01
Top up the wallet
Pay in RWF with MTN Mobile Money, Airtel Money or a card. The credits land on your account balance immediately.
Pricing
Buy credits. Pay per call. Keep the rest.
CircuitNotion is not a subscription. You fund a wallet in Rwandan Francs, spend it request by request across every model we route to, and what you do not use stays yours.
02
Call the API
Every request draws down the balance at the rate published for the model, plus a flat 15% platform and routing fee.
03
Keep the remainder
Whatever you have not spent stays in the wallet. At zero the API returns HTTP 402 instead of charging an overage.
What a request costs
The model rate, plus 15%
Per-model rates move when providers move theirs, so they are published where they can stay current rather than copied onto a marketing page.
Your key can also read the catalog directly, so an application can check what it is about to be charged for before it calls:
GET https://api.circuitnotion.com/v1/modelsUsage and remaining balance are visible on the Developer Platform as you spend, and consulting engagements are quoted separately from API credits.

FAQ
Questions about billing
What people ask before they put money on a balance.
How much does the CircuitNotion API cost?
Each request is charged at the rate published for the model you called, plus a flat 15% platform and routing fee. Rates differ per model and change as providers change theirs, so the current numbers live in Pricing & credits on the Developer Platform and in the live model catalog rather than on this page.
Is there a subscription or a monthly minimum?
No. There is no plan to choose, no seat to pay for and no minimum spend. You buy credits when you want them and the API draws on that balance as you use it.
Do credits expire?
No. Credits stay in your wallet until you spend them, so a quiet month costs you nothing and an unused balance is not written off at the end of a billing cycle.
Can I pay without an international card?
Yes. Top-ups go through MTN Mobile Money, Airtel Money or a card, in Rwandan Francs, processed by DPO Pay. You do not need a foreign card or a foreign billing address.
What happens when my balance runs out?
The API returns HTTP 402 and declines the request. Nothing is charged as an overage and no invoice arrives later — you top up when you decide to.
Does one balance cover every model?
Yes. The same wallet and the same API key reach CircuitNotion’s own models and the OpenAI, Anthropic, DeepSeek and Moonshot models we route to, so you are not funding an account per provider.
How are consulting projects priced?
Separately. Training, data work and custom builds are quoted per engagement — API credits cover API usage only.
