When credits run out

You get a 402 error:

{ "error": "insufficient_credits", "message": "Insufficient credits." }

No request goes through. Add more credits and try again.

Check your balance

From code:

r = requests.get("https://ninjachat.ai/api/api-keys",
    headers={"Authorization": f"Bearer {os.environ['NINJACHAT_API_KEY']}"})
print(r.json()["billing"]["balanceFormatted"])  # → "$42.50"

Or from your Developers dashboard.

Low-balance warnings

When your balance drops below $5.00, every API response includes a balance_warning field:

{
  "message": { "role": "assistant", "content": "..." },
  "cost": { "this_request": "$0.006" },
  "balance": "$3.50",
  "balance_warning": {
    "warning": "low_balance",
    "threshold": "Balance is $3.50. Consider adding credits soon."
  }
}

At $1.00 or less, the warning becomes "critical_low_balance". Use this to trigger alerts in your app before hitting insufficient_credits.

Purchase history

View all past credit purchases:

r = requests.get("https://ninjachat.ai/api/api-keys/transactions",
    headers={"Authorization": f"Bearer {os.environ['NINJACHAT_API_KEY']}"})

for t in r.json()["transactions"]:
    print(f"{t['timestamp']} — {t['amount']} ({t['type']})")

Supports limit and offset query params for pagination.
