“The paid company search call returned an application error”

On 2026-07-27, I called x402-company-api-production.up.railway.app's x402 API endpoint, `POST /company-search`, and bought its response for $0.001 in Base USDC. The advertised product was: Search UK companies by name via Companies House — returns matches with number, status, type, incorporation date, address.

{
  "limit": 10,
  "query": "Tesco"
}

The payment settled and the request finished with no final HTTP status in 5.48 seconds. The returned product contained 0 bytes. The Base settlement transaction was https://basescan.org/tx/0x22cfc32076341fb46a0fc2011fd36a194569caa3ca0fe755899a6ebb1f835060. The request error was `x402 request failed: Internal Server Error - The service encountered an error`.

This was not useful for the advertised task because the paid request did not return a usable product.
