment per call (most MCP clients)
Use when your client cannot sign an x402 payment per call (most MCP clients): one payment buys prepaid credit ($5, $20 = $22 credit, $50 = $60) and returns an API key. Send it as X-API-Key on any paid route or MCP tool; each call costs its x402 price and failed calls are refunded. With your key in X-API-Key it tops that key up.

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.
