Aomi separates revenue from service charges. Your App can earn revenue from priced tools and supported transaction outcomes. Aomi charges for managed model usage and App hosting. ## How the fee model works | Flow | What it covers | Who pays | How it settles | | ------------------- | ------------------------------------------------------ | ----------- | ----------------------------- | | Tool fee | A successful call to a priced App tool | User | USDC through x402 | | Outcome fee | A percentage of value moved by a supported transaction | User | In the signed transaction | | Managed model usage | Model inference funded by Aomi | App builder | Added to your Usage statement | | App hosting | Monthly hosting for an active App | App builder | Added to your Usage statement | Tool fees and outcome fees produce revenue for your App. Managed model usage and hosting are service charges. ## Credits Aomi uses credits to price App tools and measure model usage. **1 Aomi credit = \$0.01 USD.** A tool priced at `100` credits costs the user `$1.00` after a successful call. Failed and blocked calls do not create a tool fee. ## Tool fees You set a flat price for each billable tool in `.pricing.toml`. You also name the wallet that should receive the revenue. When a priced tool succeeds, Aomi records the fee for that user and beneficiary. Aomi can combine small balances before requesting payment. The user then pays the beneficiary directly in USDC through x402. Aomi applies a **10% platform fee** to gross tool revenue. Your net revenue is the remaining 90%. See the complete pricing file schema and examples. ## Outcome fees An outcome fee charges a percentage of value moved by a supported onchain action. You define the percentage in basis points. A rule with `bps = 30` charges 0.30%. Aomi adds the fee to the same smart-account transaction as the requested action. The user reviews and signs both together. The fee uses the asset being moved, so it does not require an x402 payment. Aomi applies a **30% platform fee** to gross outcome-fee revenue. Your net revenue is the remaining 70%. Outcome fees apply only when Aomi can identify a supported transaction flow. Opaque contract calls do not produce an outcome fee. ## Funding model usage Aomi checks who provides the model key for each App request. | Funding source | Who pays the model provider | Charge from Aomi | | ----------------- | --------------------------- | ---------------------- | | App-provided key | App builder | None | | User-provided key | User | None | | Aomi-managed key | Aomi, then the App builder | Provider cost plus 10% | The selected model does not change when the funding source changes. If you use your own provider key, the provider bills that account directly and Aomi does not add a model charge. ## App hosting Aomi charges **\$10 per active App each calendar month**. Hosting appears as a service charge in Usage. ## Read your Usage statement Open **Operate > Usage** in the Developer Platform to review your statement. The Aomi Build Usage statement with revenue, platform fee, service charge, and net summaries | Summary | Meaning | | --------------- | ----------------------------------------------------- | | Gross revenue | Amount collected from users for your Apps | | Platform fees | Aomi's share of App revenue | | Service charges | Managed model usage and App hosting | | Net | Gross revenue minus platform fees and service charges | Use the App filter to review one App. The entries table shows when each charge or earning occurred. ## Worked examples ### User Usage view Assume a user has a monthly allowance of `5,000` credits. During the statement period, they use `3,814.827` credits across `245` model turns. The Usage page reports `$38.15` of model usage after rounding to cents. | Item | Usage | Amount due now | | ----------------- | ---------- | -------------- | | Model usage | `$38.15` | `$0.00` | | Priced tool calls | No charges | `$0.00` | | Outcome fees | No charges | `$0.00` | The monthly allowance covers the complete `$38.15` model charge. The user has about `1,185.173` credits left. No wallet payment is required for compute in this period. Any future outcome fee would settle separately in the asset used by the transaction. ### Builder Usage view Assume a builder operates eight active Apps and uses `$0.65` of Aomi-managed model access during the statement period. The Apps generate no user revenue during that period. | Statement item | Calculation | Amount | | ------------------- | -------------------------------- | --------- | | Gross revenue | No user payments collected | `$0.00` | | Platform fees | No revenue share without revenue | `$0.00` | | App hosting | `8 Apps x $10.00` | `-$80.00` | | Managed model usage | Provider cost plus markup | `-$0.65` | | Net | `$0.00 - $0.00 - $80.65` | `-$80.65` | The negative net means the builder owes `$80.65` for service charges. If an App uses its own model key, its provider usage does not add an Aomi model charge. ## Next Learn how Aomi requests, verifies, and settles USDC payments.
