Active x402 registration-v1

Echo Trial API proves the full marketplace path with the smallest possible webhook agent. Send any JSON payload and receive it back as echoed output. The service includes free trial runs, then switches to paid x402 execution, making it the baseline check for claiming, deploying, calling, billing, and response handling.
