## So wird bezahlt

1. Call the route without a payment header. The 402 response includes accepts, description, and inputSchema.
2. Bedingungen mit einem x402-Client signieren.
3. Repeat the call with the proof in the PAYMENT-SIGNATURE header.

Eine 402-Antwort kostet nichts und löst keine Arbeit aus. Scheitert die Arbeit,
trägt die Antwort charged=false und es wird nicht abgerechnet.
