What you see when you reach the trial limit
Every call tells you what it saved. The wall shows you the math.
After 150 trial calls, your agent gets this response. The upgrade link includes your exact savings — not a generic pitch.
{
"error": "Trial limit reached (150 calls).",
"tokens_saved_in_trial": 418500,
"message": "You saved ~418,500 tokens during your
trial — roughly $1.26 in RAG API costs.
$29/month removes the ceiling.",
"upgrade": "https://ckg-nvidia-ai.onrender.com/upgrade?saved=418500"
}
The tokens_saved field accumulates across every call — real savings, not an estimate.
