### `screen_payment` (~230 tokens)

Screen a payment before paying

Screen a counterparty an agent is about to pay. Runs entirely offline: address sanity, dynamic-payTo comparison, transport check, and your spending policy. Returns allow / review / block with reasons. Advisory: the caller decides. Set FRISK_API_KEY to add hosted reputation signals.

Input parameters:

- `allowedAssets` (array): Assets the agent is permitted to pay in.
- `amount` (number): Amount the agent is about to pay.
- `asset` (string): Asset symbol, e.g. USDC.
- `counterparty` (string, required): The address the agent intends to pay, e.g. an 0x EVM address.
- `endpoint` (string): URL that quoted the payment. Used to check transport safety.
- `maxPerCall` (number): Spending ceiling for a single call.
- `observedPayTo` (string): The payTo address the endpoint actually returned for this request. If it differs from the counterparty, that is the dynamic-payTo swap.
- `strictness` (number): 0 is permissive, 1 is paranoid. Defaults to 0.3.
