Agent Store docs

Everything an agent needs: the x402 flow, per-SKU schemas, and how to verify our signatures.

x402 payment walkthrough

  1. Call any paid endpoint with no payment header.
  2. You receive 402 Payment Required with accepts[]: scheme exact, network base, asset USDC, payTo, and the atomic amount.
  3. Sign an EIP-3009 transfer authorization for that amount and retry with X-PAYMENT: base64(paymentPayload).
  4. We verify and settle through the x402 facilitator, then return the result plus an X-PAYMENT-RESPONSE header with the settlement (including the tx hash).
  5. Nonces are single-use — replays return 409.

Response envelope

{
  "paid": true,
  "price_paid_usdc": 0.1,
  "public_key": "<base64url Ed25519>",
  "result": { "...": "sku-specific payload" },
  "result_id": "<uuid, reusable for add-ons>",
  "schema_url": "https://robauto-agent.lovable.app/api/public/schema/scan.json",
  "settlement": { "success": true, "transaction": "0x..." },
  "signature": "<base64url>",
  "signed_at": "2026-01-01T00:00:00.000Z",
  "sku": "scan"
}

Keys are ordered deterministically at every level. The signature covers the canonical (recursively key-sorted) JSON of result only, so you can re-serialize and verify it independently.

Verify a signature — TypeScript

const body = await res.json();
const canonical = (v: any): any =>
  Array.isArray(v) ? v.map(canonical)
  : v && typeof v === "object"
    ? Object.fromEntries(Object.keys(v).sort().map(k => [k, canonical(v[k])]))
    : v;

const msg = new TextEncoder().encode(JSON.stringify(canonical(body.result)));
const b64u = (s: string) => Uint8Array.from(atob(s.replace(/-/g, "+").replace(/_/g, "/")), c => c.charCodeAt(0));
const key = await crypto.subtle.importKey("raw", b64u(body.public_key), { name: "Ed25519" }, false, ["verify"]);
const ok = await crypto.subtle.verify({ name: "Ed25519" }, key, b64u(body.signature), msg);

Python

import base64, json
from nacl.signing import VerifyKey

def canon(v):
    if isinstance(v, list): return [canon(x) for x in v]
    if isinstance(v, dict): return {k: canon(v[k]) for k in sorted(v)}
    return v

def b64u(s): return base64.urlsafe_b64decode(s + "=" * (-len(s) % 4))

msg = json.dumps(canon(body["result"]), separators=(",", ":")).encode()
VerifyKey(b64u(body["public_key"])).verify(msg, b64u(body["signature"]))  # raises if invalid
