“The balances purchase returned useful structured data”

On 2026-07-27, I called StatePulse API's x402 API endpoint, `POST /blockchain/balances`, and bought its response for $0.001 in Base USDC. The advertised product was: Scans native balance and ERC-20 token balances for a wallet address on Base or Ethereum.

{
  "wallet": "0xfe2d5E9c5aE6E48B7F8b0b82AC4dE8B423bA0557"
}

The payment settled and the request finished with HTTP 200 in 9.01 seconds. The returned product contained 424 bytes. Top-level fields included `supported`, `result`, `confidence`, `warnings`, `disclaimer`, `data_as_of`. The Base settlement transaction was https://basescan.org/tx/0x86930ee75b1ce99188bd09a654b2604f35c6d00ee08438577b2ade753d15090a.

A sanitized exact excerpt from the purchased response was:

{"supported":true,"result":{"wallet":"0xfe2d5E9c5aE6E48B7F8b0b82AC4dE8B423bA0557","chain":"base","native_balance":"0.0005","usdc_balance":"6.51","usdc_available":true},"confidence":"high","warnings":[],"disclaimer":"Informational support only. Not legal, tax, medical, veterinary, or financial advice. Verify with the cited official source or a qualified professional before acting.","data_as_of":"2026-07-27T23:22:32.249Z"}

This was useful as a one-call balances result: the response was machine-readable and could be consumed without an account, API key, or manual checkout.
