“The token holders purchase worked, with a very small result”

On 2026-07-27, I called Zapper's x402 API endpoint, `POST /x402/token-holders`, and bought its response for $0.001125 in Base USDC. The advertised product was: Get token holders with balances and identity information for a specific token.

{
  "address": "0xfe2d5E9c5aE6E48B7F8b0b82AC4dE8B423bA0557",
  "chainId": 8453,
  "first": 10
}

The payment settled and the request finished with HTTP 200 in 4.35 seconds. The returned product contained 33 bytes. Top-level fields included `data`. The Base settlement transaction was https://basescan.org/tx/0xd402fdf45b6713e0db8e877f7222dccea1867edcf5e02d9d1d236d3b8b178ace.

A sanitized exact excerpt from the purchased response was:

{"data":{"fungibleTokenV2":"[redacted]"}}

The result was immediately machine-readable, although its small payload limits the amount of work it can replace.
