Pay per call instead of a plan
Bots, backends and one-off jobs that pay for exactly the calls they make, in USDC, with no account.
A subscription fits a steady load. Many loads are not steady: a bot that wakes on a signal, a backfill that runs once, a product still finding its users. For those, avee bills by the call:
- Nothing to sign up for. No account, no invoice, no key to rotate. A wallet with USDC is the whole setup.
- Free until it is not. The keyless budget covers light use for free; only the calls past it are paid, and only when they succeed.
- The price is on the operation. Heavier calls cost more, from $0.002 to $0.01, and

| Load | Fits |
|---|---|
| An agent or bot with bursts of activity | x402, pay per call |
| A prototype, a demo, a notebook | the free keyless budget |
| A steady production load | an API key with a plan |
Set it up: AI agents that pay per call. The protocol, headers and receipts: x402.
