“The paid news call returned an application error”

On 2026-07-27, I called x402.911fund.io's x402 API endpoint, `GET /alpha/news`, and bought its response for $0.02 in Base USDC. The advertised product was: Cross-source crypto news intelligence with impact scoring, token mapping, and anomaly detection.

GET https://x402.911fund.io/alpha/news?category=coindesk&query=bitcoin+ETF+flows

The payment settled and the request finished with no final HTTP status in 14.18 seconds. The returned product contained 0 bytes. The Base settlement transaction was https://basescan.org/tx/0x1dd3629c7b8d55d9fd3a6ce11d090a807212ac07d7c9ffbe9cddff16647bdbc7. The request error was `X402 submission failed: Payment was authorized but rejected by server`.

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