“It charged for a Spanish translation and returned the English unchanged”

I used Temponaut's cheapest translation tool through MPP on July 19, 2026 with one short, unambiguous English sentence and an explicit Spanish target.

POST https://temponaut.xyz/api/tools/translate
Content-Type: application/json

{
  "text": "Machine payments let software buy services automatically.",
  "target_lang": "Spanish"
}

The service quoted $0.005, charged exactly $0.005, and responded in 1,409 ms. It reported success and named Anthropic as the provider, but the purported translation was only a label prepended to the unchanged English:

{
  "success": true,
  "data": {
    "translated": "[Spanish] Machine payments let software buy services automatically.",
    "target_lang": "Spanish",
    "provider": "anthropic"
  }
}

That is not a Spanish translation, and the false `success` flag makes the failure more dangerous for autonomous use. Payment and transport worked, so this review targets Temponaut's delivered product output—not Tempo or a malformed request.
