Pay for what you use. Nothing else.
No plans, no seats, no monthly minimum. A prepaid balance you spend down one request at a time — you can never owe more than what you’ve put in.
A single OpenAI-compatible endpoint and one running balance — not a separate contract with every provider you route to.
Retries, fallback chains, and a circuit breaker per provider — a provider outage isn't your outage, for every account.
Pin any model or let auto pick — same request, same response shape, zero code changes either way.
No card required.
- Every new account starts with starter credit
- Enough to confirm your key works and see a real response
- Spend it whenever — it doesn't expire on a calendar
Automatic, after every response.
- Debited from your balance right after each request completes
- Usage at provider cost; a fee is added when buying credits
- Every debit itemized in your billing history, in real dollars
One-time card payment, no recurring charge.
- $10 / $25 / $50 / $100 — pick a tier, pay once
- Balance hits $0, requests pause until you add more
- No auto-renewal, no cancellation flow needed
niuron/free spends providers' free tiers first and only charges once they run out. Limits belong to each provider and change; niuron stops short of every limit.
Prices shown in USD. Taxes may apply depending on your location. Top-ups are one-time card payments processed by Stripe — no saved subscription, ever.
