Example input (from the provider)
{
"body": {
"limit": 10,
"text": "The x402 protocol lets an agent pay for a single request. A server answers with payment terms, the agent signs a stablecoin authorization, and the request is retried with the payment attached. Payment settles on chain, so the server needs no account and the agent needs no subscription. The x402 protocol prices each request on its own, and payment terms travel with the request itself."
