Generate or grade an agent card (the /.well-known/agent-card.json an agent publishes for A2A and AgentWorld-style registries). Generate builds a structurally valid card from your fields; grade scores a supplied card and itemizes its defects. Use this when you are registering an agent and want the card right the first time.

This API is run by its own provider and paid directly through x402. We list it so you can find it; we don't route or hold the payment.

import { x402Client, wrapFetchWithPayment } from "@x402/fetch";
import { registerExactEvmScheme } from "@x402/evm/exact/client";

const client = new x402Client();
registerExactEvmScheme(client, { signer: agentAccount });

const pay = wrapFetchWithPayment(fetch, client);
const res = await pay("https://stall-row-production.up.railway.app/v1/card-smith", { method: "POST" });
console.log(await res.json());
